NO. 1415. CAMBRIAN FAUNAS OF CHINA— WALCOTT. 53 



This species is associated witli Anomocare-'inmi/s Dames, from which 

 it differs in the cliaracter of the frontal limb and margin, in which 

 respects it also differs from Anoniocaretemenux and Anonioeare tatian. 

 It ma}' also be compared with the form from the St. Croix sandstones 

 of Wisconsin, illustrated b}' James Hall as (Jonocephalltes diadematns,^^ 

 and with A. alcinoe, from which it differs in having- a convex frontal 

 rim instead of concave. 



Formation and locality. — Middle Cambrian. Reddish limestone 

 near base of Chang Hsia formation in oolitic limestone. Yen Chuang, 

 Hsin Tai, Shangtung, China.

 Washington Expedition to China. 



ANOMOCARE TATIAN, new species. 



This species is most closely related to Anonioeare tenienus. It differs 

 from it in having a proportionately more convex and broader glabella 

 and stronger dorsal furrows. The associated pygidium is also longer 

 in proportion to its width, and it has eight or nine segments in its axis. 



The largest head has a length of 13 mm. exclusive of the frontal 

 rim, which is somewhat broken. This proba))ly had a width of about 

 2 mm. A glabella 10 mm. in length has a width of 8.5 mm. at the 

 base and 7 mm. at the broadly rounded front. 



Formation and Joc<dity. — Middle Cambrian. Near base of Chang 

 Hsia formation in gray oolitic series. Chang Hsia, Shangtung, China. 



Collected by Eliot Blackwelder, of the Carnegie Institution of 

 Washington Expedition to China. 



ANOMOCARE TEMENUS, new species. 



Head large, moderately convex, and transversely (juadrilateral, 

 exclusive of the free cheeks. Glabella slightly convex, rising gently 

 from the dorsal furrow to the center, which is marked b}^ a narrow, 

 longitudinal ridge. A glabella 14 mm. in length has a width of 10^ 

 mm. at the base and 8 mm. at the rounded frontal margin; indications 

 of three pairs of glabellar furrows are shown by reflected light over 

 the smooth surface; occipital furrow very shallow, scarcely more than 

 indicating the line of demarcation between the glabella and the rather 

 narrow occipital ring; dorsal furrows shallow. 



Fixed cheeks narrow and nearly flat; they merge laterally into the 

 large palpebral lobe and posteriorly slope down rapidly to the poste- 

 rior margin; ocular ridges low, rather broad, and clearly marking the 

 division between the central portion of the free cheeks and the rapid 

 slope to the frontal rim; frontal limb in front of the glabella narrower 

 than the frontal rim; it is slightly convex and merges into the narrow
