Palaeozoic Crustacea

The publications and notes on the genera and species
during the past twenty years, 1895-1917

BY

ANTHONY WAYNE VOGDES

The object of this fasiculus is to give all the literature
on the Palaeozoic Crustacea, also a general index to its
contents, with a list of the species and remarks on them.
This will aid the student in his researches and save time
in looking up the descriptions of the species and genera.

The new genus Ceraurinus is like Cheirurus insignis Beyrich in size.
The glabella is subrectangular or expanded only slightly.

The posterior of the 3
pairs of glabellar furrows are straight, about one-third the width of the glabella in
length, and slope gently backwards.

Their inner ends are connected with the neck furrows by curving constrictions,
which are about parallel to the axis of the glabella.

The constrictions are strong in some species and flat in others.

The middle part of the axial portion of the neck furrow is parallel to the posterior
edge of the neck segment.

BIBLIOGRAPHY OF PALAOZOIC CRUSTACEA

BERTO NaC eualele) ae continued,

The author places under the family cheirurinae twenty genera divided into two sec-
tions.

Group 1. Cheirurinae with plural furrow horizontal, thoracic segment rarely 9,
generally with 10 or 12.

Under this group he places:

Eccoptochile Corda, genotype E. claviger Beyr., with figure.

Actinopeltis Corda genotype 4. glohosus Barr, with figure.

Cyrtometopus Angelin genotype C. clavifrons Dal., with figure.

Sphaerexochus Beyrich genotype S§. mirus Beyr., with figure.

Anacheirurus Reed genotype 4. Frederici Salt., with figure.

Pilekia new genus genotype Ch, apollo Bill., with figure in text.

This is an early Ordovician genus unlike the Cheirurinae. The author figures the
glabella, which contracts forwards with three pair of glabellar furrows; pygidium
composed of 4 complete segments and a terminal axial plate, the ribs terminating in
long spines. He refers Ch. gracilis Barr. Cyr. foveolatus Ang. and with doubt Ceraurus
Clintoni Foerste to the genus.

Nieszkowskia Schm. genotype N. cephaloceras Nieszk., with figure.

Kawina new genus genotype Ch. vulcans Bill., fig. of head in text.

The glabella large and composing one-half of the head strongly swollen, and with
a tendency for a faint hump at the posterior. Three pairs of glabellar furrows, facial
suture running almost parallel to the sides of the glabella, and cutting the border at
the genal angles or slightly in towards the axis. Genal angles without spines.

The author refers to this genus Ch. prolificus Bill., Ch. mercurius Bill., Pseudo-
sphaer. Billingsi Raym. and Pseudo-sphaer. approximus Raym.

Pseudosphaerexochus Schm. genotype P. Aemicranium Kut., with figure, includes 11
species. Cheirurus Paronai Airaghi probably belong here, but the author does not in-
clude it.

Placoparia Corda genotype P. Zippei Boeck, with figure.

The author includes also Calymmene tourneminei Rouault, but does not mention
P, cambriensis Hicks.

Area Barr. genotype 4. bohenica Barr., fig. in text.

The author includes 4. Fritschi Barr., but no mention of 4. suecica Olin.

Prosopiscus Salter genotype P. mimus Salt., with figure.

Typhloniscus Salter genotype T. Bainii, figure in text.

Sphaerocoryphe Angelin genotype S. dentata Ang.

This is a Swedish species, the figure 16 in the text after Schmidt, looks more like
S. cranium Schm. pl. 8, fig. 7.

Hemisphaerocoryphe Reed genotype H. pseudo-hemicranium Nieszk., with figure.

This is an intermediate genus between Cyrtometopus and Sphaerocoryphe. From
Cyrtometopus this genus can be distinguished by its highly inflated frontal lobe. From
Sphaerocoryphe it may be distinguished by its obtusely triangular free cheeks and by
its posterior pair of glabellar furrows, which bend sharply backward instead of ex-
tending across the glabella.

The author includes besides the type Metopias aries Eichw. and Cyrt., Rosentali
Schmidt.

Group 2. Cheirurinae with constricted pleurae and with diagonal pleural furrows,
Lehua noy. genotype Ch. vinculum Barr.

The genus resembles Eccoptochile and Anacheirurus. From the former it is most
readily distinguished by: its lack of eyes or, if present, situated far forward, and by
the diagonal pleural furrow, and by the slender spine-like termination of the pleurae.

The author includes besides the type Typhloniscus princeps Reed and Ch. inexpectatus
Barr.

BA RTO N (Donald C.)—Continued

Cheirurus Beyrich genotype Ch. insignis Bevr., with figure.

The genus can be readily distinguished from Ceraurus and Ceraurinus by the tri-
angular basal lobes of the glabella, the inner points of which are not separated by a
portion of the glabella; also by the hypostoma.

Crotalocephalus Salter, genotype C. Sternbergi Boeck. Fig. of head in text.

Ceraurinus Barton, genotype C. marginatus, Fig. in text.

Distinguished from Cheirurus and Ceraurus by the rather large ovate to sub-
rectangular basal glabellar lobes.

Ceraurus Green, genotype C. pleurexanthenus. Fig. in text.

The author does not include Youngia, a genus described by Lindstrom, with Cheiru-
rus trispinous for its type, in 1885—not Youngia, Jones & Kirby, 1886.

The genus has long genal spines with aculate occipital ring, and may be compared
with Nieskkowskia.

Lindstrom genus has a peculiar axis to the thorax, the first axial joint being fur-
nished with a pair of small lateral processes on the anterior margin.

Barbour (EK. H.) Carboniferous EKurypterids of Nebraska.

Am. Jour. Sci., 4th ser., vol. 38, 1914, p. 507, figs. 1 and 2.

The author describes Eurypterus (Anthraconectes) nebraskensis nov., from the Coal
Measures near Peru, Nebraska.

The main features are the vermiform appearance, the long spatulate paddles, and
the spinous ridges upon the last 5 tergites of the post abdomen.

Fig. 2 represents an unnamed sp.

The author gives a review of larval stages of Trilobites.

Analysis of variations in Trilobite larvae.

Antiquity of the Trilobite.

Restoration of the protaspis, etc.

The author remarks in regard to the larval stages cf the following Trilobites from
the Cambrian:

Solenopleura robbi Hartt., after Matthew.

Larva very minute and circular in outline; the glabella is obscurely annulated and
extends to the anterior margin, where it is expanded.

The neck ring is only one, well defined; abdominal portion is less than one-third
the whole length, and is limited by a slight transverse furrow; no traces of eyes or
free cheeks.

Liostracus onangondianus Hartt., after Matthew.

BIBLIOGRAPHY OF PALASOZOTIC CRUSTACEA 9

BEECHER (Charles E.)—Continued

This form is similar to the preceding though larger, and with the glabella more
rapidly expanding in front. The neck segment is the only one which is distinct.

Ptychoparia linnarssoni Walcott, after Matthew.

The axis is narrow, expanding in front, and obscurely ringed; 5 annulations be-
longing to the head and one to the pygidium, which is very short and separated from
the cephalon by a distinct groove.

Ptychoparia kingi Meek.

The author remarks that fig. 6 which is referred to a later stage, shows the incep-
tion of several characters that have not as yet appeared in the previous larvae. ‘The
axis is very strongly annulated; the anterior lobe is nearly as long as the 4 posterior
annulations of the cephalon, and on each side there is a furrow representing the eye
line of the adult; the free cheeks are present as narrow marginal plates including the
genal spines; the pygidium shows 2 segments separated by a furrow.

The author figures Sao hirsuta Barrande, pl. 8, figs. 8-1,

Ordovician species.

Triarthrus becki Green.

Two protaspidan stages of this species have been noticed, differing chiefly in the
size of the pygidium. Both agree in showing a strongly annulated axis, not expanded
in front and terminating some distance within the margin.

Acidaspis tuberculata Conrad.

In general form the larvae resembles those of the second larvae stage of Sao, but
the pygidium is shorter and the glabella does not expand and terminate in the anterior
margin. . No eye-line is present, but the eye lobes may be seen a little within the margin.
The glabella has the characteristic number of annulations: margin provided with a
row of denticles; genal angles extended into spines; pygidium with 4 spines.

The generic term Arges Goldfuss pre-occupied. See Ceratages, Giirich, 1901.

Arges consanguineus Clarke.

As the main details of structure in Acidaspis and Arges are so similar the young
Arges show the same acceleration in the development of the spines and surface orna-
mentation and the retention of the primitive features of the glabella.

Proetus parvisculus Hall.

The illustrations of this species show strongly annulated axis with groove at each
side; large, prominent anterior eyes, pygidial pleura indicated by faint grooves.

Dalmanties socialis Barrande.

The author gives 4 figures of this species.

The anaprotaspis stage showing the large, strongly annulated axis, the prominent
anterior marginal eyes, mucronate genal angles. Pygidium of 3 segments.

The other families have been reclassified by Reed, Walcott and Raymond. Walcott
remarks, in regard to Damesella, that the facial suture cuts the postero-lateral margin
outside of the genal angle, so as to leave the genal angle on the fixed cheeks; the spine

corresponding to the genal spine in other genera of the order Proparia is on the free
cheeks.

Under the new generic name of Olenopsis the author includes a genus which differs
from Olenus in the form of its small, rounded pygidium with an unjointed axis; the head
is semicircular in front and not straight as in Olenus; it has also a conical smooth glabella,
with 14 or 15 thorax segments.

The genus has been referred by Frech Lethaea geognostica, 1 Theil. Lethaea palae-
ozoica, 2 Bd., I Lieferung, p. 41, to Olenellus sub. genus Holmia.

The author describes Olexopsis Bornemanni n. sp., O. Zoppii Menegh., O. longispinatus
n. sp., O. micruroides n. sp., and O,. maximus.

Metadoxides torosus Menegh. n. gen. et sp.

This genus is similar to Paradoxides with numerous thoracic segments and a small
pygidium. ‘The head is short and wide; the front margin nearly straight; the glabella
is similar to that of the Olenidae, and has three oblique furrows, which do not extend
to the center.

Metadoxides armatus Menegh., M. Bornemanui Menegh., M. arenarius n. sp.

Matthew, in Studies on Cambrian Fauna, No. 3, p. 87, classifies the genus Metadoxides
as follows:

1—Species having a widely expanded front to the cephalic shield; somewhat pro-
longed eye lobes; short posterior extension of the dorsal suture. No costae on the side
lobes of the pygidium.

Catadoxides n. subgen., type C. magnificus Matt.

2—Species having a compacted front to the cephalic shield, short eye lobes, prolonged
posterior extension to the dorsal suture.

16 SAN DIEGO SOCIETY OF NATURAL HISTORY

The species of this genus resembles in structure of the thorax those of I/laenus, from
which they differ by the more arched axis, and the side spines of the pygidium.

Under the new generic name of Anthracopeltis, the author describes and _ illustrates
a pygidium as Anthracopeltis Crepini.

The pygidium resembles that of Phaeton Barrande, but may be distinguished by the
shape of the axis, also by a groove which runs around the tail near the base of the
spines.

The reviewer remarks (Schuchert): “It is truly a monumental work and a model
for all paleontologists to follow.”

In this work one can study Eurypterida from any view point permitted the palzon-
tologist. Here we find their chronology, their development from baby stages, pro-
phetic of unknown ancestors, to adults; and their relations to scorpions, horseshoe crabs,
Trilobites and even to hypothetic annelids.

The authors illustrate in text and plates the following species:

Strabops thacheri Beecher.

Eurypterus.

The American species of Eurypterus readily fall into three subdivisions:

(A) Those that grovps themselves around E. remipes.

(B) Those that vary in different directions from this group, but are approximately
contemporary—E. Dekayi, ete.

(C) The later Carbonic species.

Under this genus the authors describe:

Eurypterus remipes DeKay, E. lacustris Harlan, FE. lacustris Hall var. pachychirus
Hall, E. DeKayi Hall, E. maria Clark. This species differs from American congeners,
due to the terete form of the body that apparently is without preabdominal expansion.

New York Devonic as Dalmanites concinna var. serrula in 1888, and referred to
Cryphina serulla.,

The author in view of the known variation between Cryphaeus and Hausmannia
places the new genus with a caudal extensicn in his new genus. ‘The head differs
from that of Cryphaeus. The author describes in addition to the type Calmonia
signifer var. micrischia nov., C. subseciva nov. and C. ocellus Lake, described by Lake
under the genus Phacops from South Africa. C. ? gonzana Clarke.

Pennaia new genus type, P. pauliana nov.

A very distinct variation of the Mesembria type of Dalmanites is expressed by
Pennaia pauliana. In general aspect it is distinctly more Phacopidean than Calmonia,
in respect: first, to the head, in which all parts are more compact and condensed ;
second, in the thorax, where the axis is relatively much broader than the side lobes,
while the ends of the anterior segments are rounded rather than lanceolate; third, in
the pygidium, which is phacopidean in its small size and sparse segmentation. ‘The
margin of the pygidium is fimbriate, bearing three flattened spinules on each side.

Proboloides gen. nov. type. P. cuspidatus and P. pessulus nov.

In the possession of a frontal snout on the head this species is a Probolium after the
type of snouted Dalmanitids, but in respect to the character of the snout, the form of
the cephalon, its style of lobation and smoothness of surface, it departs from the type
and is an expression of the Mesembria structure.

The author proposed the term Phacopina in place of Phacopidella, which Reed uses
for Acaste, a preoccupied term.

Encrinurus silverdalensis, a robust species, about 2 inches long; the head approaches
E. variolarlis, but its enormous tail separates it from the European species.

Encrinurus Etheridgei, the largest Australian form known, has a length of 2%
inches, of which the tail occupies one inch.

Encrinurus Rothwellae.

The subrectangular and steep-sided thorax, very prominent thorax and pygidial axis,
a circular end of the tail—axis, 11 pleural segments in the pygidium, widely expanded
and tumid glabella, anteriorly forward eye-lobes, and strong drooping of the pygidium
posteriorly, separate this species from E. Mitchelli.

Encrinurus 2? duntroonensis.

The authors illustrate only the head, which differs from all other species referred to
Encrinurus.

1. In the transversely elongated elliptical form of the cephalon, with its nearly
straight anterior border.

2. The closeness of the anterior branches of the facial sutures and the perpendicu-
larity of the posterior branches of these, with the axial furrows, or central axial line.

3. The long, narrow and straight-sided glabella.

4. The anteriorly situated free cheek.

Calymmene Niagarensis Hall. ‘This specimen was published in the Jour. Cincinnati

brary did not receive this number until Feb. 19th, 1880, or about the time of its probable

,

publication. About this time, in the Amer. Jour. Sci. for December, 1879, a species was
described by Vogdes as Calymmene rostrata from the Clinton Group of Georgia Catoosa
Station. These forms are very closely related to New York specimens, which are not
quite so large, and the end of the snout is not so pointed as the published figures would
indicate.

Dr. Berjoron, Bull. Soc. Geol. de France, 3d ser., vol. xviii, 1890, p. 365, pl. v, places

The author favors the use of Cryptolithus Green, for the genus Trinucleus, a generic
term used by Bronn, Goldfuss, Emmrich, Angelin and Vogdes; although the generic
name of Nuttainia was used by Eaton in 1832, in his Geological Text Book, 1832, p.
33, for a similar species to Trinucleus tessellatus Green.

The original description of this genus by Green, The Monthly American Journal of
Geology, June, 1832, p. 560, pl. fig. 4, is as follows:

Genus Cryptolithus, C. Tessellatus Green, fig. 4.

“Clypeo rotundato, fronte valde convexo, capite antice semicirculari, margine tessellato,
ornato.”

Green Mon. Trilobites, p. 88, remarks Cryptolithus was proposed before the publi-
cation of Nuttainia Eaton.

Rafinesque in his paper dated Philadelphia, May, 1832, Atlantic Journal and Friend
to Knowledge, vol. 1, No. 2, 1832, article on “The Genera of fossil Trilobites or
Glomerites of N. America,’ mentioned Cryptolithes Green, on p. 72, and remarks that
Dr. Green issued in April a first series of eight cast and species, accompanied with a
synoptical table, among which a new genus Dipleura, and four new species of Asaphus
and Calymmene.

Vogdes, in Bib. Paleozoic Crustacea, 1893, p. 359, remarks that Trinucleus Lhwyd,
1698, Lithophyacii Brittanuici Ichnographia, Epistola 1, also Murchison Silurian Sys-
tem, 1839, p. 659, was a revived old name. Dr. Lhwyd’s description meant no more
than the general name of Trilobite of the more modern writers and could not, except
by courtesy, set aside Dr. Jacob Green’s gen. Cryptolithus. This generic name has been
advocated by Foerste, also by Raymond, in a later publication.

The author also describes Calymmene platycephala sp. nov., C. senaria Conrad, C.
abbreviata sp. nov., C. callicephala Green, C. Meeki sp. nov., C. Meeki—retrorsa and

The author gives a figure of Prolimulus HWoodwardi on p. 58, and remarks that
Prolimulus very closely resembles one of the embryonic stages of the living North
American Limulus polyphaemus. ‘The earliest known Limuloid Crustacean named
Neolimulus falcatus, Woodward Geol. Mag., vol. 5, p. 1, pl. 1, figs. 1, la, 1868, was
from the Silurian of Lesmahagow, Scotland. Bailey described Bellinurus Kiltorkensts
from the Upper Old Red Sandstone Kiltorcan, Ireland, in 1869.

The genus Bellinurus was established by Konig in 1825, for certain small king
crabs, under the specific name of B. bellulus, without a description of the genus or
species. It is now known as Bellinurus lumatus Martin Petrefacata Derbiensia, pl. 45,

Anitopyge is similar to Cheiropyge (a new genus described by Diener of Himalayan
fossils) in the unequal segmentation of the axial and lateral portions of the pygidium—
in Anisopyge the pygidium is surrounded by a broad, smooth band, while in Cheiropyge
the lobes are extended so as to give this member a denticulate outline.

Harlani Green.

The author remarks that among the American relative of Paradonicvs Harlani the
most nearly related to the broad form is P. regini Matthew, from St. John Group;
also P. Bennetti Salt.

The nearest relative of the narrow form is the Paradoxides spinosus the Bohemian
species. Many years ago Linne Mus. Tessiniaum, 1753, p. 98, pl. 3, described under
the name of Entomolithus paradoxus a trilobite of a wide form, about 634 inches long.
Brongniart describes it as Paradoxides Tessini, using the narra form of Wahlen-
berg’s pl. 1, fig. 1, which he has copied.

The original, quoted from Dimbo, Sweden, by Linné, has never been again found
in Sweden, the specimen may be one from Boston, Mass., cbtained from the Boston
Wharves by some Swedish naturalist in early days, the stones from the Braintree quar-
ries were used in the Boston Harbor.

The conformation of the head suggest Trinucleoid afhnites, but there is no marginal
rim, and the rest of the body appears to show Olinid characters. Shumardia is pos-
sibly an ally, but the new genus differs in the extension of the glabella to the front
margin of the head, in the absence of glabella furrows, and in the spinous prolonga-
tion of the thoracic pleurae.

of Encrinurus expansus. This species is broadly ovate, length about one and one-
fourth of an inch; breadth two-thirds of the length, cephalic shield, semi-circular
tuberculated posterior angles rounded; the glabella pear-shaped, convex, and covered
with tubercles, and punctured between the tubercles; large tubercles, occupying the
place of lateral lobes; cheeks triangular convex and embracing the front of the glabella;
eyes pedunculated and placed between the centre of the cheek; and the glabella obovate
and covered with a fine net work of facets.

Baltic and American forms were only geographical variations arising through migra-
tion. With this idea Clarke and Ruedemann have concurred.

Shales.

Brit. Assoc. Ady. Science, 83 Ann. Meeting, Sec. C, 1913.

Abstract in Geol. Mag., Dec. V, vol. 10, p. 452, 1913.

The author remarks that among the fossils found at Hartshill Hayes, numerous
forms occur, representing young stages in the development of certain Trilobites. Among
these are the following:

1. Liostracus sp., similar to one described by G. F. Matthew.

2. Holocephalina sp. The early stages of this genus possess a well-marked glabella,
widening anteriorly.

3. Paradoxides Hicksii,

4. Certain new forms of Agnostus.

The author proposed Paragnostus with dgvostus rex as its type. This was the type
of Corda’s Condylopyge. He further proposed Dichagnostus with 4 gnostus granulatus
as the type duplicating Corda’s Pleuroctenium. ‘The author gives the name of Mesag-
nostus for A. integer Beyr., which was used for Corda’s genus Peronopsis.

Miagnostus Jackel has the same type species, 4. /aevigatus Dalm., as Lejopyge Corda.
The new genus Leiagnostus, which has the same generic characters as Phalocroma
Corda.

Metagnostus erraticus and A. glabratus have the same short glabella with faint
basal lobes as Agnostus tardus Barr., which was the type of Corda’s Arthrorhachis.

Vogdes, in Am. Geol., vol. 9, 1892, p. 395, in his paper on North American species
of the genus Agnostus, uses this term for section IV.

The author arranges the families as follows:

1. Fam. Paragnostidae. Paragnostus n. gen., type 4. rex Barr.

Dichagnostus n. gen., type 4. granulatus Barr.

Diplagnostus, type 4. planicauda Ang.

Mesagnostus n. gen., type 4. integer Barr,

Lake (Philp). On the British species of Acidaspis.
Quart. Jour. Geol. Soc. London, vol. 52, pp. 235-245, plates 7-8.
The author describes and illustrates the following species:

Acidaspis Brighti Murch., 4. coronata Salter, A. deflexa n. sp., A. crenata Emm.,
A, quinquespinosa Salt. MS., 4. Barrande: Fletcher & Salter non Angelin, 4. Hughesi
Salt. MS., 4. erinaceous Marr & Nicholson, 4. callipareos Wyv. Thomson.

The author remarks the British species which have been described have in many
cases been imperfectly figured, and the result is endless confusion,

The common English trilobite Acidaspis coronata has received abroad no less than
three names, all of them different from ours. In England the foreign name A cidaspis
crenata is often applied to a species which is quite distinct from the original A cidas pis
crenata.

The author remarks in regard to the synonymy of Acidaspis coronata that it is
known in England by the name of 4. coronata, as A. Marklini in Sweden, and 4.
mutica in Germany; Murchison’s term quadrimucronatus is older than any of them.

Even the name of the genus itself is matter of controversy. Murchison’s Silurian
System, p. 653, employed the term Acidaspis, and in the same year Emmrich, De Tril.
Diss. inaug., p. 53, proposed the name Odontopleura. This controversy depends on the
publication of Murchison’s and Emmrich’s terms Acidaspis and Odontopleura.

A copy of Murchison’s Silurian System was presented to the Geological Society
London, Jan. 9, 1839. This would indicate that the book was published early in Janu-
ary, 1839. Captain Portlock, in his address delivered at the 8th annual meeting, Geo-
logical Society of Dublin, Feb. 14, 1839, remarks he had been favored with a copy of
the work in sheets, prior to its general publication. Jour. Geol. Soc. Dublin, vol. 2, pt.
1, 1839, p. 29.

Emmrich’s paper bears the date, April, 1839.

There is, however, an earlier name still, the use of which has been advocated by
Vogdes (Proc. Nat. Sci. Phila., 1877, p. 138); also afterwards by Clarke (10th Rep.
N. Y. State Geologist, 1891, p. 61). ‘Chis name is Ceratocephala Warder (Am. Jour.
Sci., vol. 34, 1838, p. 377). Dr. Lake remarks that “even if its rival be eligible,
Acidaspis has been so widely used for so long a time that here at least I do not pro-
pose to adopt any other.”

Part 4, pp. 65-88, plates vii-x, Paleontographical Society, 1912.

The author describes and illustrates Parabolinella caesa nov.; compares it with P.
ailliamsoni, to which it is closely allied.

Parabolinella rugosa Brogger var., P. trierthra Callaway, described by that author
under the genus Olenus in 1877.

Triarthrus shinetonensis Raw. The species named by Raw, Rep. Brit. Assoc. for
1907, p. 512, without a description or figure.

The author compares it with T. sfizosus Billings.

Dr. Ami, Trans. Ottawa Field Nat., vol. 1, No. 4, 1882-83, indicates that Triarthrus
spinosus Billings, had spines on the 8th to 13th segment of the thorax. The English
species has 14 segments in the thorax, with the 12th axis ring spined.

Genus Spherephthalmus Angelin.

The author remarks that the genera Leptoplastus, Spherophthalmus, Ctenopyge and
Eurycare, form a natural group of the Olenidae, characterized by the fact, that the
cheek spines do not spring from the posterior angles of the head, but from the middle
of the external margin or even from the lateral angles.

Brogger considers that all these forms should be placed in a single genus, which he
calls Leptoplastus, divided into four subgenera.

The author describes Sphaerophthalmus alatus Boeck. This species is the same as
Olenus humilis Phillips, 1848, according to Linnarsson’s investigations of original
specimen.

Sphaerophthalmus major nov.

Ctenopyge: The author does not agree with Brogger and Moberg that only the axial
rings are fused, while the pleurae are free. The pleurae seem to be closely connected
and rarely show any signs of separation.

The author describes Ctenopyge fusiformis nov., C. bisulcatus Phillips. Salter,
taking Angelin’s Sph. alatus figure as his guide, indicating it with Olenus bisulcatus
Phillips; therefore this species in English publications means Ctenopyge bisulcata or
some similar form. Ctenopyge falcifera nov., C. pecten Salter, C. expansa Salter, C.
teretifrons Angelin, described under the generic name of Sphaerophthalmus.

Lapworth (Charles). On the discovery of the Olenellus fauna in
the Lower Cambrian Rocks of Britain.

Geol. Mag. Dec. 3, vol. 5, 1888, p. 484; also p.190, vol. 6, 1889.

The author remarks: ‘The remarkable fauna of the Olenellus or lowest Cambrian
zone originally discovered in America by Dr. Emmons in 1844 (the ‘Taconic system
based on observations in New York, Massachusetts, Maine, Vermont and Rhode
Island, Albany, 1844, p. 21, Elliptocephala asaphoides,) was first recognized in Europe
by the late Dr. Linnarsson in 1871 (Ofversigt af Kongl. Vetenskaps Akad. Forhandl,
No. 3, p. 790, Paradoxides Kyjerulfi), in the basal zones of the Cambrian near Lake
Mosen in Norway, but its typical genus Olenetlus was then referred by him to the
allied but more recent genus Paradoxides.

This reference was corrected by Prof. Brogger in 1875 (Geol. Forening Stockholm
Forhandl., vol. 2, 1875, p. 573), and the various brilliant papers on the primoidilal
formations by this author have given the Olenellus fauna a marked and peculiar in-
terest.

In 1882 Linnarsson next made known the existence of the Olenellus fauna in Scania
at the base of the Swedish Cambrian. In 1886 the same fauna was detected by
Mickwitz in the Lower Cambrian of Russia (Esthonia) and this Russian fauna has
been lately figured and described by Dr. Schmidt. Dr. Holm has signalized the ex-
istence of the Olenellus fauna in the Cambrian of Lapland, where it was detected by
Morstell in, 1885.

The original discovery of the Olenellus zone in Europe was made by Dr. A. G.
Nathorst in 1868. This species, Olenellus Kyjerulf, was named Paradoxides Wahlen-
bergi, Yorell Petrefacta Suecana from Cambrica, 1869-70, p. 4, but he did not describe
or figure the new form; therefore, O. Kyjerulf must be retained for the name of the
species.

genus Eurypterus, three to Stylonurus, and makes a new species of Silmonia. He is
compelled to make two new genera to receive some more generalized forms. One of
these, Drepanopterus, comprising three species, combines characters found in Stylonurus
and Eurypterus; and for one species with very generalized characters he makes the
genus Bembicosoma.

Researches on the visual organs of the Trilobites.

Kongl. Svenska Vetenskaps Akad. Handlingar Bandet 34, No. 8, 1901.

Dr. Lindstrom considers certain nodes on the hypostoma to be visual organs. ‘This
is based on the discovery of Dr. Liljevall from the hypostoma of Bronteus polyactin
Ang. They are located on the inferior edge of the upper groove, close to the lateral
margins. ‘To these tubercles he gives the name of “maculae”. They are oblong or
ellipsoid; their inferior apices bluntly pointed or rounded, two-thirds of their surface
is perfectly smooth or glossy, and the lower one-third covered with a compact accumu-
lation of small granules, similar to the facets of the compound eyes of Trilobites. The
author, therefore, assumes that they are a pair of small adventive eyes on the exterior
side of the hypostoma, from the perfect structural agreement between them and the
eyes of the head. The author sums up the literature on blind trilobites without facial
ridge; also those with facial ridge, and illustrates the maculae on the hypostoma of
39 genera and 136 species.

The different genera are divided into six groups as follows:

Group 1—In the sectioned maculae there is no tract of any structure. The test of
the maculae considerably thinner than that of the hypostoma. According to the affnites
of the genera they may be subdivided as follows. a—Bumastus, Dysplanus. b—

Nileus, Symphysurus,? Ogygia. c—Calymmene, Homalonotus. d—Cheirurus pro

Group 2—The whole maculae is of a spongious or irregularly polyhedric structure
showing prisms in vertical sections. Asaphus, Isotelus, Megalaspis, Ptychopyge, Niobe?
Megalaspides? Barrandia, Illaenus Lichas, Trochurus? Platymetopus Encrinurus also
probably belongs to this group.

Group 3—Maculae with well-developed globular lens on the interior third of the
maculae; the blank part of the maculae without any structure. In such species as
Cheirurus spinulosus the whole maculae covered with lenses. Bronteus, Cheirurus

Group 5—The elongate, straight maculae, carrying on their innermost point from
3 to 5 diminutive segregate ocelli, situated on a clear, white patch. Proetus. ‘These
ocelli have not been observed on the related genera Cyphaspis, P/aetonides, Phillipsia
and Griffithides, but they may be preliminarly ranked here in consequence of their
close conformity.

Group 6—The maculae have in this group been reduced to a pair of tiny ocelli,
situated high up on the hypostoma, near its anterior margin. Phacops, (caste.

The author attaches classificatory importance to the minute structure and_ super-
ficial ornamentation of the test, which has led him to change the generic allocation of
many well known species, and to institute many new genera.

Lorenz, on account of the different structure or ornamentation of the test, divides
the group Conocephalites into two genera: Conocephalina and Concephalites, but the
type C. Emmrichi Barr. of the latter he puts into the former, thereby making needless
confusion. Conocephalina Brégger has as its type C. ornata Broégger, and the author
has referred to it several English species placed by Salter in Conocephalites, such as
C. invita.

The author illustrates Ptychoparia striata Fm. and places the genus Solenopleura as
a synonym to Ptychoparia, figuring Solenopleura brachymetopus Angelin.

*The author remarks in regard to the new genus Lioparia, that it has medium-sized
eyes, in common with both Ptychoparia and Liostracus; likewise the deep dorsal fur-
row of Ptychoparia. In relation to the shell structure and the flat selvage, it is on
the side of Liostracus. On careful consideration one must admit that Liostracus is in
closer relation to the species Lioparia, than that of the genus Ptychoparia.

He refers Conocephalites minutus Hall to the genus, and uses Lioparia latelimbatum
Dames, with one new species, L. blautoeides, as the type of the genus.

Trachyostracus new genus: Is distinguished by medium-sized wide-apart eyes, flat
selvage and little or no dorsal furrows. In its outer form it is not to be distinguished
from Liostracus. The difference in the genera lies alone in the different shell struc-

ture. ‘Trachyostracus has a thick, rough shell; Liostracus a smooth, finely porous shell.
These two genera exhibit a rare case of convergence.

Examples of this species are the two following forms: Solenopleura Howleyi Wale.
and Ptychoparia limbata Matt.

Under Liostracus Angelin, as emend. by Brogger, the author includes Liostracus
microphthalmus Ang., fig. 4. Ptychoparia Piochensis Walcott. Anomocare planum
Dames. Liostracus Linnarssoni Brogger, L. aculeatus Ang.

Macrotoxus n. gen.: ‘The principal characteristics consist in the very long arch-
shaped eyes, the deep dorsal furrows and the thick, rough shell. The author refers
Anomocare Angelini Groénwall and Conocephalites perseus Hall to the genus.

Alokistocare new genus: This genus has in common with Macrotoxus the long,
arch-shaped eyes, and the long dorsal furrow around the glabella. By its porous shell
it is differentiated from the former. ‘The author refers Ptychoparia subcornata H. &
W. to this genus.

Megalophthalmus nev genus: Also here are the long, arch-shaped eyes the prin-
cipal element. The glabella does not lie deeply in the head shield, but comes out high
over the cheeks. Even trace of dorsal furrows is lacking. ‘The shell is thick, rough,
not porous.

The author refers Liostracus megalurus Dames and Anomocare minus Dames to
this new genus, remarking that it is not improbable that this group is also distributed
in North America. In its external appearance it resembles throughout the old Swedish
species of Anomocare. The last, however, has a highly porous shell.

Under the genus Anomocare the author includes dnomocare latelimbatum Dames,
A. excavatum Ang. A. limbatum Ang. Liostracus Maydelli Schmidt, Anomocare
commune n. sp. and 4. laeve Ang.

The author places Conocephalina Brogger and Conocephalites Barrande, under two
groups, on the difference of the ornamentation of the test, using Ptychoparia Emmrichi
for the type of the first genus, with granulated shell; and Concephalites ornatus Brog-
ger for the second genus, although Brégger used this for his type.

The author figures Ptychoparia Emmrichi Barr. also Conocephalites ornatus Brogger
and C. suecicus Wallerius.

The author gives the following description of the new genus dAmphoton with the
species 4. Steinnanni for its type:

Glabella narrow, highly cylindrical, with deep furrows. On both sides of the high
glabella wing-shaped, similuna-shaped cushions, that resemble ears on a great ele-
phant head. ‘The eyes are long, box-shaped and stand upright. The anterior eye
corners lie close to the glabella. The facial sutures follow the eye lobes, diverging
slightly from the anterior eye corners to the frontal margin. From the rear eye cor-
hers it branched outwardly into a horizontal piece before it cuts through the rear
margin; thereby forms a small band attached to the rear of the cheek. Close to the
front end of the glabella is a narrow, flat, bent-up edge. The pygidium greatly re-
sembles that of Anomocare, for in a slab of fossils from Laiwa, are found numerous
head shields of this species, corresponding to head and tail shields of Anomocare. —

On page 91, the author describes zomocare commune n. sp. (referred by Walcott to
Anomocarella chinensis Walcott); also Anomocare ovatum n. sp. and A. speciosum n.
sp. (referred by Walcott to the genus Anomocarella).

The author includes a description of Olenus sp. Ptychoparia (Solenopleura) sp., and
the description of a new genus Schantungia, with §. Buchruckeri for its type (this has
been referred by Walcott to Chuangia nitida).

The other fossil crustacea described in this work are: Schantungi Monkei n. sp.
Liostracus latus n. sp. Agnostus fallax Linrs. var, Laiauensis n. var., A. parvifrons

An abstract of this paper was published by Woodward in Geol. Mag., Dec. v, vol. 2,
1905, pp. 211 and 251, with a plate.

The author remarks: Drepanura Ketteleri Monke (like D. Premesnili Berg.) is
founded upon detached pygidia, and separate and imperfect head shields; it also has
elongated cheek-spines, which remind one of the very long lateral cheek and caudal
spines of Bathynotus holopyga Hall, from the Lower Cambrian of Vermont.

Woodward refers Stephanocare Richthofeni Monke to Meek’s genus Olenoides.

The following species and genera are described by Monke: 4 gnostus Koerferi n. sp.
Liostracina Krausei n. gen. et n. sp. Teinistion Lansi n. gen. et sp., T. Sodeni nov.
Drepanura Premesnilli Berg., D. Ketteleri n. sp. Stephanocare Gichthofeni n. gen. et sp.
Stephanocare Sinense Berg.

The following species, described by Walcott, Proc. Natl. Mus., vol. 29, 1905, are
synonyms: Ptychopariaceus Walc. syn. of Liostracina Krausei Monke. Dorypygella typi-
calis Wale. syn. of Teinistion Lansi Monke. Damesella chione Walc., syn. of Stephan-
ocare Richthofeni Monke. Teinistion Lansi Morvke is similar to Shantungia spinifera
Walc., but differs in the presence of an incurved frontal margin and the absence of the
long frontal spine.

The conclusion reached by the author, after the study of all the available data, is
that the Eurypterids throughout their entire phylogenetic history lived in the rivers.
Schuchert in the earliest fresh water Arthropods, 1916, remarks that Eurypterids were
marine animals previous to the Devonian, and that towards the close of the Silurian
they became Eurhaline, or able to live in both salt and brackish water, and after
Silurian time they probably became wholly restricted to the fresh water. Proc. Natl.

Refers the Trilobites to a separate class, and regards them as being an older, more
primitive group than the Crustacea. Hence, the Trilobites probably were the first to

originate from the annelid worms, while the crustacea arose by a separate line of
descent.

The authors describe the following Fossil] Crustacae:

Trilobita: Cryphaspis Stephanophara Hall. Homalonotus DeKayi Green. Phacops
rana Gr., P. cristata Hall and var. pipa Hall.

Dalmanites (Cryphaeus) Boothi Gr.

The genus Cryphaspis was proposed by Dr. Green for certain Devonian Trilobites,
in 1837, Am. Jour. Sci, vol. 32, 1837, p. 343, with figures of the genotype Cryphaeus
Boothi and C. calliteles.

The term was pre-occupied for the Coleoptera in 1833.

Burmeister Org. Tril, 1843, under his sub-group Phacops, in which the pygidium
has long spines on its circumference, classes Asaphus archnoides Goldf., a similar
species, under Phacops. ‘This species is now referred to Cryphaeus punctatus Steininger,
1831.

Milne Edwards Hist. Nat. Crust., vol. 3, 1840, pl. 34, fig. 8, copies Hoeninghaus’s
figure of Calymmene archnoides, 1833, and refers it to his new genus Pleuracanthus, at
this time pre-occupied by Agassiz and Gray for fossil fish, 1832.

Corda Mong., Bohm Tril, 1847, p. 242, pl. 6, fig. 67, uses the term Metacanthus for
Phacops stellifer Burmiester, and that of Asteropyge, on p. 241, with Calymmene
arachnoides Goldf. as the genotype.

All the species described under Cryphaeus Green should take the generic name of
Asteropyge Corda.

In the European species of this genus the terminal spine upon the pygidium generally
exceeds in length all of the five marginai spines on each side.

RAYMOND (Percy E)—Continued

genus the glabella does not reach to the front of the cephalon, nor does it expand to-
wards the front; it has also almost obsolete neck and dorsal furrows with a long and
narrow form.

The author takes [soteloides Whitfeldi for the type. This species is the Asaphalus
canalis Whitfield, Bull. Am. Mus., vol. 1, p. 336, pl. 34, f. 1-8, not that of Conrad or
Hall.

Hall credits the name to Conrad in MSS. and figures the hypostoma and doublure
from Chazy Village, New York. This is probably what is now known as Isotelus Harrisi
Raymond.

On account of the facial suture termination at a point in the middle of the anterior
margin, the author classes as Isoteliform suture the genera Asaphellus, Asaphus and
Tsotelus.

In Niobe the suture cuts the anterior margin in front of the eyes, and follows around
the frontal margin, as in Nileus; classed as the Niebiform suture.

The genera with forked hypostoma and with Isoteliform suture are arranged:

Asaphidae—Asaphus, Onchometopus Ptychopyge, Isoteloides and Isotelus. Basilicus
is the only member with Niobiform suture. This form is common with the undivided
hypostoma as in Ogygia, Ptychochei!us, Asaphelina, Niobe, Symphysurus, Illaenurus,
Nileus Barrande, Homalopteon and Platypeltis.

A few genera with undivided hypostoma have Isoteliform suture, namely: Megal-
aspis, Megalaspides and Asaphellus.

The author describes Asaphellus gyracanthus n. sp. (Asaphus canalis Cleland), A.
monticola. Subgenus to Niobe, Hemigyraspis n. gen. ‘This genus is proposed with
Asaphus affinis McCoy as a type. H. collieana n. sp.

The author includes Ogygia desiderata Barr. Niobe menapiensis Hicks, and N.
solvensis Hicks. Asaphellus planus Matt. in the genus.

Megalaspis and Megalaspides.

Asaphidae, hypostoma forked.

The author describes and figures Asaphus marginalis Hall, under the genus Basi-
licus, including as the young of this species dsaphus alpha and A. gamma Raymond.
The author remarks that the species is closely allied to Basilicus tyrannus Murch.

The pygidium figured shows two lobes somewhat similar to that of Dicellocephalina

and much more elevated eyes, and deeper dorsal furrows.

tinct types.

Pointed behind, Megalaspis and Ogygiocaris.

Quadrate, Niobe insignis.

Extended behind into two long, large prongs, Asaphus, Isotelus, ete. He remarks
under the Geologic range, that the Asaphids appear earlier in America and have a
longer range than in any other country.

The Cambrian, which have entire hypostomas, consists of the genera Ogygopsis,
Illaenurus, Symphysurus, Asaphellus, Hemigyraspis and Megalaspis.

Qrdovican, Beekmantown, the Asaphids are less varied as only Isoteloides and
Nileus are present.

In the Chazy, Isotelus, Isoteloides, Basilicus, Onchometopsus, Vogdesia and Nileus
occur.

In the Silurian, in the Lowville (Silurian) and Back River (Ordovian), the genera
Onchometopus, Isotelus, Isoteloides, Basilicus and Vogdesia.

In the Trenton there are, so tar as is now known, only Isotelus and Isoteloides.

In the Utica, Isotelus and Ogygites.

In the Richmond, Isotelus, Onchometopus, Brachyaspis and probably Ogygites.

The author uses dsaphus expansus as the type of the genus, which is characterized
by its short, broad head, and pygidium from which all depressed borders are absent;
by the rather prominent glabella, which expands towards the front and reaches the
anterior margin; the large eyes; the course of the anterior portion of the frontal suture,
which meets in a point in front of the eye; and the short pygidium, with narrow, well-
defined axial lobe and smooth pleural lobes.

The genus is well developed in the Baltic Region.

Under the heading of lines of development from the Asaphus, the author remarks
that the variation in the Ordovician Baltic species seems to be in the direction of the
obliteration of furrows on the surface; that is a further loss of evidence of original
segmentation in cephalon and pygidium.

Onchometopus differs from Asaphus, in having the glabella less marked, the axial
lobe of the thorax wider, the thoracic segments flatter, the axial lobe of the pygidium
less convex and without rings.

Megalaspides, like Asaphus, with narrow axial lobe, expanding glabella, no de-
pressed border on the pygidium, but with a narrow one on the front of the cephalon.

Isoteloides, in which both the cephalon and pygidium have depressed borders.

Isotelus, in which the axial lobe of the thorax is wide, the glabella and the axial
lobe of the pygidium so ill-defined as to merge into the general surface of the head;
therefore, both these smooth trilobites and species of Brachyaspis and Onchometopus
are so like Isotelus, that the three genera can only be separated by their lines of de-
velopment.

Basilicus is a primitive genus, with forked hypostoma, with a strongly ribbed tail;
the facial suture marginal in front, and the glabella strongly outlined and shows
glabella furrows.

The author remarks from Basilicus, Ogygites seems to have developed.

Tromelin and Lebesconte, Assoc. Francaise, Adv. Sci., 1875, p. 33, use the new generic
name of Ogygites for Brongniart’s Ogygia, it having been used for other genera in
natural history. These authors use O. Desmaresti Brog. for the type, and include O.
Brongniarti Rou. as a syn. The same authors refer Ogygia, the first species described
under the genus by Brongniart, to the genus Asaphus.

The author considers Pseudoasphus Schmidt as the next step in the development from
Basilicus and Ogygites.

The author is in error in his remarks that Brongniart applied the name of Ogygia
to O. buchii and O. dilatata with forked hypostoma. Brongniart applied the name to
an Asaphus. The second species described by Brongniart, according to Tromelin and
Lebesconte, bid, p. 34, has the entire hypostoma characteristic of O. desiderata Barr.

Some changes in the names of genera of Trilobites.
The Ottawa Naturalist, vol. 26, Feb., 1913.
The author remarks on the ten new genera described by Jaekel in Zeit. d. Deutsch

Geol. Ges., vol. 61, pp. 380-401, 1909, should be rejected and referred to older names
as follows:

Paragnostus to Condylopyge Corda, Dichagnostus to Pleuroctenium Corda, Mesag-
nostus to Peronopsis Corda, Miagnostus to Lejopyge Corda, Leiagnostus to Plhialacroma
Corda, Metagnostus to Arthrorhachis Corda. These six new genera the author rejects.

The author would reject Microdiscus Emmons, because it was founded on a young
specimen of the genus Trinucleus, and substitutes Eodiscus. This would overlook
Salter’s Microdiscus—the generic name should read Microdiscus Salter (not Emmons).

Raymond, who examined the type specimen of Pemphigaspis bullata Hall, does not
place it with Microdiscus, as suggested by Walcott.

The author is in favor of using Green’s generic name Cryptolithus for Murchison’s
genus Trinucleus. This generic name has long been used by Bronn, Goldfuss, Emm-
rich, Angelin, Foerste and Vogdes. Eaton’s genus Nuttainia of 1832 not used. Dr.
Jacob Green claimed priority in his Monograph of Trilobites. The generic name was
first described in Am. Jour. Geol., June, 1832.

The author uses Ogygites, Tromelin and Lebesconte, for primitive Asaphinae, with
annulated pygidia and forked hypostomata, and Ogygiocaris Angelin, for Ogygia
Buchi and O. dilatata.

The author favors the adoption of Goldius for Brontes and Bronteus. For Acaste
Goldfuss, the author takes the generic name Phacopidella. Reed, 1906, as Leach in
1811, used the first genus for a genus of Cirripedes. Arges was used by Haan in
1835, and the author uses Ceratarges Gurich, for the generic name; also Aulacopleura
Corda, in place of preoccupied generic name Arethusina Barrande.

in the thorax, as it is not possible to tell where the pygidium begins. He compares the
species with E. ottawaensis. In front of the glabella the brim of E. dentoni is nar-
row, deeply concave, and the anterior rim is curved upward; while in EF. ottawaensis
the brim, at the front, is wide and nearly flat.

The author also describes and illustrates Bumastus billingis R. & N. Holasaphus
moorei Matthew. Pseudosphaerexochus apollo Billings, to which he refers the 4Am-
phion cayleyt Billings and Ceratocephala goniala Warder.

VI. Description of some new Asaphidae.

The author includes under the genus Hemigyraspis, a specimen figured in
Trans. Roy. Soc. Canada, vol. V, pl. 3, fig. 7, for a form similar to Asaphellus planus
Matthew, which the author now refers to Hemigyraspis meconnelli sp. nov. Includ-
ing under the genus this species, also Asaphellus planus Matthew and Hemigyraspis
collieana Raymond, 1910.

The author used as a type for his subgenus Hemigyraspis, dsaphus affinis McCoy,
as described by Salter, Mong. Brit. Tril., pl. 24, figs. 13-14, p. 164, and included
Ogygia desiderata Barr. Niobe menapieensis Hicks and N, solvensis Hicks with the
above species.

Under Basilicus Barrandi Hall, the author rernarks that this species has evaded the
eyes of the describers of Trilobites, and it was not until recently that the writer’s
curiosity to know what form it was which Voedes referred to Ogygia (Catalogue of
Trilobites, p. 324) caused him to unearth it.

Raymond places as syn. to Hall’s species Asaphus wisconsensis and romingeri Wal-
cott, 1879. Ptychopyge ulrichi Clarke, and Basilicus romingeri R. & N.

Under the Genus Ogygites Tromelin and Lebesconte, 1875.

The author describes and illustrates Ogygites canadensis Chapman, referring as syn.
Asaphus halli and hinksii, and comparing Asaphus latimarginatus Hall, with the
species.

The author describes as new Jsotelus latus, differing from I, gigas in having all its parts
much wider.

Raymond remarks, that the Museum contains a number of specimens of Isotelus
from St. Joseph Island, from which Stokes in 1823 figured a specimen as Asaphus
platycephalus, which compares well with DelKay’s /. gigas of 1824, and advocates the
dropping of DeKay’s species.

The following authors use platycephalus Stokes, in preference to DeKay’s name of
I, gigas: Bronn in 1835, Buckland in 1840, Burmeister in 1843, Roemer in 1851-56,
Nieszkowski in 1857, Billings in 1863, and Vogdes in 1893. I think due credit should
be given to Stokes and eliminate gigas.

The author also describes and illustrates Isotelus maximus Locke, and Brachyaspis
eltilis Raymond, the Asaphus platycephalus Billings. (Catalogue of Silurian Fossils of
Anticosti, p. 26, fig. 9b.)

VIII. A revision of the species which have been referred to the genus Bathyurus.

The author states that Billings erected the genus Bathyurus with Asaphus extans
Hall, for the type, and described many species under it. Some 50 species have been
referred to this genus; but in the revision the author only includes twelve, including
three new species.

Under the Family Bathyuridae Walcott, the author gives a revised generic descrip-
tion and describes the following species:

Bathyurus extans Hall, B. perplexus Billing, probably a synonym of B. extans, Bathy-
urus johnstoni sp. nov. closely allied to B. extans. Bathyurus sp. intermediate between
B. extans and B. superbus. Bathyurus superbus Raymond. This species attains a
larger size than any other known Bathyurus. B. longispinus Walcott, B. amplimar-

Billings, B. acutus sp. nov., B. arcuatus Bill., B. spiniger Hall, B. ingalli sp. nov. and
B. schucherti Clarke.

With Bathyurus mero Bill., for a type the author proposes the new genus Petigurus.

The genus is closely allied to Bathyurus, but differs as follows:

The facial suture reaches the posterior margin near the genal angle, the anterior
end of the glabella overhangs the concave border; glabellar furrows are entirely ab-
sent, and the eyes are somewhat farther forward. The pygidium is without concave
border, the ribs of the pleural lobes are reduced to nodes, and the axial lobe is ringed
for almost its entire length.

Petigurus Nero (Billings) an Irish species described by Reed, 1910, as Bathyurus aff.
nero, differs in the posterior end of the facial suture, turns sharply outward behind the
eye, forming a broad, fixed cheek, different from Petigurus nero, and from any species
of Bathyurus.

The author also refers to the genus Petigurus cybele (Billings).

Family Solenopleuridae Angelin:

The author gives the following diagnosis of his new genus Hystricurus: Type Bathy-
rus conicus Billings.

Glabella conical, tapering towards the front, outlined by deep furrows at sides and
front; glabella furrows absent; fixed cheeks long, extending nearly to the genal
angle; dorsal furrows paralleled by a narrow, convex ridge; eves of medium size, situ-
ated opposite the middle of the glabella; cranidium with deeply concave border in
front; pygidium rounded, with concave border, axial lobe prominent, with 5 rings,
and there are 5 pair of ribs on the pleural lobe; surface smooth or pustulose.

In addition to. the type which the author illustrates, he includes under the genus
Hystricurus crotalifrons (Dwight, 1884) and H. cordai (Billings), B. seelyi Whitt.
Bull. Am. Mus., vol. 2, p. 62, pl. 13, figs. 8-14, as a synonym, and not B. seelyi, vol. 1,
1886, referred to Bolbocephalus.

Family Proetidae Barrande:

Genus Haploconus nov. This genus is proposed to include Vrilobites related to
Cyphaspis, but differing in not having isolated basal lobes on the glabella, and in
having a less prominent axial lobe on the pygidium. Type Bathyrurus smithi Billings.

The author describes H. smithi, and includes in the genus Cyphaspis ? galenensis
Clarke, and probably C. ? brevimarginata Walcott.

Family Dikelocephalidae, Miller, 1889:

Miller includes in the family Dicellocephalus, Pterocephala and Ptychaspis.

The author proposes the new genus Platycolpus, for Bathyurus capax Billings, a
Trilobite with hemispheric, rather smooth cephalon, a depressed glabella extending
to the anterior border, which is a flat, striated rim; glabella furrows faint or absent;
eyes small, situated midway on the length of the head; facial sutures cutting the pos-
terior margin just inside the genal angles, and the anterior margin in front of the eye.

Pygidium semi-circular, without depressed border and with faint traces of segmen-
tation.

The author describes Platycolpus capax (Billings), P. eatoni Whitf., which has faint
glabella furrows, also P. dubius with a more pointed glabella, and P. barabuensis Whitf.
with a more convex glabella.

Family Agraulidae Dalman:

Under the new genus Plethopeltis with 4 graulos saratogensis Walcott, for the type
the author gives the following diagnosis:

Cephalon strongly convex, wider than long, without concave border or marginal
rim; glabella faintly defined, without glabella furrows; eyes small, situated well for-

ward; free cheeks, rather wide, smooth, with short spines at the genal angles; pygi-
dium small, with few traces of segmentation; convex; no border.

The author also includes Plethopeltis armatus (Billings) described under Bathyurus
by Billings in 1860.

Family uncertain.

Goniurus nov. TPype Bathyurus perspicator Billings, 1865.

Type diagnosis for this genus includes Trilobites, in which the facial suture, as in
Bathyurus, except that the fixed cheek extends a little farther towards the genal
angle; eyes very long, narrow and close to the glabella; glabella long, reaching al-
most to the frontal margin, tapering rapidly in front of the eyes; neck furrow sharp,
extending across fixed and free cheeks; genal angles with short, sharp spines; a nar-
row, elevated rim extends around the whole cephalon, and the cephalon is slightly
nasute in front; pygidium convex, triangular, with a long terminal spine.

Goniurus perspicator (Billings), G. caudatus (Billings), G. elongatus n. sp.

Matthew, Trans. Roy. Soc. Canada, vol., 1895, p. 269, referred to Bathyurus candatus
Billings, as a possible species of this genus Holasaphus; but the pygidium has no furrow
within the border.

Genus Lloydia Vogdes, 1890.

This genus was proposed by Vogdes in Ball. U. S. Geol. Sur., No. 63, p. 97, for
Bathyurus bituberculatus Billings, in honor of the first author on Trilobites.

Edward Lloyd published in Philosophical Trans., vol. 20, No. 243, p. 279, 1698, the
first description of ‘Trilobites.

Dr. Billings, in the Canadian Naturalist and Geologist, vol. 5, 1860, p. 317, provision-
ally refers to his genus Bathyurus, two species of fossils from Point Levi as Bathyurus
dubius and B. bituberculatus figs. 21 and 22. The second species, which is repre-
sented by a rough woodcut, presents a glabella, somewhat tumid and extending to
the front margin, with basal lobes elongated, oval and pointed at both ends, separated
from the glabella by shallow, obscure grooves; eyes opposite the mid-length of the
glabella.

Raymond places the first species of Bathyurus in the family Dikelocephalidae, under
a new genus Platycolpus bubius, and gives the following diagnosis of Lloydia Vogdes.

Whole animal oblong in outline; cephalon and pygidium regularly rounded, with ele-
vated convex borders; cephalon convex; glabella usually tapering towards the front and
reaching to the marginal border; glabella outlined by shallow or deep dorsal furrows;
eyes small, near the dorsal furrows, and situated halfway to the front; facial sutures
cut the posterior margin at the genal angles and the anterior margin in front of the
eyes; genal angles usually without spines; thorax of 9 segments, pleura deeply grooved,
ending in long, acute spines; pygidium with narrow axial lobe, which may have from
1 to 8 joints; pleural lobes smooth. The convex border which encircles the pygidium
is set off by a shallow furrow.

Type Bathyurus bituberculatus Billings, which is common in the conglomerates at
Point Levis near St. Joseph’s Church, Beekmantown age.

The author also includes under Lloydia, Bathyurus Saffordi, which differs from the
type, in lacking the basal lobes on the glabella; also Bathyurus solitarius, from Hare
Bay, Newfoundland. Lloydia oblongus (Billings), similar to L. saffordi, but has
straight sides to the glabella instead of tapering forward.

The author includes with doubt Lloydia strenuus Billings.

The illustration given by Billings, Pal. Fossils of Canada, p. 204, fig. 188, compares
well with the type of Bathyurus.

Dr. Raymond places two species described by Billings as Bathyurus quadratus and
breviceps, under a new genus Leiostegium, with the following diagnosis: General

form elongate, oval; cephalon and pygidium, nearly equal, both rounded, smooth and
convex; glabella quadrate, outlined by deep, narrow dorsal furrows and extending to
the very narrow elevated anterior rim; fixed cheeks wide, eyes small and far from
the glabella; thorax of 9 segments; pygidium almost semi-circular, unsegmented; axial
lobe elevated, extending nearly the whole length. No concave border. Type Bathyurus
quadratus Billings.

Notes on the ontogeny of /sotclus gigas DeKay.

Bull. Mus. Comp. Zoology Harvard College, vol. 58, No. 5, 1914, p. 247-263, with
3 plates.

The author gives the ontogeny of three Asaphids, namely, /sotelus gigas, I. maxi-
mus and Basilicus barrandei. Raymond remarks on:

I. Basilicus stage. The glabella is convex, narrowed behind, with a median tu-
bercle and basal lobes. The brim is wide and horizontal; the cephalon semi-circular
in outline; the genal angles produced into long spines; the axial lobe of the thorax
is narrow; the pygidium has a prominent axial lobe, and the pleural lobes of the
pygidium are ribbed.

II. Ogygites stage. The glabella soon becomes flattened and the facial sutures in-
termarginal, as in the adult of Ogygites.

III. Isotelus stage. "The head and tail both become smooth and the axial lobe
widens, as in the adult of Isotelus.

IV. Isotelus gigas stage. The head and tail becomes triangular and the spines
are lost from the genal angles, a combination of characters distinguishing this species.

The author remarks in regard to Isotelus Iowensis Owen, that it is so closely allied
to I. gigas, that where the two species occur together, as at Trenton Falls, it seems al-
most like hair-splitting to recognize two species. The adult Jsofelus iowensis, has long
genal spines extending to the 5th, 6th and 7th segments of the thorax.

Tsotelus maximus Locke.

The author remarks that the common asaphids at Cincinnati are Isotelus gigas, I.
maximus, I, latus, an undescribed species and one of the genus Onchometopus.

The four more common species of Isotelus in the Middle and Upper Ordovician are
classed as follows:

A. Shield about three-fourths as long as wide.

a. Adult without genal spines, shield subtriangular, J. gigas.
b. Adult with genal spines, shield rounded, J. ioqwemnsis.
B. Shields less than three-fourths as long as wide, regularly rounded.
a. Adult without genal spines, [. latus.
b. Adult with genal spines, J. maximus.

The author places Proetus spurlocki Meek as a young Isotelus, probably that of

I. maximus.

The article closes with a description of Basilicus Barrandet Hall, the author refer-
ring Asaphus romingeri Wale. and A. wisconsensis Wale. to the species, including
Ptychopyge ulrichit Clarke, under the same.

which makes it almost unique, in the wide, depressed brim at the anterior end of the
cranidium.

pygidium without ribs and a jointed axis, from the Clinton of New York.

This genus should include the French and Spanish Silurian form described as
Calymmene Aragoi by Rouault, which differs from, C. Saltert described by the same

BIBLIOGRAPHY OF PALASOZOIC CRUSTACEA 81

RAYMOND (Percy E)—Continued

The author remarks on the order Hypoparia in Beecher’s classification. Since the
young of practically all primitive Trilobites lack eves on the dorsal side, Beecher
grouped all Trilobites in which absence of eyes was a primary characteristic in his
First Order, Hypoparia. Recent studies and discoveries have led a number of in-
vestigators to the conclusion that blindness in the Agnostidae, Eodiscidae, Trinu-
cleidae, Raphiophoridae and Harpedidae is secondary and a degenerative not primitive
characteristic. If their position is well taken, then the order should disappear and the
families be distributed in the two orders which remain.

The author gives a figure of Agzostus nudus exhibiting the facial suture and free
cheeks. The facial sutures are not marginal, but intra-marginal. They meet in an
obtuse angle at the front and run backward just inside the margin, somewhat like the
course of the pre-ocular portion of the suture in an Homalonotus. ‘The sutures keep
within the angles, so that the fixed cheeks bear the genal angles—a Proparian char-
acteristic. The sutures in this manner cut off a yoke-shaped area, bounded outside by
the facial sutures and inside by a marginal edge, which follows the outline of the
base of the elevated portion of the cranidium (the glabella). Both limbs of the yoke
taper backward to a point, and it forms a continuous plate, with no vertical or
epistomal sutures. This plate has the position and aspect of a large epistomal plate,
but, whether called an epistoma or free cheek, the sutures which separate it from the
cranidium must be interpreted as the facial sutures.

The author includes only one family under Hypoparia, that of Eodiscidae, Eodiscus
as defined by Matthew, 1896, Mollisonia Walc. and Pagetia Walc. The discovery of
Pageria vootes and P. clytia, which bear eyes very close to the lateral margins, seems
to be a confirmation of the previous supposition that the Eodoscidae have ventral free
cheeks.

Dr. Raymond does not note Microdiscus caudatus Delgado, a species ae a mu-
cronated pygidium and with free cheeks, from the Cambrian of Portugal.

Delgado’s description, p. 349, pl. 3, fig. 12, Fauna Cambrian Haut Alemtejo.

Remarks: “La suture faciale, mais il semble que 4 partir de l’angle anterieur de
Yoeil; il décrit une courbe tres courbe, ayant la convexité tournée en dehors, allant
traverser le contour exterieur de la téte prés de la projection de l’oeil; postérieurement
il décrit aussi une courbe analogue, atteignant le contour intérieur en dedans de la
projection postérieure du centre de figure de l’oeil.”

I would suggest the new genus Delgadoia for this species as a type.

Dr. Raymond remarks on Shumardidae, that these little trilobites are too much of a
puzzle to be discussed at any length.

The paper ends in a discussion of Harpedidae and Trinucleidae.

The author would not include Orometopus in the last family, and remarks: “It is
so unlike any of the Trinucleidae, that the burden of proof that it belongs to that
family should be upon those who placed it there.”

Under Raphiophoridae, a figure of Lonchodomas portlocki Barr., which shows on
the ventral side of the head, a yoke-like plate similar to that of A gnostus nudus, but
instead of being confined to the ventral side it laps over the margins up onto the dorsal
side, being separated from the cranidium by a suture which has the course of the or-
dinary facial suture. The absence of eyes makes the analogy with the ventral plate
of Agnostus the more complete.

Having reviewed all the families of the Hypoparia the author remarks that there
seems to be a tendency in two directions—in Agnostus and Eodiscidae towards the Pro-
paria, and in the Trinucleidae and Raphiophoridae towards the Opisthoparia.

Mesonacidae:

The author remarks there can be no doubt that Elliptocephala. asaphoides and other

RAYMOND (Percy E)—Continued

species of this family show distinct traces of facial sutures, particularly of the part
behind the eyes. He gives a figure of the head of a young species of Elliptocephala
asaphoides Emmons.

In regard to the placing of Calymmenidae, Dr. Raymond follows that of Beecher
and places it in the Order Proparia, because the post ocular portion of the facial
sutures cut the genal angles in Pharostoma and the genal spines are borne by the
fixed cheeks. The free cheeks are decidedly Proparian.

The authors state that the genus Ceraurus was proposed in 1832 by Green, for a
new ‘Trilobite which he describes as Ceraurus pleurexanthemus, and refer to Green’s
Monograph, 1832, p. 83.

The original description of this genus was first published in The Monthly Journal
of Geology, June, 1832, p. 560, fig. 10, republished in the monograph.

Although the authors do not quote Corda, they take Reed’s classification of Cheirurus
into two groups on the form of the pygidae. The first with cyrtometopian pygidium
like Ceraurus Green. The second like Cheirurus insignis type of pygidium with 3
pairs of subequal pleural spines and a short median spine.

The American species they class as follows:

Ceraturus bispinosus sp. nov. ,

Glabella or occipital segment strongly spinose with a pair of short, horn-like spines
on the crest of the frontal lobe.

Ceraurus numitor Billings. A single medium spine on the neck segment.

Cerauru® mismeri Foerste. Glabella expanding rapidly forward. Genal angles with
spines.

Ceraurus hudosont Raymond. Glabella expanding forward; eyes more than one-
half the length of the head; a small form glabella expansion f in 4.

Ceraurus pleurexanthemus Green. A medium-sized glabella expansion 1 in 7.

2. Ceraurus milleranus M. & G. Eyes one-half the length of the head from the
posterior margin.

3. Ceraurus dentatus n. sp. Eyes less than one-half the length of the head from the
posterior margin.

Ceraurus granulosus sp. nov. Glabella with parallel sides.

The authors note in the Trenton fossils of Ceraurus pleurexanthemus Green, from
the typical locality, that the pygidium varies on the posterior border with either
aspinose and rounded border or with 2, 4 or 5 short spines or denticles.

The Ceraurus dentatus sp. nov.

The authors refer to Hall’s C. pleurexanthemus, Pal. N. Y., vol. 1, p. 1847, pl. 65, figs.
1d, th, li, and pl. 66, figs. la-1g.

The Ceraurus granulosus sp. noy. is the C. pompilius Raymond, 7th Report, Geol.
Vermont.

The Ceraurus Milleranus M. & G. is the Calymmene bucklandi, Anthony, 1839. (1
would suggest the older name.)

The authors refer Ceraurus rarus Walcott to Excrinurus Ceraurus pustulosa Hall to
Eoharpes.

To conform with the authors’ reclassification, the authors remark that besides the
species noted, that Vogdes’ Catalogue, made in the year 1893, contains a number of
other species, which do not belong to the genus as now restricted, as follows:

Cheirurus apollo Billings, to the genus Anacheirurus. Cheirurus glaucus, C. satyrus
and C. perforator Billings, belong to Nieszkowskia (Schmidt subgenus of 1881).

They refer Ceraurus niagarensis Hall, Ch. tarquinius Bill. Ch. nuperus Bill. and C.
hydei Weller, to Cheirurus, though the last two show a curious parallel development
in that they have a Ceraurus-like pygidium. (Then why divide the genus?)

Woodwardian Museum Notes. On the evolution of the genus
Cheirurus.

Geol. Mag. London, Decade iv, vol. 3, 1896, pp. 117-123 and pp. 161-167.

The author arranges the genus Cheirurus as follows:

1. Cheirurus (Anacheirurus) type, C. Frederic: Salt. Cambrian.

The Tremadoc species has 11-12 thoracic segments, each of which is deeply
grooved along its middle. Pygidium has 4 rings and 3 short pleural lobes on each side,
which are grooved throughout and extend over the margin into spines.

2. Cheirurus (Eccoptocheile) type, C. claviger Beyrich. Ordovician.

Glabella oval, often much inflated. Thorax 10 segments, grooved imperfectly.

3. Cheirurus (Cyrtometopus) type, clavifrons Dalm. Ordovician-Silurian,

4. Cheirurus (Hemisphaerocoryphe) type, pseudo-hemicranium, Nieszk. Ordovi-
cian,

The basal lobes of the glabella are separated by a strong glabella, side furrow
joining the neck furrow. ‘These lobes are less elevated than the rest of the glabella.

5. Cheirurus (Sphaerocoryphe) type, 8. cranium Kutorga. Ordovician,

6. Cheirurus (Nieszkowskia) type, cephaloceros, Nieszk. Cambrian and Ordovician.

7. Cheirurus (Pseudosphaerexochus) type femicranium Kutorga. Ordovician.

The characteristics of the above two genera are 12 thoracic segments and the pres-
ence of a longitudinal row of puncta instead of a furrow on the inner portion of each
pleura.

8. Cheirurus (Group 1 with cyrtometopian pygidium) type, C. Exsul Beyr. Or-
dovician-Silurian.

In this group the anterior pleura of the tail are enlarged and project behind the
posterior ones.

Barton refers this group to Ceraurus.

9. Cheirurus Group 2 type C. bimcronatus Murch. Ordovician-Silurian.

In this group the pygidium has 3 pair of pleura with free ends. ‘The fourth pair are
represented by a single medium terminal piece.

Barton refers this group to Cheirurus.

10. Cheirurus (Crotalocephalus type, C. articulata Munster. Devonian.

This genus is almost entirely restricted to the Devonian. The important subgeneric
characteristics are the continuous first and second side furrows of the glabella, the
triangular basal lobes, which nearly or quite meet in the centre of the glabella at their
apices, and the nearly straight obliquely directed third side furrows.

count of their primitive adult cephalic features, combined with morphological char-

acters.

The genera Salteria, Avalonia, Bathynotus, Telephus and Cyphoniscus may be ulti-

mately found to possess eyes.

Notes on the genus Lichas.

Quart. Jour. Geol. Soc. London, vol. 58, 1902, p. 50.

The author classifies the Lichadidae into two groups as follows:

Group 1—Protolichas:

Sec. A. Corydocephalus type L. plamatus Bary.
—B. Dicranopeltis tvpe L. scaber Beyr.
—C. Platylichas type L. margaritifer Nieszk.
—D. Metopolichas type L. verucosus Eichw.
—E. Metalichas type L. cicatricosus Schm.
—F. Uralichas type L. Ribeiroi Delg.

—G. Ceratarges type L. armatus Goldf.
—H. Oncholichas type L. ornatus.

Group 2—Deuterolichas:

Sec. A. Hopolichas type L. tricuspidatus Beyt.
—B. Homolichas type L. angustus Beyr.
—C. Conolichas type L. aequiloba Steinh.
—D. Echinolichas type L. Eriopis Hall.
—E. Leiolichas type L. t/laenoides Nieszk.
—F. Paralichas type L. dalecarlicus Ang.
—G. Terataspis type L. grandis Hall.

—H. Ceratolichas type L. gryps Hall.

The classification is based on (1st) a group with a pair of bi-composite lateral
lobes to the glabella, and a more or less definite fourth pair of lateral lobes; (2nd) a
group with a pair of tri-composite lateral lobes, originating by the fusion of the
fourth pair, with the bi-composite pair of the preceding group.

There are considerable affinities between this species and A. acadicus Hartt, also
with 4. montis Matthew.

Microdiscus: The author uses M. punctatus Salter for the type of the genus and not
M. quadricostatus Emmons, certainly the young of the Trinucleus from the Hudson
River group; and remarks, “Should Pemphigaspis bullata Hall, prove to belong to this
genus, this name will have to be adopted as Emmons founded his genus Miecrodiscus
on a young of another genus.”

Matthew Trans. N. Y. Acad. Sci., 1896, p. 236, remarks, as a general rule, in the
genus Microdiscus the number of rings in the axis of the pygidium increase according
to the geological age of the species. ‘The majority of those of the Olenellus zone have
but few rings (4 to 6), but in the Paradoxides zone species with many rings (8 to 10,
even 12) are multiplied.

He divides the genus into four Sections: With long glabella—Section 1, Lobatus;

2

Section 3, Dawsonia; Section 4, Eodiscus.

Section 2, Speciosus. With short glabella

The following Timalayan species are described and illustrated:

Microdiscus Griesbachi sp. nov. The species agrees in general characters with /.
connexus Walcott, M. haimantensis sp. noy. Redlichia Noetlingi Redlich.

The author remarks that this species is very closely related to R. nobilis Walcott.
Indeed, it seems difficult to separate the new Chinese species R. chinensis Walcott, R.
finalis Walcott and R. nobilis Walcott, by any strongly marked and constant features
from the Indian species.

Zacanthoides indicus sp. nov. Oryctocephalus Salteri sp. nov., O. cf. Reynoldi Reed.

Under the genus Ptychoparia, Corda, 1847, the author remarks:

There has been extraordinary diversity in the use of the generic name Ptychoparia,
and in spite of the recent efforts of paleontologists to bring order out of chaos it can-
not be said that uniformity of usage prevails at the present date.

= BIPLIOGRAPHY OF PALAXOZOIC CRUSTACEA 9 |

REED (F. R. Cowper)—Continued

He also remarks with regard to Ptychoparia that there happily cannot be any dis-
pute as to the type of the genus, for Corda’s first described species, Ptychoparia striata
Emmrich, is well known and universally acknowledged.

Reed quotes Corda’s original description of the genus and remarks that Pompeckj
agrees with this strict limitation of the generic name Ptychoparia, but instead of re-
garding it as a subgenus of Conocephalites, as Wallerius did, prefers to place the latter
as a subgeneric division of the genus, which is followed by the author with C. Em-
merichi Barrande, as a type.

With regard to the genus Liostracus Angelin, the author quotes Matthew’s divisions
of the genus Ptychoparia and Liostracus, and remarks that the only constant differ-
entiating feature of value is the shape of the genal angle, spined or rounded.

Matthew takes L. aculeatus as a type, but Brogger is followed by Wallerius in re-
garding the genal angles as typically spined, as in L. costatus Angelin. Reed places
the genus as a subgenus to Ptychoparia.

Also Conocephalites, with C. Emmrichi Barrande, as a type. ‘Vhe leading charac-
teristics of it are: 1—the long narrow eyes; 2—the position ot the eyes near the
glabella; 3—the course of the facial sutures, which behind the eyes run out almost
horizontally before bending back; 4—the furrow on the eye lobes; 5—the absence of
occular ridges; 6—the flat border.

The author describes Ptychoparia spitiensis sp. nov., P. Stracheyi sp. nov., P. urceo-
lata sp. nov., P. consocialis sp. noy., P. admissa sp. nov., P. pervulgata sp. nov., P.
maopoensis sp. nov. P. defossa sp. nov. Ptychoparia (Liostracus)civica sp. nov.

Bathyuriscus Stoliczkai sp. nov.

Dicellocephalus interpres sp. nov. The author compares it with D. Dewiner Billings
and other species, remarking that D. Dewinei and D. Hisingeri of Billings cannot
rightly be retained in the genus Dicellocephalus.

Genus Agraulos Corda, 4. aff. Roberti Matthew, 4. simulans sp. nov., 4. ? fervidus.

Anomocare Angelin, 1854, 4. conjunctiva sp. nov.

The peculiar course of the marginal furrow, so as to make a broad V in front of the
glabella, occurs also in several species attributed to Ptychoparia, P. sp. ind. Walcott,
from Yellowstone, and P. teucer Billings. Vhe author compares 4. Angelini Grénwall.
Anomocare sp.

Schantungia Lorenz, 1906, 8. ef. freguens Dames.

Reed remarks, that unfortunately the name Schantungia is apparently precccupied,
Walcott having employed it for a type of trilobites from China in 1905, but without a
figure. If it is proved that the type of Walcott’s Shantungia and Lorenz’s Schantungia
belong to different genera a new name must be given to this group or genus contain-
ing Dames’ C. frequens.,

well-rounded convex cranidium and obscure glabella.

Amphilichas conifrons nov.

This species differs from A. Trentonensis Hall, in the entirely different outline of
the middle lobe of the glabella, which in the former is widest behind and in the new
species broadens forward.

Ceratiocaris (Liminocaris) salina nov.

Spathiocaris Emersoni Clarke.

These specimens differ markedly from the strange valves figured with S. Emersoni
on plate 34, fig. 13, Pal. N. Y., vol. 7, which latter possesses a) much broadened flat
posterior fold and a very shallow anterior notch. The author makes a new species
of this form, referring it to Pholadocaris Luthert.

Spathiocaris lata nov., S. chargrinensis nov., S. Cushingi nov., S. Williamsi nov.
This is of larger size than the congenors and is readily distinguished by its broad form
and coarse lines.

On p. 98 the author gives a discussion on the genera Spathiocaris and the Discino-
carina and certain organic bodies called Cardiocaris, Pholadocars, etc., by Woodward
and Clarke, considered as Crustaceans by other authors (Roemer, DeVerneuil, Kayser
and Dames) as aptychi of Goniatites.

Lepidocoleidae. Anatifopsis Wardelli nov.

Pseudoniscus.

The eyes of this genus have for some time been an object of speculation. Niesz-
kowski, pl. 2, fig. 15, who first described a Pseudoniscus, figured a small incision along
the edge of the fixed cheek as place for the eye; Eichwald Lethaea Ross, p. 1445,
speaks there of large lunular eyes, and Woodward, Mong. of the Merostoma, p. 177,
fig. 65, restored the cephalon completely with eyes.

Article V. The presence of a median eye in Trilobites.

Gives figures in text of Isotelus gigas and Basilicus tryannus. It is claimed in this
paper that most, if not all, Trilobites possessed a median or parietal eye on the glabella.
A great number of species, belonging to more than 30 genera, possess a distinct tu-
bercle on the glabella. This tubercle occurs alone in many genera otherwise smooth,
as in Asaphidae and is hence of functional importance. The author gives a list of the
species with median eye tubercles.

Article VI. The cephalic suture lines of Cryptolithus.

The author gives figures in the text of Dionide formosa Barr., D. atra Salter and

tubercle.

The author proposed a new genus Hughmilleria for a small form, which from its
general appearance in many ways suggests the genus Eurypterus, but a study of its
structure shows it to be closely related to Pterygotus.

The author described Hughmilleria socialis nov. and var. robusta noy. var. A new
species of Eurypterus is included under the name of EF. pittsfordensis, which closely re-
sembles E. lacustris, approximately of the same size, also in the position and shape of
the eyes. The posterior portion of the cephalon flares out in FE. pittsfordensis, or at
least broadens out in a hyperbolic curve, while E. lecustris is marked by the nearly
parallel sides of the cephalon.

The author describes as Cryphaeus attavus a species with a head and a short, tri-
angular pygidium, which shows a faint development of four pairs of marginal lap-
pets, seen best by the four pairs of pits within the doublure.

Dr. Clarke in hiy paper on Devonic of Parana, p. 156, remarks: This, certainly, is
not a Cryphaeus, even phylogenetically, for exceedingly young forms of Cryphaeus
have suthciently demonstrated that the ontogeny presents no four-spined stage. The
tail is similar in the character of its lappets to those obscure structures in Proboloides
pessulus, a new genus created by Clarke in the same work.

The subgeneric name of Ctenopterus was used on account of the long, flattened seg-
ments of the endognathite; the lack of serrations on the segments, such as is found in
Eurypterus; the presence of the long joint, belonging probably to the walking leg or
balancer characteristics of Stylonurus, and the long, broadened spines or bristles which
are especially characteristic of the subgenus Ctenopterus.

The first part of Baron ‘Toll’s important contribution to Cambrian literature refers
to the earlier work of Dr. F. Schmidt, in which he places some of these fossils as
Devonian, but Toll correctly refers them to the Cambrian. One of these is Doryphyge
Slatkowskii, described under the genus Proetus by Schmidt—the three others are re-
ferred to Anomocare Pawlowskii Schm., Liostracus Maydelli Schm., and Solenopleura
sibirica, described by Schmidt under the genus Cyphaspis.

On plate 1 are figured some new species of Trilobites from a new locality.

‘Two minute species are referred to the genus Ptychoparia, which Dr. Matthew, in
his review of Toll’s paper, remarks might be compared with the Strenuella type of
Agraulos.

The Agnostus described as 4. Schmidti has an unusual association, if occurring in
strata with Microdiscus. ‘The Agnostus, however, is flatter than the typical species of
the Paradoxides beds, and Dr. Matthew says it may be an earlier form.

ULRICH (E. O.) and BASSLER (Ray S.)—Continued

The valves are usually short, semi-elliptical in outline, and sharply lobed.

Group Beyrichia Buchiana:

The anterior and median lobes are joined, but the anterior lobe is thinner and the
ventral connection proportionally thicker than usual, the combination giving to the

united lobes a striking similarity to the horseshoe ridge in the B. ungula section of
Bollia.
Group Beyrichia tuberculata:

‘This section comprises a number of species, in which the anterior and posterior lobes
are broken up by minor furrows—the posterior lobe into 2, the anterior lobe into from
2 to 6 or 7 node-like parts. Beyrichia Buchiano-tuberculata Reuter, would represent
about the simplest type, and B. pustulosa Hall and B. Noetlingi Reuter the most complex.

Group Beyrichia Salteriana:

The species of this group are not as large as those of the preceding groups and
differ in the fullness of their lobes and proportionate narrowness of the furrows.

Group Beyrichia clavata:

The small group includes B. Jonesti Boll, and possibiy B. umbonata Reuter.

Subgenus Sfeusloffia, new.

Group Beyrichia Linnarssont:

This group includes B. antiqua, B. acuta, B. simplex, B. Linnarssoni, B. signata, B.
beyrichiodes and probably B. erratica Krause.

Group Beyrichia interrupta:

The illustrations given by the authors show possible derivation of the B. interrupta
group from Eurychilina, and its relations to Beyrichia clavata group and to Steusloffia.

The authors place under Kloedenia the following species:

Kloedenia apiculata Jones, K. Barretti (Beyrichia Barretti Wel.), K. centicornis n.
sp., K. concinna (Beyrichia concinna J. & H.), K. fimbriata n. sp., K. granulata
(Beyrichia granulata Hall), K. initialis (Beyrichta initialis Ulrich), K. intermedia (B.

ensianna plicata Jones).

Of the above species AK. initalis and K. praenuntia are Middle Ordovian and K.
simplex late Devonian. All the others Silurian.

The genus Kyammodes Jones is closely allied, distinguished chiefly by the much
greater inequality of its valves, the thick ventral edge of the right overlapping the
smaller left valve. There are some peculiar differences in lobation also.

Kloedenella new genus. Genotype Aloedenia Pennsylvanica Jones.

The genus includes some 8 to 10 species, two of them probably only varieties rang-
ing in time from the Clinton to Middle Devonian. The British species Beyrichia ?
bicaesa J. &. K., may be included.

This genus is divisable into two sections:

In the first, the genotype, the posterior and median furrows are shorter than in sec-

tion number 2, and the anterior furrow either wanting or more or less well-developed.

)

In the 2nd section, of which Beyrichia Halli Jones, is a good example, the posterior
and anterior furrows are long, subequal and extending nearly or quite across the valve.

Kirkbyina new genus. Genotvpe Beyrichiella ? reticosa Jones and Kirkby.

Kirkbyina resembles Primitia, but is readily distinguished by its overlapping valves
and thicker anterior end.

Beyrichiella J. & K. Genotype B. cristata J. & K.

The shell is relatively longer than that of Kirkbyina, and its larger valve is not
the right, as in that genus, but the left.

The author remarks on the family Acidaspidae Barr. (used for the xii family, with-
out a family name), that this term is used in preference to Odontopleuridae of Bur-
meister (used by this author for a family name), which latter name had more re-
cently been suggested by Etheridge and Mitchell in 1897, inasmuch as the genus
Acidaspis Murch. (January, 1839,) and Emmrich’s name Odontopleura (1839) is of
later date. There was no date of publication given on Emmrich’s De. Trib. Dis-
sertates.

The author refers to Murchison’s Acidaspis, on p. 55, as a similar genus.

The author quotes Barrande, Vogdes and Clarke on the family and gives figures
of Odontopleura ovata, Selenopeltis Buchi, Ceratocephala prevosti and C, Danai,

Proetus ? placidus nov.

This species from Chouteau limestone of Sedalia has the lateral lobes of the pygidium
smooth, similar to the Silurian species of France named by Rouault Calymmene Arago
and C. Salteri, although it belongs to a different group of the Proetidae, with only
nine thorax segments. The head is parabolic in form, genal angles rounded. ‘The
eyes are similar in location to those of Phillipsia Sampsoni from the same locality.
The tail has eight axial joints with indications of two faintly defined segments on the
lateral lobes.

Cryptonymus. Genotype (. variolaris Brong.

Although Eichwald used this term in 1825 for certain Asaphidae and Illaenidae, he
used the same term in 1840 for such species as Calymmene punctatus and C. variolaris,
which was adopted by Angelin. The tesm should stand under the strict rule of
priority for the second use of the term.

to E. expansus. C. obtusus Ang., E. raricostatus Wal., C. laevis Ang., Encrinurus
Bowningi Foerste, E. tuberculatus Collie.

Certain species described by Barrande under the genus Cromus have been referred
by Novak to the genus Encrinurus on account of the direction of the facial sutures,
which are the same in both genera. They are Cromus Beaumonti, C. Bohemicus, C.
transient and C. intercostatus. The Encrinurus Novaki Frech, has been referred to
Encrinurus Beaumonti var., Novaki by Gornani and Le Regny.

Remarks the name of Encrinurus punctatus has often been applied to a common
Scandinavian species, first illustrated by Wahlenberg in an advanced publication of his
paper in 1818. Petrificata telluris Svencanae, Brunnich’s fossil from Bohemia, from a
soft yellow limestone, may be the Cromus Beaumonti Barr. ‘The author remarks, in
his paper, on two very imperfect petrified impressions of this fossil, that it had across
the fossil body impressed spotted rings, which marks are sufficient to distinguish them
from other species. The size of it seems to vary greatly, as my collection contains one
small and one very large back part of this species; each has 18 joints. The only
Bohemian Encrinuride recorded are those described under Cromus by Barrande and
Novak.

Albertella n. genus, Genotype 4. Helena n. sp.

The genus should be compared with the genus Zacanthoides. The cephalons of the
two genera are generically the same. The thoracic segments are the same type, but the
third or fourth segment of the thorax of Albertella is extended into long pleural spines,
and the thorax has seven instead of nine segments as in Zacanthoides. The pygidium
has one pair of spines instead of many spines, as in Zacanthoides.

Albertella Bosawworthi n. sp.

Oryctocare new genus, genotype O. Geikiei n. sp.

The cranidium of the cephalon of this genus is much like that of Oryctocephalus,
but the thorax and pygidium are unlike. ‘The pleurae are of the Olenus type, while
the pygidium is broad and of the Bathyuriscus type.

other genera of the Mesonacide.

Smithsonian Misc. Collections, vol. 53, No. 6, 1910, pp. 231-422, Pls. 22.

The author under the family Mesonacidae places:

1. Nevadia n. gen. genotype N. Wetksi n. sp.

In the type of this genus the posterior 11 segments have only the axial lobe and a
spinose continuation on each side. The spinose extensions of the posterior segments
are proportionally much rounder and smaller than those of the anterior 17 segments.
The pygidium is small without pleural lobes and transverse furrows.

2. Mesonacis: ‘This form is essentially the same as Elliptocephala, but it has an
enlarged third segment in the adult, and a strong spine on the fifteenth segment.

The species referred to Mesonacis are M. vermontana Hall, M. Mickawitzi Schmidt,
and M. Torrelli Moberg.

Elliptocephala Emmons, genotype FE. asaphoides Emmons.

In the genus the posterior five segments are more highly developed than the primi-
tive segments of Nevadia, but not as much so as the segments anterior to them.

Callavia Matthew, genotype Olenellus (Holmia) broiggeri Walcott.

This genus was proposed by Matthew, Am. Geol., vol. 19, p. 397, 1897, for O.
bréggeri and O. callavii Lapw., on acccount of the glabella differing from that of
Olenellus (Holmia) Kyjerulf.

Callavia has a trace of the constricted pleurae of the posterior portion of the thorax in
the two last segments. The broad thorax of Callavia with the falcate extensions of
the pleurae are unlike the narrow thorax of Holmia, with its spinos pleural extensions.

The glabella of Callavia is narrower and more primitive, and its intergenal spine is
less primitive. The pleural furrow of Callavia is narrow and oblique, like that of
Paradoxides, while the pleural furrow of Holmia and Wanneria is broad and straight.

The segments of Callavia appear to be nearer to Elliptocephala, than to those of
Holmia.

The author describes and figures Olenopsis zoppii Meneghini, O. agnesensis n. sp.
O. americanus n. sp., O. roddyi n. sp.

Dr. Bornemann distinguishes Olenopsis from QOlenus, on account of its having a
small, rounded tail shield, with unsegmented axis; by the particularly semicircular
outline of the cephalon; the conic, nearly smooth, glabella, and 14 or 15 body segments.

Crustacea:

Ptychoparia minuta Bradley, P. matheri n. sp. Conocephalina whitehallensis n. sp.
Pagodia seelyi n. sp. Agraulos saratogensis Wale. ‘This species was described as
Bathyurus armatus Billings (Walcott, 32 Ann. Rep. N. Y. State Mus., p. 131) and as
Ptychoparia (A.) saratogensis Walcott (Bull. No. 30, U. S. Geol. Sur., p. 21). Lonch-
ocephalus calcifernus Walcott, previously described under the genus Conocephalites
and Ptychoparia.

The species is closely related to Lonchocephalus wisconsensis Owen. It differs in
having a relatively shorter frontal limb and longer palpebral lobes.

Ptychaspis speciosus Walcott.

Dicellocephalus Hartti Walcott. This was the Conocephalites hartti Wale. (32 Ann.
Rep. N. Y. State Mus., p. 130).

The species differs from Dicellocephalus minnesotensis in details, but it appears to
come within the limits of the genus.

Dicellocephalus tribulis n. sp. allied to D. misa Hall.

The author also describes and illustrates several tracks of crustaceans under Owen's
gen. Protichnites. ‘The author remarks that the particular trilobite that left tracks on
the beaches of Potsdam sandstone time were undoubtedly species of the genus Dicello-
cephalus.

122 SAN DIEGO SOCIETY OF NATURAL HISTORY

WA LCO AWAD (( Charles Dz) —Continu ed

The author does not consider Climactichnites as the trail of a trilobite.

He describes Protichnites septemnotatus Owen and P. Logananus Marsh.

The author remarks that many of the impressions made by Protichnites tracks were
trifid, and made by a crustacean having legs terminating in a joint that had three
strong, narrow terminal spines.

On plate 45, the aurhor illustrates Neolenus serratus from Burgess Pass, in which
figure 4 shows the trifid arrangement of the short, strong spines of the terminal joint
of the cephalic legs.

The author describes from Robson Peak District the following new species of
Crustacea :

Holmia macer n. sp. The species resembles Holmia Kyjerulfi, but differs in details
of the head and thorax.

Wanneria occidens n. sp. The species differs from Olenellus Gilberti in its small,
short, palpebral lobe and strong marginal rim; also in the presence of an occipital
spine.

Callavia eucharis n. sp. The species has 23 segments in the thorax.

Callavia perfecta n. sp. This species has 17 thoracic segments. It differs from C.
crosbyi in having a more tapering glabella, smaller palpebral lobes, and in the ab-
sence of a strong occipital spine.

Olenellus Truemani n. sp. ‘This species differs from O. Thompsoni in having
shorter palpebral lobes and eyes, and smaller and shorter plural lobes of the third
thoracic segment.

bella recall those of MW. speciosus Ford.

Genus Redlichia Cossmann, 1902, to replace Hoeferia Redlich, 1901.

The author places the Olenellus Forresti Foord, Geol. Mag., Dec. 3, vol. 7, 1890, p.
99, pl. 4, figs. 2, 2a-b, under this genus.

Redlichia chinensis Walcott, differs slightly from the type. R. noetlingi, Redlich,

Albertella pacifica Walcott. >

The author compares the pygidium of this species with 4. bosaworthi Wale. and
Paradoxides desideraius Barrande.

The genus Dorypyge Dames, 1883.

The author does not include Olenoides Walc., under the genus Dorypyge, remark-
ing that it differs in the glabella expanding toward the front, while that of Dorypyge

contracts in front of the pits in the dorsal furrow; also that the pleural lobes of the
pygidium of Olenoides have broad, shallow furrows, with sharp, narrow ridges sep-
arating them; while those of Dorypyge have narrow furrows, with broad, rounded
ridges between them. Type D. richthofenit Dames, 1883.

Dorypyge bispinosa Walc., D. richthofeni Dames, D. richthofeni laevis Wale.

Genus Teinistion Monk, 1903.

The genus is characterized by the peculiar glabella, narrow frontal margin and
spinose pygidium. Type 7. lansi Monke.

Teinistion alcon Walc., T. lansi Monke, T. sodent Monke, T. typicalis Walcott, de-
scribed under the genus Dorypygella by Walcott, 1905.

Stephanocare Monkei Walcott, 8. richthofeni Monke, syn., D. chione Walc., S. sinensis
Bergeron, S. sp. undt.

Genus Blackwelderia Walcott, 1906.

The genus differs from Teinistion in the character of the associated free cheeks and
pygidia, and the frontal limb of the cephalon; from Dorypyge in the form of the gla-
bella and free cheeks. The thoracic segments are alike in the two genera, and the
pygidia are of the same type.

Blackwelderia alastor Walc., described under Dorypygella in 1905, B. cilix Walc.,
described under Olenoides ? in 1905, B. sinensis Bergeron described under Calymmene ?
in 1899.

Genus Damesella Walcott, 1905. Type D. blackwelderi Wale.

The author remarks that in Damesella and Stephanocare the facial suture cuts the
posterior lateral margin outside of the genal angle, so as to leave the genal angle on
the fixed cheeks, and at the same time the spine, corresponding to the genal spine in
other genera of the order Proparia, on the free cheek, so Beecher’s classification should
be modified in relation to the exceptions made in these genera.

Ptychoparia axlis Walc., P. granosa Walc., P. impar Walc. and var., P. kochibei
Walc., P. ligea Walc., P. lilia Walc., P. tolus, P. typus Dames.

Subgenus Ptychoparia (Emmrichella) Walcott, 1911.

Genotype Ptychoparia theano Walc.

The subgenus differs from the following genera:

1. Ptychoparia in its smooth glabella and larger palpebral lobe.

2. Liostracus in having an arched or nearly flat frontal limb and rim and more
convex cranidium.

3. Conokephalina in its smoother glabella and wider fixed cheeks.

4. Anomocare in its smoother glabella and distinct palpebral ridge, and propor-
tionately shorter eye-lobes and glabella.

The author described under this subgenus the following species:

Ptychoparia (Emmerichella) bromus Walc., P. (E.) constricta Walc., P. (E.) eriopia
Walc., P. (E.) mantoensis, P. (E.) theano Walcott.

Genus Liostracus Angelin, 1854. Genotype L. aculeatus.

Two species which the author classes under the subgenus Emmrichella—mantoensis
and constricta—approach most nearly to the genus Liostracus.

Genus Conokephalina Brégger, 1886. Genotype C. ornatus Brogger, 1877.

124 SAN DIEGO SOCIETY OF NATURAL HISTORY

WALCOTT (Charles D.)—Continued

The genus occupies an intermediate position between Dikelocephalus and Ptychoparia,
characterized by its elongated palpebral lobes, narrow free cheeks and elongated gla-
bella, narrowing more or less slightly towards the broadly rounded front.

The Chinese species are: Conokephalina vesta Wale., C. belus Wale. C. dryope
Walc., C. maia Walc. and C, sp. undt.

Genus Crepicephalus, Owen, 1852. Genotype C. Lowensis Owen.

Crepicephalus damia Walc. This species, which is nearly related to C. lowensis,
differs by the form of the frontal limb and rim of the glabella and other details.

C. convexus Wale. and C. magnus Waic.

Genus Lonchocephalus Owen, 1852. Genotype L. famulus Owen.

The author refers the Ptychoparia tellus Walce., 1905, to this genus.

Genus Liostracina Monke, 1903. Genotype L. krausei Monke.

Genus Proampyx Frech, 1902. Genotype Anomocare acuminatum Ang.

Walcott remarks that Dr. Frech appears to have overlooked the fact that the spine
of the genus Ampyx is a spinose extension of the front of the glabella, while the nasute
projection of the frontal rim of Anomocare acuminatum is from an entirely different
division of the head.

Proampyx burea Wale.

Genus Pterocephalus Roemer, 1852. Genotype P. sancti-sabae Roemer.

The author describes Pterocephalus asiaticus Walc., P. busiris Wale. and P. liches
all from fragments of the head and tails.

Genus Shantungia Walcott, 1905. Genotype S. spinifera Wale.

The genus is characterized by the large palpebral lobes, nearly smooth truncato-
conical glabella, and the long, spinose extension of the front, which is unlike that of
Ampyx, as the latter proceeds from the glabella; while the spine of Shantungia is
from the frontal rim, in the same manner as that of Proampyx acuminatum Ang., but
differs in the character of the glabella and palpebral lobes.

The only species described is that of the type.

Genus Inouyia Walcott, 1911.

The species referred to this genus have a swollen, tumid frontal limb; small pal-
pebral lobes; a convex subrectangular glabella; strong dorsal furrows about the gla-
bella, and marked glabellar furrows.

A graulos abrota Walc., A. dirce Walc., 1. dolon Walc., A. dryas Wale., A. nitida
Wale., 4. obscura Walc., A. sorge Walc., 4. uta Walc. and 4. vicina Wale.

Genus Pagodia Walcott, 1905. Genotype P. lotos Wale.

The author remarks that the genus differs from Dolichometopus and from the type
in the narrowing instead of widening of the glabella in front, in the presence of small
instead of large eye-lobes, short instead of long postero-lateral limbs and obscure gla-
bella furrows.

The species referred to this genus are Pagodia bia, P. dolon, P. lotos and P. macedo
Walcott.

Genus Lisania Walcott, 1911. Genotype Anomocarella ? bura Wale.

The species referred to the genus are all small, represented by cranidia and asso-
ciated free cheeks and pygidia.

pauperata Walc., S. sp. undt.

Genus Chuangia Walcott, 1911. Genotype Ptychoparia batia Wale.

The genus proposed for a group of Upper Cambrian Trilobites in which the cephalon
has a truncato-conical or subquadrangular glabella; a narrow concave frontal limb
and smooth test.

Three species are described: Chuangia nitida, C. mais and C. framenta.

Genus Menocephalus Owen, 1852.

Doctor Owen proposed this genus for Trilobites having a highly convex hemispherical
glabella, with a narrow border and broadly rounded front cheeks, tumid surface pus-
tulate.

The genotype of Menocephalus was destroyed by fire many years ago.

Dr. Walcott does not include in the genus the species described by Billings under
the names of Menocephalus sedgavicki and M. glabosus, which he refers to Soleno-
pleura, and remarks that M. salteri Devine, is the tvpe of an undescribed genus.

The author describes Menocephalus abderus, the Solenopleura abderus Walc., 1905,
M. acanthus Wale. (Solenopleura acantha Wale. 1905), M. acerius Wale., M. acidalia
(Solenopleura acidalia Walc., 1905), M. acis Walc. and M. admeta Walc., M. agave
Walc., M. depressus Walc., M. sp. undt.

Genus Levisia Walcott. Genotype 4graulos agenor Wale.

In this genus the cranidium is strongly convex, glabella truncato-conical, tumid and
with only a trace of glabella furrows; occipital ring narrow, at the sides broadening
rapidly toward the center, convex and extending backward into an obtuse spine;
frontal limb narrow; fixed cheeks tumid, one-half as wide as the glabella and with
small palpebral lobes midway of their length; postero-lateral limbs rather short and
marked by deep, narrow intermarginal posterior furrow, that separates a narrow,
rounded margin. The author describes Levisia adrastia Walc. (under the genus of
Menocephalus Walc., 1905), Levisia agenor Walc. under the genus Agraulos Walc.,
1905) and Levisia nasuta Walc., Levisia richardsoni Walc. The last two species are
from the Upper Cambrian at Point Levis, Canada.

The author includes under the family Dikelocephalina Beecher, 1897, the following
genera:

Dikelocephalus Owen, 1852.

Referring to the restricted genus the following species:

Dikelocephalus minnesotensis Owen, and a variation D, dalyi n. sp. The palpebral
lobe of D. dalyi is shorter than in typical Dikelocephalus, in this respect, resembling
some species of Anomocare, but not the typical species dnomocare laeve Angelin, D.

Dikelocephalus hartti Walcott. This is the Conocephalutes hartti Walc., 1879.

D. limbatus Hall, D. tribulis Walc., 1912, and D. vanhornei n. sp. The cranidium is
much like the genotype, but it has a shorter glabella and wider fixed cheeks.

2. Conokephalina Brogger, 1886, genotype C. ornatus Brogger.

BIBLIOGRAPHY OF PALASOZOIG CRUSTACEA 127

WALCOTT (Charles D.)—Continued

Walcott refers Dikelocephalus misa Hall to this genus. The other species referred by
Brogger to the genus, such as Dikelocephalus osceola Hall, are referred by Walcott to
a new genus Osceolia, and Dikelocephalus spiniger to the new genus Calvinella.

3. Saukia, new genus. The genus has a narrow frontal border about the cephalon,
and a glabella proportionately more elongated than in Dikelocephalus. ‘he pygidium
is less expanded and more elongate than that of Dikelocephalus. Genotype Dzikelo-
cephalus lodensis Whité.

The author describes Saukia coloradoensis n. sp., S. crassimarginata Whitfield, 1882,
S. fallax n. sp., junia n. sp., S. leptaenarum Wiman, 1907; S. leucosia n. sp., 8S. lodensis
Whitf. the type S. marica Walc., 1886; S. pepinensis Owen, 1852; S. pyrene n. sp., S.
rustica n. sp., S. stosei n. sp. S. wardi n. sp.

4. Osceolia, new genus. This genus is characterized by its concave frontal limb,
palpebral lobes, narrow fixed cheeks and transverse pygidium with its anterior segment
extended beyond the margin as a long spine. Genotype Dikelocephalus oseola Hall,
1863.

5. Calvinella, new genus. Genotype Dikelocephaius spiniger Hall, 1863. This genus
is like Saukia, but differs in form of the glabella, presence of strong occipital spine, and
proportionally more elongated pygidium. It differs from Osceola in frontal limb of
cephalon, presence of occipital spine and character of pygidium.

The author refers to the genus Dikelocephalus newtonensis Weller, 1903; Calvinella
ozarkensis n. sp. Dikelocephalus spiniger Hall, 1863, and Calvinella tenuisculpta n. sp.

The author gives a historical review with a summary of the genera and species.

A new genus, T’sinania, with J//laenurus canen for the genotype, is given on page 43.
The genus differs from Illaenurus Hall, in having the cranidium rounded in front, by
the incurving of the facial sutures, and short postero-lateral limbs. He refers several
species to the new genus previously included under Hall’s genus, viz: Tsimania canens,
T. ceras, T. cleora and T. dictys.

——— Cambrian Geology and Paleontology, No. 3. Cambrian Tri-
lobites.

Smithsonian Misc. Coll., vol. 64, No. 3, 1916.

The author, under the Order Proparia, describes several new genera.

Family Menomonidae—Menomonia a new genus with Conocephalites, calymenoides
Whitfield as the genotype.

Millardia, a new genus with M. semele as genotype. Refers one new species M.
avitas and Conocephalites optata Hall, also, to the genus.

Dresbachia, a new genus with D. anata as the genotype.

Norwoodide, a new family with a new genus, Norwoodia, with five new species:
Genotype N. gracilis, also N. ponderosa, N. Saffordi, N. simplex and N. tenera.

The cranidium, with its Ptychoparia-like glabella and small eyes and broad pleural
furrows, are primitive, while the few thoracic segments ($ or 9) and relatively large
tail, suggests the sub-family Phacopinae. Under the order Opisthoparia, he describes
Agraulos stator n. sp.; also Acrocephalites Wallerus, with a translation of that au-
thor’s description of the genus, with nine new species. Refers Solenopleura ? stenome-
topa Ang. and Conocephalites vulcanus Bill. to the genus.

Compares the new species 4. Haynesi and tutus with the genotype, dcrocephalites
insignis has narrower fixed cheek and frontal limb of 4. stenometopus, A. Americanus

128 SAN DIEGO SOCIETY OF NATURAL HISTORY

WALCOTT (Charles D.)—Continued

is a larger species than the genotype. .J. aster has a frontal boss much like the type.
Acrocephalites multisegmentus has 25 thoracic segments. A. aoris, a species much like
A. tutus; also A. glomeratus, a species like 4. ? maqus.

The author describes seven species under Lorenz’s genus Alokistocare, of which 4.
althea, A.?labrosun, A. pomona and A. ticida are new. He refers Ptychoparia 2
Linnarssoni and P. ? prospectense to the genus, and includes a figure and description
of the genotype Conocephilites subcornatus Hall and Whitfield, which he compares
with the new species A. althea.

The author includes under the genus Lonchocephalus eight species, five of which are
described as new: Lonchocephalus appalachia, L. bunus, L. pholus, L. plena, L. sos pita.

Describes and illustrates the genotype L. Chippewaensis Owen. Refers Shumard’s
Conocephalites minor and C. minutus Bradley to the genus.

_ Dr. Owen, plate 1-A, fig. 15, Geol. Sur. Wis., Iowa and Minnesota, 1852, p. 624,
refers to Lonchocephalus ?. a pygidium with lateral spines, similar to Dikelocephalus
Towensis, which Walcott places as the genotype of Crepicephalus.

The author remarks that Lonchocephalus is most nearly related to Liostracus An-
gelin, with only the cranidium for comparison. The difference between them is in the
frontal fimb and rim, and the absence of well-defined glabella furrows in Liostracus.

The author uses the Conocephalites calciferous for the genotype of a new genus
Saratogia, placing under it six species, four new: S. arses, S. aruno, S. hera and S,
volux, with Crepicephalus Wisconsensis Owen; including as syn. Dikelocephalus lati-
Jrons, described by Hall, also by Shumard, under this genus.

In the family Ceratopygidae, genus Crepicephalus Walcott (not Owen), the author
includes some 20 species.

Walcott uses Dikelocephalus ? Iowensis Owen, for the genotype.

Owen’s genus, as the name implies, was for a slipper-shaped, tapering glabella, a
true Ptychoparia species, which Corda named in 1847. Dr. Owen used the term
Dikelocephalus for the mattock-shaped heads, and refers to Dikelocephalus such species
as Walcott genotype, although Owen referred to Lonchocephalus, a form like Crepi-
cephalus Iowensis Walcott, on p. 624, pl. 1-A, fig. 15.

Lonchocephalus might replace in part Anomocare, and Crepicephalus be referred to
Lonchocephalus for Owen’s Lonchocephalus, p. 624, pl. 1-A, fig. 15.

Walcott divides the pygidae into two groups:

1. The Crepicephalus Towenis group.

In which the postero-lateral margins of the pygidium extend backward on each side
from a broad base into a sharp, narrow spine. ‘Test nearly smooth. Upper Cambrian.

2. Crepicephalus Texanus group.

In which the postero-lateral spines are long, slender, and attached to the side of the
pleural lobe above the margin. Test granulated. Lower Cambrian.

The author describes and figures Crepicephalus angusta, C. camiro, C. comus, C.

cossensis, C. coria, C. dis, C. Towensis (Owen) A. Liliana, C. Texanus (Shumard) var.
danace and elongatus, C. thoosa, C. tripunctatus (Whitfield) also var. magnispinus, C.
tumidus, C. unca, C. unzia, C. upis, and two doubtful species.

Under the Family Oryctocephalidae, the author includes the new genus Vanuxemella.
This genus, represented by I’. contracta and V’. nortia, from the Lower Cambrian, has
a simple form, with some features suggesting Albertella. It differs in} absence of
glabellar furrows, shorter eye lobes, absence of prolonged third segment of thorax,
with only four thoracic segments. The long spines of the tail spring from about the
fifth segment, while in Albertella they appear to be the extension of the first or second
anterior segment.

Trilobites.

Smithsonian Misc. Collections, vol. 64, No. 4, pp. 303-456, plates 45-67, 1916.

The author describes and illustrates the following Cambrian Trilobites:

Corynexochus bornholmiensis Gronwall, C. brennus Wale. C. bubaris Walc., C.
capito Walc., C. clavatus Walc., C. delagei Miquel., C. minor, C. senectus (Billings),
C. spinulosus Ang., C. stephenensis (Walc.).

Refers Corynexochus romingeri Matt. to C. stepiensis, Corynexochus 2. umbonatus
Angelin to the genus ®glina.

The new subgenus Bonnia is proposed as a subgenus to Corynexochus, with Bathy-
urus parvulus as the genotype.

The author includes Corynexochus (Bonnia) busa nov., C. (Bonnia) fieldensis, the
Protypus fieldensis Walcot, 1908.

Corynexochus (Bonnia) parvulus the Bathyurus parvulus Billings, 1861.

Bathyuriscus (Poliella) new subgenus.

Most of the species of Poliella are small, with from seven thoracic segments to

b

eleven segments and a small pygidium.

The genotype Bathyuriscus (Poliella) anteros Walcott.

The author includes eight species under the subgenus: Bathyuriscus (Poltella) anteros
nov., B. (P.) powersi, B. (P.)occidentalis nov., B. (P.) primus, B. (P.) caranus nov.,
B. (P.) sylla, B. (P.) balus nov., B. (P.) probus.

Dolichometopus.

Dr. Walcott refers eleven species to this genus: Dolichometopus acadicus Matt., D. ?
alceste Walc., D. baton Walc., D. 2 bessus Walc., D. bion Walc., D. boccar Walc., D. 2
deois Walc., D. ? derceto Walc., D. ? dirce Walc., D. 2 expansus (Walc.), D. productus

The other species of Dolichometopus, such as Dolichometopus ? convexus Billings,
referred to Bolbocephalus, D. ? gihberulus Bill., to Platycolpus, D. hyie Wale., to
Anomocare, D. occidentalis Matt. to Bathyuriscus, D.?rarus Bill. to Bolbocephalus,
D. tatei Woodw. to Redlichia.

The author forms a new subgenus, for certain species with a small palpebral lobe,
that lack genal spines on the free cheek, with Dolichometops (Housia) varro Walcott
as the genotype.

Family Asaphidae, sub-family Ogygiocarinac.

130 SAN DIEGO SOCIETY OF NATURAL HISTORY

WALCOTT (Charles D.)—Continued

Ogygopsis Klotzi (Rominger).

Orria new genus, with Orria elegans Walcott, as the genotype. Both Orria and
Ogygopsis suggest a stage of development between Bathyuriscus and Ogygiocaris. The
form is Ogygopsis-like, but differs in that the cephalon is smaller in proportion to the
thorax and the pygidium; fixed cheeks nearly absent between palpebral lobes and gla-
bella; palpebral lobes large and close to glabella; postero-lateral limbs long and nar-
row antro-lateral limbs; only a narrow space between the glabella and facial sutures;
pleural grooves of thorax segments broad and straight, instead of narrow and diagonal.

Asaphiscus the author refers to the genus.

Asaphiscus calenus Wale., A. camma Walc., A. ? capella Walc., A. ? granulatus
Walc., 4. Iddingsi Walc., 4. ? minor Walc., A. ? unispinus Walc., 4. Wheceleri Meek,
the genotype; also 4. agatho Walc., A 2? anaxis Walc., 4. calanus Walc., A. ? duris
Walc., with three sp. undt., and 4. ? florus nov.

Blainia new subgenus.

The species referred to Blainia have nine thoracic segments and from six to eleven
distinct anchylosed segments in the pygidium. Genotype Asaphiscus (Blainia) gre-
garius Wale.

Dr. Waicott includes four new species under the subgenus:

Asaphiscus (Blainia) elongatus, A. (B.) glabra, A. (B.) paula.

Blountia new genus.

The author refers seven species to this genus. Genotype Blountia minula Walc.,
Blountia ? alemon Walc., B. alethes Walc., B. alexas Walc., B. amage Walc., B.
andreas Walc., B. anser Walc., and B. mimula from the Upper Cambrian.

Maryvillia new genus. Genotype M. Arion and M, Ariston nov.

The pygidia associated with the cranidae of these species are elongate, with about
fourteen segments, which suggest transition from Blountia to Tsinania, as represented
by such species as Tsinania canens Walc.; etc.

Family Olenidae: Marjumia new genus. Genotype M. typa Walc.

This genus appears to unite characters found in several genera. The cephalon is
essentially that of Asaphicus, the thorax that of Ptychoparia, and the pygidium that of
Peltura scaraboides and Parabolina megalops.

In addition to the type the author describes Marjumia callas nov. Lisania Wale.
genotype Anomocarella bura Walc. and L. ? breviloba nov.

Illaenurus quadratus Hall.

Mesonacis Gilberti Meek.

Proparia, Family Eodiscidae: Pageti new genus. Genotype P. bootes Walc. The
new genus was proposed for the forms of Eodiscidae, in which the eye, the free cheeks
and facial sutures are developed. Two species described Pagetia bootes and P. clytia.

Cambrian Geology and Paleontology IV, No. 2. The Al-
bertella fauna in British Columbia and Montana.

Smithsonian Misc. Coll., vol. 67, No. 2, 1917, May 9, 1917.

The author describes from this formation the following Crustacae:

Agraulus stator Walc.

Ptychoparia candance nov.

The elongated body and small pygidium suggest 4 graulos stator, but the cranidium
is that of Ptychoparia, and there are 16 thorax segments, while 4. stator has 22, a
middle Cambrian form.

Ptychoparia ? charax nov.

This species is probably a subgenus with a Ptychoparia-like cranidia, with a broad
concave frontal border and rim, that will undoubtedly be placed in a subgenus.

dinaviea, with notes, Lund, 1910.

The author remarks that the first fasciculus of the work, which is printed in quarto
and written in Latin, (the copy I have bears no date. Plate 22 was not issued in
this edition), but published in Fasc. 2, was issued in 1851 with pp. 1-24, and plates
1-xxiv, under the title, ‘“‘Paleontologia Svecica.”

Lindstrém’s edition, 1878, states that this appeared in 1852.

The second fasciculus, containing plates xxv-xli and pp. 25-92 (or rather pp. 21-92,
because the latter part of the third sheet of fasc. 1 was reprinted in essentially altered
form), appeared in 1854, when the title of the work was also altered into ‘Paleon-
tologia Scandinavica,” for the evident reason that there are a great number of species
from Norway and Bornholm cited in this fasciculus. Pages I-lx were added, contain-
ing an account of Silurian stratigraphy, and one page of ‘Addenda et Corrigenda,”
besides which plates xx and xxii were enchanged for new ones.

In 1878 the entire work was re-edited by G. Lindstrém, under the title of “Pars 1
Iconographia Crustaceorum Formationis Transitionis.” In this work facs. 1 and 2 form
only the first part of the projected work.

In 1855 Angelin got a public subvention for editing fasc. 3. This was not published,
but several of the plates, intended for this fasc. were printed. Two of these plates,
A and B, reproductions exclusively of Crustacea, have probably been appended to pri-
vately distributed copies of Paleontologia Scandinavica. Some of these plates distributed
in some way are cited in literature, Grénwa]!! Danm. Geol. Unders. 11 Raekke, No. 13,
p. 107 (note at foot of page), quotes Table XLIII, on which Paradoxides Davidis
Salter is reproduced under the name Paradoxides Pingelli Beck MS.

Before Angelin set to work writing “Paleontologia Scandinavica,” he sold collections
of Swedish fossils, several of which he had himself named. A list of these collections,
embracing five decades, was printed under the title “N. P. Angelini Mus. Pal. suecicum,
Sectio prima, Petrefacta formationis s. d. transitionis superiors centuria, | ma.”

When Angelin in “Paleontologia Scandinavica” cites one of these new species he
puts “nob” after the name and not new species.

The notes on pp. 12-48, contain notes and corrections to Angelin’s work. Lorenz,
since the issue of this Index, has referred Solexopleura branchymetopus Ang. to the
genus to Ptychoparia. 7

These notes are supplementary to page 1, Occasional Paper iv, Cal. Acad. of Science,
1893.

In a note to the author from Dr. Sv. Leonh. Tornquist, who was a student under An-
gelin, he remarks, that ‘as to the plates XLIII-XLV of ‘Paleontologia Scandinavica,’
Angelin seems himself to have rejected them. Be this as it may, when after the au-
thor’s death the work was re-edited by the Academy of Science, it was decided that the
said plates, owing to their incorrectness, should be maculated, and all the copies were
accordingly destroyed, in order to prevent their being cited. Some proof sheet may,

served if they are not mentioned.”

a departure from the type from the Silurian stock.

Zygobeyrichia apicalis nov. and Z. extrema noy. This is distinguished from Z. apicalis
by its shorter and more gibbous form; and from species of Kloedenia it differs by the
complete loss of the posterior lobe, the greater depth and length of the sulcus and the
ventral prolongation, ete.

Dr. Henry Woodward, one of the best authorities on recent and fossil Crustacea,
retains Rominger’s genus Ogygopsis, and remarks that Ogygopsis Klotzi differs from
Ogygia proper in having a well-defined ocular ridge and a narrow palpebral lobe.
It seems convenient to separate this Rocky Mountain form generically from the other
examples of Ogygia.

The author illustrates Drepanura Premesnili Bergeron (which, like D. Ketteleri
Monke, is founded upon pygidia and separate and imperfect head shields, also with
elongated cheek-spines. The lateral caudal spines are very much more elongated in
D. Ketteleri and remind one of the very long lateral cheek and caudal spines of Bathy-
notus holopyga Hall).

served in Daphnia.

The position of the Merostomata.
Geol. Mag., Decade v, No. 7, July, 1913, p. 293, two text figures.
The author gives a sketch of the genus from McCoy’s weird restoration of Ptery-
gotus problematicus, in fifth edition of Lyell’s Manual of Elementary Geology, 1855,
p. 420.

Pterygotus Anglicus. Dithyrocaris Scouleri

Also the further discoveries of Pterygotus, made by Robert Slimon in the Geol.
Sur. Memoir in 1859, illustrated by 16 plates and text figures.

Salter contributed a restoration of Pterygotus anglicus to Murchison’s Siluria, 1859,
edition. He gives only two pairs of appendages to the head. The operculum is
placed in front of the mouth, and the lower lip or metastoma is absent.

Dr. Nieszkowski, in his paper on Eurypterus remipes, gives restorations of the up-
per and under sides of Eurypterus, showing the appendages of the mouth in situ and
the thoracic plates on the under side of the body.

Other restoration of several forms of Pterygotus Stylonurus Eurypterus, without de-
scriptions, are given in David Page’s Advanced Text Book of Geology, 1859, all more
or less correct.

Excellent descriptions and figures of American species of Eurypterus and Pterygotus
are given by James Hall in Paleont. New York, vol. 3, pt. 1, pp. 382-419, 80 plates
and 10 additional plates, the accuracy of which still remains unchallenged.

Mr. J. W. Salter, in the Quart. Jour. Geol. Soc., 1862 and 1863, contributed descrip-
tions of Eurypterus and allied form of Pterygotus.

Dr. Henry Woodward figured and described a very complete example of Slimonia
acuminata in the Intellectual Observer, 1863, vol. 4, p. 229; also of Eurypterus lanceo-
latus in the Geol. Mag., 1864, vol. 1, p. 107, pl. 5, figs. 7-9. In 1865 he figured and
described Stylonurus scoticus, S. Poweriei, S. Symondsi Hemiaspis limuloides in the

Quart. Jour. Geol. Soc., vol. 21, pp. 482-92, plates 13-14. The same author, in 1866,
commenced a Monograph of the British Crustacea of the Order Merostomata, pub-
lished in the Paleont. Soc., 1866-1878, in which 14+ genera and 83 species are re-
corded, described and illustrated.

The author does not include in this historical sketch the paper by DeKay, 1825, who
gave the generic name of Eurypterus, or reference to Mitchell’s paper in the Am.
Monthly Mag., vol. 3, 1888, p. 291, in which he describes the now well-known Euryp-
terus remipes DelKay, as a fossil fish.

Woodward quotes the well-known paper by Dr. Holm, St. Petersburg Academy,
1896, and his investigations of Eurypterus fischeri from the Island of Oesel. In this
locality the fossils are not metamorphosed into carbonaceous film, as in other deposits,
and he was able to elaborate its organization in such detail that FE. fischeri has really
become the most completely known of all extinct animals.

Woodward’s paper includes two full-page figures of Eurypterus fischeri, from Holm’s
paper.

The paper closes with a notice of Dr. Clarke and Ruedemann’s memoir on the
Eurypterida of New York, noted in this Bibliography.

Rochdalhia Parker by Henry Woodward.
