Foi'wiation and locality. — Middle Cambrian, thin-bedded, greenish 

 g-ray liniestoiip iiiter)>edded in ochreous and g-reen, argillaceous shales; 

 4 miles east of Fung-lan-chon, 8han-si, China. 



Collected by Eliot Blackwelder. 



ANOMOCARE, species undetermined. 



This form is represented by a fragment of the central portion of a 

 large head much like that of Anomocare alclnoe Walcott." The frontal 

 limb and broad rim are similar to those of Anomocare teniemis Wal- 

 cott.'' It is the youngest representative of this type of Anomocare as 

 it occurs near the summit of the Cambrian system in China. 



Formation and locality. — Upper Cambrian, limestone interbedded 

 in green shales; 4 miles southeast of Yaii-fo, near Wu-t'ai-hien, 

 Shan-si, China. 



Collected b}' Eliot Blackwelder. 



Genus ANOMOC ARELLA Walcott. 

 Anomocarelld Walcoit, 1905, Proc. U. S. Nat. Mas., XXIX, p. 54. 

 ANOMOCARELLA CONTIGUA, new species. 



This species is represented b\' an imperfect specimen of the central 

 portions of the head, and numerous associated p}"gidia and free cheeks. 

 The head differs from that of Anomocarella chineni<is Walcott' in 

 having a more conical glabella, with the sides converging toward the 

 front, instead of being subparallel. The associated pygidium has a 

 shorter axis than that associated with ^1. chinensin, and a broader, 

 smoother border, 



A. contiyua occurs at the same localitv as A. chinensi.'<, but at a 

 slightly higher horizon. 



Formation and locality. — Middle Cambrian, lower central portion of 

 Ch'ang-hia formation, in deivso, gray limestone, inter])edded in green, 

 nodular shale; \> miles south of Yen-chuang, Sin-fai District, Shan- 

 tung, China. 



Collected by Eliot Blackwelder. 



ANOMOCARELLA IRMA, new species. 



This species is represented by two specimens of the central portions 

 of the head. These indicate that the head was .semicircular in outline, 

 and moderately convex. Glabella prominent, convex, sides straight 

 and converging gently toward the front which is broadly rounded; the 

 only traces of glal)ellar furrows are two faint scars near the front, 

 which extend fron^ the outer margin nearly to the median line of the 

 head; occipital furrow w ell defined, separating a rounded, rather strong 

 occipital ring; dorsal furrow distinctly defined at the sides and less 

 clearlv marked in front of the glabella.
