The author remarks that ‘‘it is evident from the new specimen of E/lip- tocephalus asaphoides from the shales of Washington county, N. Y., figured in Emmon’s American Geol., pl. 1, fig. 18, that this trilobite is a Paradoa- ides related to the group of P. spinosus, perhaps identical with the P. harlani of Braintree. Besides, the trilobite figured pl. 1, fig. 16, and called Atops trilineatus, is a true Sao, which genus is the most character- istic of the primordial fauna of Bohemia and Scandinavia.” Notice sur les gisements des lentilles trilobiti- féres taconique de la Pointe Lévis on Canada.

Sketches of Louisville and the Fall of the Ohio. Louisville, 1819. Somatrikelon megalomaton, p. 74, n. g. and n. sp. This new genus under the law of priority should replace the genus Phacops if it were not for the objection to Somatrikelon, which means the same as the word Trilobite used for the class. The name given to the species ‘‘ having very large eyes” corresponds to that given by Dr. Emmrich to the genus Phacops. The author refers ‘‘this very curious animal to the vermes class,” and remarks: ‘‘ At first view it appears to have three distinct bodies and one head, which is owing to the former being very broad (nearly one-half an inch) and divided throughout its length by two deep clefts, one on each side of the central part or back, which is elevated a fourth of an inch above the sides, is convex, and terminated at one end by a large head, furnished with unusually prominent eyes and a mouth formed like that of a snapping turtle. From the Falls of the Ohio.” The following diagnosis is given: ‘‘Corpus tripartitum, rugosum, sinuatum; extremitate altera acuminata curvataque dorso, arcuato, serie tuberculorum utro, bique, capite subro- tundo, oculis peramplis.” (Phacops rana Green.)

The genus Otarion was made up from the head of Cyphaspis burmeisteri Barr., connected with the pygidium of Cromus beaumonti Barr. The second species, described as Otarion? squarrosum, is referred by Barrande to Cheirurus quenstedti. Zenker uses two generic names for his new genus Conocephalus, the first on p. 48 in describing the genus and the second in his description of plate 5, where he calls it 7rigonocephalus. Both these generic terms had been used in natura] history for other genera, the first by Thurnburg in 1812 for a genus of the Orthoptera, and the second by Oppel in 1511 for the Reptiles. The typical species described as Conocephalus costatus on p. 49, and also in the explanation of pl. 5, figs.

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

Reynolds Inn, 7 miles north of Union Village, Washington County, N. Y. Taconie. Conformity to the rules governing nomenclature, which are intended to render justice to every investigator, the genus Atops Emmons, 1844, should replace that of Conocoryphe Corda described in 1847. The original figure of this species was the first primodial fossil described from American rocks; this species with Olenellus asaph- oides Emm. clearly defined the Taconic System in 1844 and its position below Murchison’s Lower Silurian of 1837. The fact that the original Cambrian was the same as the Lower Silurian cannot be recalled and in justice to Sedgwick it must be given to that system. —— TRILINEATUS Emmons, 1847; Nat. Hist.

The figures of this species given by Dr. Emmons are all imperfect. Ford’s figure given in Bull. U.S. Geol. Survey, No. 30, pl. 27, fig. la-b, shows a glabella anda pygidium, which is nearly semi- circular in form; the axis strong, composed of 7 segments, with a row of obtuse spines along the middle; lateral lobes composed of 5 segments, each with distinct intervening grooves; marginal rim nearly flat, widest towards the front and distinctly and regu- larly notched or denticulated all around. This may prove to be a species of the genus Olenoides. Conocoryphe TRILINEATUS Wal., 1887; Am. Jour. Sci., 3d series, vol. 34, p. 197, pl. 1, fig. 7 a-b. Conocoryphe TRILINEATA Wal., 1890; 10th Rep.

He refers the following figures to the genus: Plate 1, fig. 8, Crepi- cephalus?, pygidium from the Miniskah Trilobite grit. Plate 1, fig. 18, Crepicephalus? wisconensis (n.s.), part of cephalothorax and a portion of the cephalic shield of D. granulosus? Plate 1 a, fig. 10, glabella of Crepicephalus n. g., near Miniskah.

Survey Wisconsin, Iowa, and Minnesota, p. 576. Dr. Owen in his report, Geol. Survey, Wis., Iowa and Minnesota, described four new genera of trilobites under the names of Dikelocephalus, Lonchocephalus, Crepicephalus and Menocephalus. The second genus is now classed as a synonym to Anomocare with Anomocare chippewensis, and A. hamulus, de- scribed in the report. Thereis a third species mentioned by Owen on p. 624, and also plate 1 a, fig. 15, Pygidium of Lonchocephalus (?) with long, slender, divergent caudal spines; also a similar pygidium, figured plate la, fig. 13, as Dikelocephalus (2) iowensis. Walcott, Bull. U. S. Geol, Survey, N. 10, p. 36, places the latter species under a subgenus to Ptychoparia, using Dr. Owen’s Crepi- cephalus for it on account of the peculiar pygidium, overlooking, however, the fact that Owen has referred a similar pygidium directly to his genus Lonchocephalus on p. 624 of his report. Under the law of priority the genus Ptychoparia replaces Crepicephalus, and the later name should be cancelled in toto, and not be retained in a modified sense. Lonchocephalus forms an exception to this rule, if we divide the genus into two sections, retaining Anomo- care for hamulus and chippewensis, and Lonchocephalus for the species described by Dr. Owen with long, slender, divergent caudal spines which includes Dikelocephalus (?) iowensis. —— sp.?

Burmeister separates Dalman’s species Caly- mene concinna from the type of the genus Proectus, and gives it the new generic name of MWonia, with descriptions and figures of A. concinna, A. stokesii and A. verticalis. Phaeton Barr., 1846; Notice Prélim., p. 62. The author herein gives the new generic term Pheton for species of Proetus with fimbriated pygidia. PRINOPELTIS Cord., 1847; Prodr., p. 121.

This genus includes such species as Proetus elegantulus Loven, with twelve seg- ments in the thorax. Forsersta McCoy, 1847; Sil. Foss. Ireland, p. 46. This author uses for the types of his genus Forbesia latifrons and F. stokesii, which is the same as that used by Barrande in 1846 for his genus Photon and Angelin in 1875 for the genus Phetonides. Genal angles produced into long spines; pleure of the pygidium segmented; glabella furrows present and large tubercles terminating the neck furrow. Gerastos Goldf., 1843; Neues Jahrbuch fiir Mineral., p. 557. This genus is a Proetus with G. levigatus for its type, a species identical with Proetus cuvieri Stein. ; CATALOGUE OF TRILOBITES. 339 PROETUS. Trigonaspis and Cylindraspis Sand.; Verst.d.

This generic name suggested for a minute Trilobite includes a speci- men having an expanding glabella, with two anterior side nodules, similar to those of Battus pusillus Sars, the genus being allied to Agnostus, differing therefrom in having a regularly ribbed py- gidium, similar to that of an Asaphus. Comparing Shumardia granulosa with Conophrys salopiensis Call. (Quart. Jour. Geol. Soc. London, vol. 33, p. 667, pl. 12, fig. 7), which Brégger (Sil. Etagen 2 und 3, p. 125) refers to as a synonym to Battus pusillus, we find a similar characteristic in the glabella. The pygidium of Shu- mardia granulosa has however a more semi-oval form, with a greater number of axis rings and an additional number of ribs on the side lobes. 356 CALIFORNIA ACADEMY OF SCIENCES. SHUMARDIA. SOLENOPLEURA. The head of Shumardia granulosa differs from Battus pusillus in haying a groove, which runs from the anterior front of the gla- bella to the frontal margin of the head, a characteristic of some species of Agnostide (vid. Brégger, Sil. Etagen 2 und 3, pl. 1, fig. 10). Mr. Billings remarks that ‘‘in some specimens this furrow has at the bottom a small triangular tubercle, giving the glabella the appearance of having a projecting angular process in the middle of its front.” Iam more inclined to view this triangular tubercle as a point of attachment for the muscles of the jaws, and not as a process for the attuchment of antenne. Mr. E. Billings in the same book gives a description of a second species, which he calls Shumardia glacialis, figured p. 283, fig. 270. The species is represented with three glabella furrows, and should not be included in the genus Shumardia. If these forms are not embryonic, I would advocate the acceptance - of Shumardia amongst the Agnostide for such species as Shu- mardia granulosa Bill. and Battus pusillus Sars to replace the later generic term of Conophrys Call.

Murchison has revived this old name of Lhwyd’s, and all subsequent paleon- tologist have adopted it. 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 genus Cryptolithus. 360 CALIFORNIA ACADEMY OF SCIENCES.
