INTRODUCTION.

The object of this paper is to give the literature on
the Palfeozoic Crustacea and to aid students and paleeon-
tologists in their researches. It is the result of more or
less constant work during the past decade. It gives a
list of authors, and includes an index of the species de-
scribed in each work.

I am well aware that the value of a work of this kind
depends upon the care and labor given to its compila-
tion. Every possible means of obtaining accurate in-
formation from a miscellaneous class of literature in
many languages has been used, and it is hoped that
there ar^ but few errors and omissions.

I would thank those into whose hands this paper may
fall for any information that would add to its value as a
working hand-book.

Calymene blumenbachii.

An important result of the investigations of this author was gained by
the entinciation and establishment of the following principles:

1st. That trilobites differ only from the other articulata in points of
minor imisortance, and that, beyond a doubt, they belong to this group.

2d. That Trilobites exhibit the greatest analogies with the Isopodes.
Later investigations, with the discovery of ambulatory appendages, have
not changed this classification. Dr. Henry Woodward remarks in the
Ency. Britannica, article Crustacea, p. 659, that "there seems, however,

8 CALIFORNIA ACADEMY OF SCIENCES.

no good reason to urge against the couclnsion that the Trilobita were an
earlier and more generalized type of crnstacea, from which the later and
more specialized Isopoda have arisen."

3d. That the want of feet seems to be a necessary characteristic of their
skeleton formation, although this point still remains problematical.

from Coal Brook Dale, which had been included with it in the genus Limu-
Ins, and it was proiJosed to removed all these Coal-Measure Crustacea from
that genus and group them into a new one iinder the name of Stej-opis.

Entomolithus paradoxus andEntom. incoguitiis, i^l. 3, fig. 6, have been,
referred by Sternberg to Tril. tessini. Enlom. expansus caput truncatus,
to Tril. hausmanni Eutom. paradoxi caput la^ve, to Tril. sulzeri.

The last reference is doubtful. Born cites Wilken's figure Tab. 7, fig.
36, vs^hich is a direct copy of Lhywd's illustration of Trinucletis . The
Entomolithus from Andrarum is probably Olenus truncatvs. Bromell's
woodcut on i>. 77 is given as a reference for this species. The Entom.
expansus capite IcBvi tuberculis niiUis (Acta Soc. Reg. Holm, 1759, Tab.

This work was continued in several parts through this volume, but it is
only at p. 493, in the section called " De lapidibus insectiferis Scanices et
Gothicis," that the Trilobites are treated. AVe have there the Oleni of the
alum slate and Agnostus pisiformis.

A separate edition of the work was printed at Stockholm and Leipzig,
in 1740, bearing the same title as the original work.

This work contains rough woodcuts of Olenus truncatus Brtinu, Agnos-

The author illustrates plate 2, figs. 1-4, several sections of Phacops
bufo Green, from Capon, Virginia.

The first figure shows a transverse section made in the rear of the ej'es.
Immediately below the axis there is a large cylindrical spot and another
on the right side occupying the position of a posterior pair of cephalic
legs. Fig. 4 gives a longitudinal section, with two spots corresponding to
two thorax segments.

On p. ix we find the following remarks: " Upon a transverse section of
the thorax of a specimen of Calymene from North America. We perceive
a ferruginous spot which occupies the place where one ought to find the
cylindrical trunk of the animal, and a little lower down on the right side
we distinguish another spot of the same kind, but of different form, which
resembles approximately the marks which might have been made by the
print of a foliaceous foot similar to that of a BranchiopodiB. In another
specimen we find upon a longitudinal fracture two spots of the same color,
but straight and elongated, which seem to correspond to two distinct
rings of the thorax, and which could very well be of the same nature as
those seen uiaon the face of the preceding specimen."

The author remarks iu regard to Cahjmene spinifera: "Among the
specimens of Lower Silurian fossils of Missouri in the collection of my
friend J. N. Nicollet, Esq., I noticed the tail of this curious trilobite, -which
has on the back of one of the articulations of the middle lobe an erect
curved spine, curved towards the caudal extremity, and more than one-^
third of an inch in length."

In the first part of this work, iu the list of fossils given on p. 22, Eduard
von Eichwald refers three species to Cryptonymus; a generic name which
he used in 1825 for an entirely diflferent series of fossil Crustacea. In the
present work he siibstitutes the name for such species as C'alymene vario-
Inris, C. piinctatus, G. worthii, etc. The name is used without a generic
description, and only indicated by the above named species.

The author makes the following remark: "If, in the end, all the five
ringed species should prove to have long heads, and those with 6 thoracic
segments to have short and rounded ones, the latter section may be con-
veniently distinguished from the former as a subgenus, under the name of
Brachampyx .

The author erroneously included the type of the genus, Ampyx nasiitits
Dalm., in his new subgenus; the term is misplaced and should be aban-
doned.

This paper contains the earliest account of Trilobites. The author dis-
covered two fragments and one entire specimen of Ofjygia huchii near
Llandeilo, in Carmarthenshire. Lhwyd says in his letter that he did not
know what to make of these fossils. The Ogygia ffig. 10) he refers to the
skeleton of an unknown fish. Fig. 8 represents the head of a species of
the genus Trinucleus.

sam, plate 22, fig. 2. He also gives a description and figure of Trinucleus
flmbriatum vulgare, plates 22 and 23, on which R. I. Murchison afterwards
founded the genus Trinucleus.

Liudaker's description can easily be recognized as that of a Trinucleus,
approaching T. ornatus Sternb. He indicates the limb with the genial
angles extending into spines, also the three protuberances of the head,
and the trilobation of the body, with its divisions into segments, The
anthor also states that the fossil is often found extended or rolled into a
ball.

The au.thor makes the following remarks ou Callaway's paper, Quart.
Jour. Geol. Soc, vol. 33. p. 652: " 1 do not think that Gonocoryphe monile
is nearly related to such species as C. striata. By the strongly lobed
glabella and the dotted marginal furrow it approaches to Euloma."

Conophrys can hardly be separated from the Shumardia of Billings.

As, to Lichapyge, it cannot have any affinity to Paradoxides and hardlj'
to Lichas, it is most nearly allied to Bemopleurides; the subgenus Platij-
peltis to Niohe.

The author remarks that "it is evident from the new specimen of Ellip-

in Emmon's American Gaol., pi. 1, fig. 18, that this trilobite is a Paradox-
ides related to the group of P. spinosiis; perhaps identical with the P.
harlani of Braiutree. Besides, the trilobite figured pi. 1, fig. 16, and
called Atops trilineatus, is a true Sao, which genus is the most character-
istic of the primordial fauna of Bohemia and Scandinavia."

Somatrikelon megalomaion, p. 74, u. g. aud u. sp.

This new genus under the law of priority should replace the genus
Phacops if it were not for the objection to Somatrikelon, which means
the same as the word Trilobite used for the class. The name given to
the species " having ver}- large eyes " corresponds to that given by Dr.
Emmrich to the genus Phacops.

The author refers "this very curious animal to the vermes class," aud
remarks: "At first view it appears to have three distinct bodies and one
head, which is owing to the former being very broad (nearly one-half an
inch) and divided throughout its length by two deep clefts, one ou each
side of the central part or back, which is elevated a fourth of an inch above
the sides, is convex, and terminated at one end by a large head, furnished
with unusually prominent eyes and a mouth formed like that of a snapping
turtle. From the Falls of the Ohio." The following diagnosis is given:
"Corpus tripartitum, rugosum, sinuatum; extremitate altera acuminata
curvataque dorso, arcuato, serie tuberculorum utro, bique, capite subro-
tundo, oculis peramplis."

The aiathors follow Salter's division of Remopleurldes in two sections:

1. Remoiileurides . The glabella devoid of furrows.

2. Section Caphgra. Glabella with three pairs of furrows, not inflated.
The genus Illcenus is subdivided into the sections Dysplanus and lUcenus.

Under the genus Ampyx the authors use Raphiophorus, Lonchodomus and
Ampyx in the sectional sense. On p. 288 Ampyx macconochiei n. sp. is
referred to the genus Trinucleus.

Report of a geological survey of Wisconsin,

Iowa and Minnesota, and incidentally a portion of Ne-
braska Territory. Philadelphia, 1852, 638 pp., 27 pis.,
16 sections and maps.

Dr. Owen described four new genera of trilobites under the names of
Dikelocephalus, Lonchocephalus, Crepicephalus and Menocephcdun. The
second genus is now classed as a synonym to Anomocare, with Anomocare
chippeivaensis and A. hamulus described in the report. There is a third
si^ecies mentioned by Owen on p. 624, and also pi. la, fig. 15. Pygidium
of Lonchocephalus ?, with long, slender, divergent caudal spines; also a
similar pygidium, figured jil. la, fig. 13, as Dikelocephalus ? loive^isis.
Walcott, Bull. U. S. Geol. Sur., No. 10, p. 36, places the latter species
under a subgeniis to Ptychoparia, using Dr. Owen's Crepicephalus for it,
on account of the peculiar pygidium, overlooking, however, the fact that
Owen has referred a similar pygidii;m directly to his genus Lonchoceph-
alus on p. 624 of his report. Under the law of priority the genus Ptycho-
paria replaces Crepicephalus, and the latter name should be cancelled
in toto, and not be retained in a modified sense. Lonchocephalus forms an
exception to this rule, if we divide the genus into two sections, retaining
Anomocare for the two species described by Owen, and Lonchocephalus, in
•a restricted sense, for "the pygidiiim with long, slender, divergent caudal
spines," including the Dikelocephalus ? ioioensis Owen.

The author also describes and illustrates the following species: 1, Dikel-
ocejihalus minnesolensis n. sp. 2, D. miniscctnsis n. sp. 3, D. pepinensis
n. sp. 4, D. ? iowensis n. sp. 5, D. granulosus n. sp. 6, Lonchocephalus

The genns Stylonurus was proposed by Mr. David Page in his paper
read -before the Association, and the name published in his "Advance
text-book of geology," 1856, where he also figured and named the then
only known species Stylonurus poivriei, but without giving any description.

Two new species are provisionally named Stylonurus spinipes and S.
clavipes in allusion to their pointed style-shaped caudal termination, and
the characteristic form of their swimming paddles or third pair of organs,
which spring from the under side of their cephalo-thorax.

The author also mentions the genera Beyrichia, Ceratiocaris, Himan-
Ihopterus, Pterygotus and Kampecaris.

Dithyrocaris (Scouler). In the Kecords of Science, 1835, Dr. Scouler
first noticed this crustacean, and, depending as a principal character on
the lateral appendages, he pointed oiat its analogy to the genera Cyclops
and Apus. He also noted two new species in a paper read before the
British Association at Glasgow. Dr. Scouler having subsequently altered
his views of the affinities of the genus, he replaced the original name of
Argas by that of Dithyrocaris. The authority for this change is generally
quoted from Portlock.

After a careful study of the Limuli belonging to Prestwich's collection,
and also other specimens, this author remarks, that they are divisible into
two well-marked genera:

(a) Those having movable thoracic segments and anchylosed abdomina
ones; to be included in the genus Belinurus, namely Beliniirus trilobltoidesl

(b) Those in which the thoracic and abdominal segments are not divided,

The author remarks " that he found the specimens during an excursion
along the shores of the Baltic Sea, in a red limestone." He has the merit
of referring these fossils to the class Crustacea.

This paper was read Dec, 1846, aiid published in the Bull. Soc. Geol.
France, vol. 4, 1847, pp. 309-328.

The author gives a general discussion of organization and structure of
the Trilobite especially of the eye.

The text gives a list of 20 species with figures of the following: Trinu-
cleus pongerardi n. sp. Prinocheilus n. sp., P. verneuili n. sp. (Calymene)
Nileus heaumonti n. sp. Calymene tournemini n. sp. Phacops dnjardini

In Institute de France Acad. Sci., vol. 27, 1848.

The author remarks on the fossil Crustacea described by Guettard from
Angers in the year 1757: that Burmeister correctly indicated the genus of
the species described by Brongniart as Ogygia desmaresti, but it is to
be regretted that he gave it the new name of Illcenus giganteus inasmuch as
Brongniart had already named it.

The author remarks: " The puncta are almost always arranged in radiat-
ing rows; three, four, or more holes in each row, and these being at equal
distances they form concentric lines. In T. granulatus, two of the rows
are se^jarated by a furrow from the rest; in T. seticornis, three are distinct
from the remaining two or three, hy the front rows being sunk in a deep
concentric furrow. Other modifications take place. In T. fimbriatus, the
two front rows are turned downwards; lastly in T. ornatus, the dots occur
most frequently in quincunx order."

'In a note on p. 52, Mr. J. W. Salter suggests the new generic name of
Plutonia, but leaves the description for another article.

A species of this genus was afterwards described and figured in the
same journal, vol.27, 1871, pi. 15, figs. 1-8, under the name of Plutonia
sedgivicJci Hicks. This large species has affinities with the genera Para-
doxides and Anopolenus in the form of its glabella, but differs, according to
Hicks, "in having the whole surface covered with coarse tubercles or
spines." The term Plutonia is objectionable, inasmuch as it was used in
1864 for a genus of the MoUusca.

Angelin describes and illustrates Ampyx costatus Boeck, taking Sars'
figure of Ampjyx mammiUatus, pi. 8, figs. 4 a-b and d, for the type of the
species. On comparing Angelin's illustrations of Ampyx costatus, lA. 40,
fig. 1, we observe that they resemble Sars' figure, pi. 8, fig. 4 b, in having
a produced glabella and spine. Sars' figures given on pi. 8, fig. 4 a, rep-
resent a species with a blunt glabella terminating in a tubercle; fig. 4 b of
the same plate has an extended glabella prolonged into a spine. Both
these figures do not appear to be the same, therefore Angelin's description
of Ampyx costatus shoiild be confined to Sars' fig. 4 b, and Ampyx mam-
millatus should be restricted to Sars' figures of this species given on pi. 8,
figs. 4 a~c.

These illustrations do not quite coincide, but they agree much better
than fig. 4 b. That both Boeck and Angelin were correct in splitting up
Ampyx mammiUatus Sars there can be no doubt; it is a question of the
correct separation. Ampyx costatus should not include the spined and
non-spined glabella represented on Sars' pi. 8, figs. 4 a-b, as Angelin has
reclassified it.

Account of some fossil Crustacea which occur

in the coal formation (Argas).

In Record of Geol. Sci. (Thomson's), vol. 1. 1835, p. 1.36.

According to Capt. J. E. Portlock (Rep. Geol. Londonderry, etc., 1843,
p. 313), " Dr. John Scouler first noticed this remarkable Crustacean found
by him in the Carboniferous strata of Paisley; and, depending as a prin-
cipal character on the lateral caudal appendages, he pointed out its analogy
to the genera Cyclops and Ap^is. And again, at the meeting of the British
Association at Glasgow, he described two species, one of which, Argas
tricornis, in all probability depends on an illusive appearance produced by
the overlapping of the crust of different individuals. * « " Di-. .John
Scouler having subsequently altered his view of the affinities of the genus,
he now considers it a bivalved Crustacean, distinguished by not being
able to retract the tail within the shell, and hence has named it Dithyro-
caris, or bivalved shrimp, abandoning the original name as one already
preoccuijied."

The Rep. 10th Meeting Brit. Assoc. Adv. Sci., 1840, held at Glasgow,
does not contain in the index Dr. Scouler's name or that of the genus
Argas or Dithyrocarts. In the 5th Rep. of the "Committee on the Fossil
Phyllopoda of the Palasozoic Rocks," 1887, the genus Dithyrocarls Scouler
is quoted on the authority of Captain Portlock as follows: ^'Diihyrocaris

In the 5th Rep. to the Brit. Assoc. Adv. Sci., 1887, on the fossil Phyl-
lopoda by the committee, consisting of Mr. R. Etheridge, Dr. H. Wood-
ward and Prof. T. Rupert Jones, this new genus of S. H. Scudder is referred
to as probably that of Dithyrocaris Scouler, 1843.

chiefly by the labors of M. Sjogren.

The Paradoxides beds are divided by him into two divisions, of which
the lowest consists of arenaceous flagstones — this is characterized by
Paradoxides tessini; the upper consisting of greenish shale with inter-
calated calcareous and arenaceous beds with Paradoxides ulandicus. The
strata with P. /orc/iAa?nmer/ (that there occurs) making a third division.
They are immediately overlain by the Olenus beds.

The name Estheria was originally proposed by Dr. Kiippell for a species
brought from Abyssinia; its description, with figures of typical species,
apiieared in the above cited work. In the same year Mr. Audoin (Annales
Soc. Eutom., vol. 6), proposed that of Cijzkus for similar species, without
a generic description. Th'e simultaneous publication of these two generic
names for the same geniis lead Mr. Joly (Annales Sci. Nat., 2d series, vol.
17, 1842, p. 293), to propose that of Isaura.

Estheria is now generally used by aiithors.

The author divides the Agnosti into four groups, as follows:

Longifroutes: This section is distinguished by its strongly projecting
glabella and axis, which is usually moderately long. Crust smooth. The
cheeks grooved. The shell on both the cheeks and tail is provided with
elevated granulations. Limb is generally narrow. The cheeks in front
of the glabella, and side lobes of the tail behind the axis, are divided by a
groove.

leatus Aug., A. reticulatus Aug., A. trlsectus Salt., .4. pisiformis Linne, A.
cyclopyge n. sp., A. pusillus n. sp.

2. Lretvigati: The dorsal groove outlining the glabella and axis of the
thorax are obsolete. Crust smooth and shining, sometimes with slight
indications of stria^. Limb on the head disappearing; on the ijygidium it
becomes broad.

Agnostus cicer n. sp., A. niidus Beyr., also var. scankus n. var. and var.
marginattis BriJg., .4. glandiformis Aug., A. lavigatus Dalm., ^4. bitiibercu-
latus Aug.

Limbati: General form subquadrate. Head has a broad limb. Basal
lobes are large. The cheeks in front of the glabella are divided by a
central groove, striated on the sides. Pygidium is usually provided with
lateral siiines.

(a) Kegii: Agnostus regins Sjogr., A. rex Barr. This subdivision is
distinguished by its broad limb diminishing cheeks on the head and side
lobes of the tail (esiDecially by the front lobe of the glabella).

(b) Fallaces: This series has a smaller head, moderately broad limb.
Cheeks large. Basal lobe father large, also Ijy the third joint of the tail
which is enlarged.

In this work, publislied in 1793, the Eev. David Ure noticed the exist-
ence of certain " microscopic bivalved shells " in the Carboniferous lime-
stone near Glasgow.

Four or five of these fossils were illustrated aud described. One of
them, pi. 14, fig. 15, is a subreniform Cythcre; fig. 20 is a somewhat
crushed Bairdia; fig. 21 represents a Kirkbya poorlj^ drawn (M. urei

This article also contains an essay on the organs which were found by
Dr. Pander on the under side of the pleurfB of Asaphus, which resemble
very much the feet of Trilobites.

There is also a second paper on the heart of the trilobites. The author
states that he found on an Illrenus from which the shell had been removed
in the region of the axis, on the median line, a small, flat, depressed,
tubular organ, horizontal furrowed and divided into thirteen chambers.
This tube extends from the margin of the pygidium in a curved line to
the glabella. The chambers are all of uniform length— 1 1 mm. The width
enlarges towards the front in such a manner that the first nine chambers
from the pygidium are only U mm., whereas the tenth and eleventh

chambers are 21 to 3 imii. iu width. The anterior charaliers are nearly
double as wide, and they are divided by a transverse furrow (which is
probably a line of fracture) into two equal parts. The thirteenth cham-
ber lies under the glabella.

This article on the new genus Ceralocephala was read before the Western
Academy of Science, May 25, 1838.

The name Ceralocephala was ^jroposed for a fossil from Springfield,
Ohio, well described and illustrated. The original specimen which received
the name of Ceralocephala gonkUa was a large head of a trilobite with
bases of conspicuous spines upon the occiijital ring. The author illus-
trated the fossil in an inverted position and regarded the occipital spines
as antenn;e.

The geuus Otarion was made up from the head of Cyphaspis huroneisteri
Ban"., connected with the pygidinm of Cromus heaumonti Barr. The
second species, described as Otarion? squarrosum, is referred by Barrande
to Cheirurus quenstedti.

Zenker uses two generic names for his new genus Conocephalus, the first
on p. 48 in describing the genus and the second in his description of plate
5, where he calls it Trigonocephalus.

Both these generic terms had been used in natural history for other
genera, the first by Thurnburg in 1812 for a genus of the Orthoptera, and
the second by Oppel in 1811 for the Reptiles.

The typical species described as Conocephalus costatus on p. 49, and also
in the explanation of pi. 5, figs. G-K, p. 51, as Ih'igonocephalus costatus
has been referred by Barrande to an amended genus, Conocephalites (Zenker)
Barr., and the species to the older name of sulzeri. The other new genus,
Ellipsocephalus, has been used by all subsequent authors, the species tak-
ing the older name of Ellipsocephalus hoffi. Schloth.

For the geological horizons the author has used the
term "Cambrian" for the original Cambrian of Sedg-
wick, 1836 (Lower Silurian, Murchison). The term
" Taconic " is used for the zone with the Olenellus, Par-
adoxides, Olenus and Dicellocephalus faunae. " Silurian"
is used for Murchison^s Upper Silurian.

Conformity to the rules governing nomenclature, which are intended

to render justice to every investigator, the genus Atops Emmons,

1844, should replace that of Conocoryphe Corda described in 1847.

The original figure of this species was the first primodial fossil

described from American rocks; this species wiih. Olcncllus asaph-

oides Emm. clearly defined the Taconic System in 1844 and its

position below Murchisou's Lower Silurian of 1837. The fact

that the original Cambrian was the same as the Lower Silurian

cannot be recalled and in jiistice to Sedgwick it must be given to

that system.

The figures of this species given by Dr. Emmous are all imperfect.
Ford's figure given in Bull. U. S. Geol. Survey, No. 30, pi. 27,
fig. 1 a-b, shows a glabella and a pygidium, which is nearly semi-
circular in form; the axis strong, composed of 7 segments, with
a row of obtuse spines along the middle; lateral lobes composed
of 5 segments, each with distinct intervening grooves; marginal
rim uearl}' flat, widest towards the front and distiuctlj' and regu-
larly notched or denticulated all around. This may prove to be
a species of the genus Olenoldes.

we know of no other to which it bears a resemblance, the new
generic term of TAoydia is i)roposed, in honor of the first author
on Trilobites, Edward Lhwyd. Diagnosis: Glabella tumid and
extending to the frontal limb; basal lobes elongate- oval, pointed
at both ends, separated from the glabella by shallow, obscure
grooves; eyes opposite the mid length of the glabella; thorax

LONCHOCEPHALUS Oweu, 1852; Kep. Geol. Survey Wisconsin, Iowa, and
Minnesota, p. 576. Dr. Owen in his report, Geol. Survey, Wis.,
Iowa and Minnesota, described four new genera of trilobites under
the names of Dikelocephalus, Lonchocephaliis, Crepicephalus and
Menocephalus . The second genus is now classed as a synonym
to Anoinocare with Anomocare chippeiocensis, and A. hamulus, de-
scribed in the report. There is a third species mentioned by Owen
on p. 624, and also plate 1 a, fig. 15, Pygidium of Lonchocephaliis
(?) with long, slender, divergent caiidal spines; also a similar
pygidium, figured plate 1 a, fig. 13, as Dikelocephalus (?) ioivensis.
Walcott, Bull. U. S. Geol, Survey, N. 10, p. 36, places the latter
species under a subgenus to PUjchoparia, using Dr. Owen's Crein-
cephalus for it on account of the peculiar pygidium, overlooking,
however, the fact that Owen has referred a similar pj'gidium directly
to his genus Lonchocephalus on p. 624 of his report. Under the
law of priority the geniis Ptychopariaveiilaces Crepicephalus, and
the later name should be cancelled in toto, and not be retained in
a modified sense. Lonchocephalus forms an exception to this
rule, if we divide the genus into two sections, retaining Anomo-
care for hamulus and chippewcensis, and Lonchocephalus for the
species described by Dr. Owen with long, slender, divergent caudal
spines which includes Dikelocejyhalus (?) iowensis.

Shumardia Bill., 1862; Pal. Foss., vol. 1, p. 92. Type, Shumardia granu-
losa Bill., from Point Levis, Quebec.
This generic name suggested for a minute Trilobite includes a speci-
men having an expanding glabella, with two anterior side nodules,
similar to those of Battus pusillus Sars, the genus being allied to
Afjnostus, differing therefrom in having a regularly ribbed py-
gidium, similar to that of an Asaphus. Comparing Shumardia
gramdosa with Conophrys salopiensis Call. (Quart. Jour. Geol. Soc.
Loudon, vol. 33, p. 667, pi. 12, fig. 7), which Brogger (Sil. Etagen
2 und 3, p. 125) refers to as a synonym to Battus pusillus, we find
a similar characteristic in the glabella. The pygidium of Shu-
mardia granulosa has however a more semi-oval form, with a
greater niimber of axis rings and an additional number- of ribs
on the side lolies.

SHUMAKDIA. SOLENOPLEUKA.

The head of Shumardia granulosa differs from Battus pusillus in
having a groove, which runs from the anterior front of the gla-
bella to the frontal margin of the head, a characteristic of some
species of Agnostidit (vid. Brogger, Sil. Etagen 2 und 3, pi. 1,
fig. 10).

Mr. Billings remarks that "in some specimens this furrow has at
the bottom a small triangular tubercle, giving the glabella the
appearance of having a projecting angular process in the middle
of its front." I am more inclined to view this triangular tubercle
as a point of attachment for the muscles of the jaws, and not as
a process for the att-ichmeut of antennae.

Mr. E. Billings in the same book gives a descrij^tion of a second
species, which he calls Shumardia glacialis, figured p. 283, fig.
270. The species is represented with three glabella furrows, and
should not be included in the geniis Shumardia.

If these forms are not embryonic, I would advocate the acceptance
of Shumardia amongst the Agnostidce for such species as Shu-
mardia granulosa Bill, and Battus pusillns Sars to replace the
later generic term of Conophrys Call.

SOLENOPLEURA Aug., 1854; Palasont. Scand., p. 26. Type, Solenopleura
