196 RESEARCH IN CHINA. 
a gentle and nearly uniform curvature from side to side; on one specimen three pairs 
of glabellar furrows are very faintly indicated; the sides of the glabella arch slightly 
inward between the base and the rounded front; occipital furrow shallow, rounded, 
slightly separating from the glabella a very slightly convex occipital ring; dorsal 
furrow narrow but distinctly marked. 
Fixed cheeks a little less than one-half the width of the glabella and nearly flat; 
they merge into the furrow within the palpebral lobe, and posteriorly slope gently 
downward to the posterior margin; palpebral ridges low, rounded, and merging 
into the flattened palpebral lobes; in front of the palpebral ridges the cheeks are 
interrupted by an obliquely transverse ridge that extends subparallel to the palpe- 
bral ridge to the front of the glabella, where it merges into the frontal limb; frontal 
limb very narrow, sloping rather abruptly downward from the dorsal furrow to a 
narrow furrow separating it from a broad, slightly downward-sloping, nearly flat 
frontal rim; postero-lateral limb short and marked by a shallow furrow parallel to 
the posterior margin. 
Surface minutely punctate under a strong lens. 
The largest cephalon of this species has a length of 18 mm., with a width at the 
palpebral lobes of 19 mm. 
This large species differs from other forms by the very narrow frontal limb and 
the flat, downward-sloping frontal rim. 
A pygidium associated with the cranidium of this species is provisionally 
referred to it [plate 20, fig. 1c]; also a somewhat similar pygidium [fig. 1b] from 
Locality C4, and a hypostoma [fig. 1a] from Locality C2. ‘The three localities 
(C1, C2, and C4) are in the same faunal zone. 
I find that Anomocarella contigua Walcott [1906, p. 584] was founded on frag- 
ments of A. albion. 
Formation and Locality—Middle Cambrian: (C1 and C2) Lower shale member 
of the Kiu-lung group [Blackwelder, 1907a, pp. 37 and 40 (part of the third list of 
fossils), and fig. 10 (beds 4 and 5), p. 38], 2 miles (3.2 km.) south of Yen-chuang, 
and (C4) limestone nodules at the base of the lower shale member of the Kiu-lung 
group [idem (second list of fossils), and fig. 10 (bed 4), p. 38], 3 miles (4.8 km.) 
southwest of Yen-chuang, Sin-t’ai district; also (C57), limestone nodules in the 
lower shale member of the Kiu-lung group [idem (first list of fossils)], 3 miles 
(4.8 km.) south of Kao-kia-p’u, and 4 miles (6.4 km.) north of Sin-t’ai-hién, Sin-t’ai 
district, Shan-tung, China.

Anomocarella baucis WALCOTT, 1905, Proc. U.S. Nat. Mus., vol. Xxrx, p. 55. (Described as a new 
species essentially as below.) 
This species is represented by a single specimen of about one-half of the ceph- 
alon, exclusive of the free cheeks. This specimen indicates a moderately convex 
cephalon, somewhat longitudinally quadrilateral in outline. Glabella moderately 
convex, with the sides converging slightly toward the front; surface apparently 
free from furrows; occipital furrow broad, shallow, slightly curving forward near 
the center; occipital ring low, strong, and slightly convex; dorsal furrow shallow, 
not clearly defined. 
Fixed cheeks a little more than one-half the width of the glabella, nearly flat 
out to the elevated palpebral lobe and sloping with moderate rapidity to the pos-
