WALCOTT (Charles D.)—Continued 
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 auxhor 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. 
Cambrian Geology and Palwontoloey—2, No. 11. New Lower 
Cambrian subfauna. 
Smithsonian Misc. Coll., vol. 57, No. 11, 1913. 
The author describes from Robson Peak District the following new species of 
Crustacea: 
Holmia macer n. sp. The species resembles Holmia Kjerulfi, 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. 
The Cambrian faunas of China, 
Carnegie Inst., vol. 3, Aug. 1, 1913, 375 pp. and 29 plates. 
The Trilobites are described and illustrated on pp. 99-228, pls. 1-24. Genus Agnostus 
Brongniart. 
A gnostus chinensis Dames, very much like Agnostus Pic Aoraghi, 1902, p. 5, pl. 1, f. 
28. A. douvillei Bergeron. The author places 4. koerferi Monke, 1903, as a syn., 
A. kushanensis Walcott, A. parvifrons latelimbatus Lorenz, A. sp. undt. 
Genus Microdiscus Emmons. 
Microdiscus orientalis Walcott. The author remarks that the head and the occipital 
spine are much like those of M. convexus Wale. The transverse furrow of the gla- 
bella recall those of AW. 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, 
1901. 
R. finalis Walcott, R. nobilis Walc., R. sp. undt. three species. 
Genus Albertella Walcott, 1908S. 
Albertella pacifica Walcott. 
The author compares the pygidium of this species with 4. bosavorthi Walc. and 
Paradoxides desideratus 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
