NO. 1415. CAMBRIAN FAUNAS OF CHINA— WALCOTT. 47 



Formation and locality. — Central portion of Chancy Hsia formation, 

 near the top of the oolitic limestone; 1 mile west of Chang- Hsia, 

 Shangtung-, China.

 Washington Expedition to China. 



Genus ANOMOCARE Angelin. 

 ANOMOCARE ALCINOE, new species. 



This species is represented by a single specimen, preserving the 

 anterior portions of the central part of the head, exclusive of the free 

 cheeks. These parts indicate that the head was large, moderately 

 convex, and longitudinally quadrilateral, exclusive of the free cheeks. 



Glabella slightly convex, rising gently from the dorsal furrow 

 toward the center; faint indications of three pairs of glabellar fur- 

 rows are shown by reflected light over the smooth surface; sides sub- 

 parallel to the rather broadl}^ rounded front; occipital furrow and 

 ring unknown. 



Fixed cheeks about one-half the width of the glabella, nearly flat 

 opposite the palpebral lobes, and sloping gently to the frontal limb, 

 into which they merge in front of the palpebral lobe; the ocular ridge, 

 starting just back of the antero-lateral angle of the glabella, extends 

 obliquely out to the narrow palpebral lobe; frontal limb nearly flat; 

 it slopes gently from the glabella and palpebral lobes to a raised line 

 which separates it from the broad, slightly concave frontal rim. 



The surface appears to be smooth under a strong lens. " 



An associated pygidium has a broad planulate margin and convex 

 axis, with slight indications of about six segments. The most nearly 

 related form from China is A. decelus. In the latter form the frontal 

 rim is slightly convex, while in A. alcinoe it is slightly concave. 



Formation and locality. — Middle Cambrian, upper portion of the 

 Chang Hsia formation, in limestone nodules; 3 miles south of Kao 

 Chia Pu, Hsin Tai, Shangtung, China.

 Washington Expedition to China. 



ANOMOCARE BERGIONI, new species. 



Head, exclusive of the free cheeks, longitudinally sub-quadrilateral, 

 convex. Glabella truncato-conical, moderately convex, and marked 

 in the cast by two pairs of glabellar furrows; also a low, rounded, 

 median ridge; sides slightly arched outward opposite the palpebral 

 lobes; front broadly rounded; occipital furrow deep, rounded, and 

 arching forward slightly at the middle; occipital ring narrow and 

 rising at the center to form the base of a rather strong spine; dorsal 

 furrow strong at sides and less so at the front.
