DESCRIPTION OF GENERA AND SPECIES. 197 
terior margin; palpebral ridge low, narrow, and merging into the strong palpebral 
lobe, which is about one-third the length of the cephalon; frontal limb narrow in 
front of the glabella, widening at the sides in front of the palpebral ridges; it slopes 
gently down to a rounded, shallow furrow, that separates it from a slightly convex 
frontal rim which is broader than the frontal limb in front of the glabella; postero- 
lateral limb narrow, about as long as the width of the fixed cheek and marked by a 
rather strong border and shallow furrow parallel to the border. 
Surface marked by scattered puncte, and very fine puncte visible only with 
the aid of a strong lens. 
This species is characterized by the shallow, rounded dorsal furrow, elevated 
palpebral lobe, and the smooth, slightly convex frontal rim. 
Formation and Locality.—Upper Cambrian: (C36) Upper part of the Ch’au- 
mi-tién limestone [Blackwelder, 19074, p. 36 (part of third list of fossils), and fig. 9 
(bed 2), p. 35], at Ch’au-mi-tién, Ch’ang-hia district, Shan-tung, China.

Anomocare bergioni WALCOTT, 1905, Proc. U. S. Nat. Mus., vol. xxrx, p. 47. (Described as a new 
species essentially as below.) 
Cephalon, exclusive of the free cheeks, longitudinally subquadrilateral, 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 out- 
ward 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 
the sides and less so at the front. 
Fixed cheeks very narrow, forming little more than a convex ridge between 
the dorsal furrow and the furrow within the palpebral lobe; they slope rapidly to 
the front, merging into the frontal limb, and posteriorly downward to a very 
short postero-lateral limb; palpebral lobes narrow, about one-third the length of the 
cephalon; palpebral ridge low and merging into the rim of the palpebral lobe; 
frontal limb short and sloping downward to a slightly convex frontal rim that is 
about twice as wide as the frontal limb in front of the glabella; the line of demar- 
cation between the frontal limb and rim is little more than a change in direction of 
the slope, the slope of the rim being less. 
The outer crust is exfoliated over most of the cephalon. Where preserved the 
outer surface is smooth under a strong lens. 
The length of the cephalon of the type specimen is 12 mm.; the glabella, exclu- 
sive of the occipital groove, 6 mm.; frontal limb, 1 mm.; frontal rim, 2 mm. 
This species was doubtfully referred to the genus Anomocare, as the glabella 
did not have the parallel sides so characteristic of that genus and the palpebral lobes 
were rather short. The reference to Anomocarella is based on the character of the 
frontal rim, the narrow fixed cheeks, and the general configuration of the glabella. 
Formation and Locality.—Upper Cambrian: (C33a) Talus near the base of the 
cliff of Ch’au-mi-tién limestone [Blackwelder, 1907a, p. 41 (part of last list of fos- 
sils)], 9 miles (14.4 km.) north of Sin-t’ai-hién, Shan-tung, China.
