DESCRIPTION OF GENERA AND SPECIES. 217 
and moderately convex; it is marked in the cast of the interior by very slight traces 
of three pairs of short glabellar furrows and a very slight, narrow median ridge; 
dorsal furrow shallow but well marked; frontal limb nearly flat for a distance of 
2 mm. in front of the glabella, where it curves downward at an angle of about 45° 
for a distance of 3.5 mm. It is quite probable that at the angle between the flat 
portion and the sloping front there was some indication on the outer crust of a 
division between the two parts, if so, the shorter inner portion would be the frontal 
limb and the sloping outer portion the flat frontalrim. Exterior surface unknown. 
This species is very clearly characterized by the form of the frontal limb. The 
generic reference is very doubtful. 
Formation and Locality.—Upper Cambrian: (C64) Upper limestone member of 
the Kiu-lung group [Blackwelder, 1907a, pp. 37 and 42 (first list of fossils), and fig. 
10 (bed 20), p. 38], 2.7 miles (4.3 km.) southwest of Yen-chuang, Sin-t’ai district, 
Shan-tung, China.

Cephalon, exclusive of free cheeks, elongate quadrilateral in outline, moderately 
convex. ‘The convexity of the glabella is so slight that it is scarcely raised above 
the general surface of the cephalon; its outline is truncato-conical, with the front 
rounded; the interior cast appears to be without traces of furrows; occipital furrow 
transverse, narrow, rounded, and shallow; occipital ring of medium width, slightly 
convex; dorsal furrow lightly impressed on the sides of the glabella and scarcely 
perceptible in front of it. 
Fixed cheeks narrow, scarcely more than a line in front of the palpebral lobes; 
they widen out slightly in front and merge into the frontal limb, and posteriorly 
into the postero-lateral limb; postero-lateral limbs narrow, length unknown; frontal 
limb broad, slightly convex, sloping obliquely downward and passing into the smooth, 
nearly flat frontal rim almost without interruption from the very shallow transverse 
furrow; palpebral lobes small, about one-third the length of the glabella. 
The only surface markings are the fine, irregular lines that extend from in front 
of the glabella outward across the broad frontal limb to the frontal rim. 
The type and only specimen of the cephalon in the collection is 11.5 mm. long, 
with a width at the palpebral lobes of 8 mm.; the glabella is 6 mm. in length; the 
frontal limb 2 mm.; frontal rim, 1.5 mm., and occipital ring and furrows, 2 mm. 
This species has the narrow fixed cheeks, small palpebral lobes, nearly smooth 
glabella and broad, slightly convex, combined frontal limb and margin typical of 
the genus. It resembles Anomocarella chinensis [p. 200] in its narrow fixed cheeks 
and conical glabella, but it has small palpebral lobes and a convex instead of con- 
cave, combined frontal limb and margin. 
Formation and Locality.—Upper Cambrian: (C38) Crystalline limestone near 
the base of the Ch’au-mi-tién limestone [Blackwelder, 1907a, p. 36 (part of first list 
of fossils)], at Ch’au-mi-tién, Shan-tung, China.

This species is represented by a portion of the glabella and frontal limb, and a 
fragment of a large free cheek associated with it; also an associated pygidium which
