190 RESEARCH IN CHINA. 
Surface smooth under a strong lens. 
The associated pygidium has a strong central axis marked by five or six rings 
that are very distinct on the broad, planulate margins. 
This species is strongly characterized by its peculiar glabella, with the elongate, 
narrow lobes near its base; also by the broad, slightly convex frontal rim. 
Formation and Locality—Middle Cambrian: (C19) Uppermost layers of the 
Ch’ang-hia limestone [Blackwelder, 1907a, p. 33 (part of last list of fossils)], at 
Ch’ang-hia, and (C26) near the top of the black oolite group in the uppermost 
layers of the Ch’ang-hia limestone [idem], 2 miles (3.2 km.) north-northeast of 
Ch’ang-hia, Shan-tung, China. 
The first collected by Li San; the second by Eliot Blackwelder.

(Described and discussed as a new species essentially as below.) 
This species is represented by specimens of the cranidiuin and associated 
pygidia that are referred to it. It is closely related to Anomocare flava Walcott 
[plate 18, fig. 8]. It differs in details of frontal limb and border, glabella, and fixed 
cheeks. It has a less deeply impressed line between the frontal limb and border 
than that of A. flava. 
Formation and Locality.—Middle Cambrian: (35r) Fu-chéu series, limestones 
near the base of the series just above the white quartzite [see Blackwelder, 1907), 
p. 92, for general section giving stratigraphic relations], collected in a low bluff on 
the shore of Tschang-hsing-tau Island, east of Niang-niang-kung, Liau-tung, Man- 
churia, China. 
Collected by J. P. Iddings and Li San.

Anomocare flava WALCOTT, 1906, Proc. U.S. Nat. Mus., vol. xxx, p. 583. (Described as a new species 
essentially as below.) 
Cephalon, exclusive of the free cheeks, quadrilateral and moderately convex. 
Glabella slightly convex in front, becoming more convex toward the center, along 
which there is a very slightly indicated longitudinal ridge. A glabella 6 mm. in 
length has a width of 5.5 mm. at the base and 4 mm. opposite the anterior edges 
of the palpebral ridges, where the rounded front begins; the posterior pair of gla- 
bellar furrows is indicated on one specimen by a slight depression, on another two 
pairs of furrows are indicated by slight scars about halfway between the center and 
the sides of the glabella; occipital furrow shallow, scarcely more than indicating the 
line of division between the glabella and the occipital ring; the latter rises gently 
toward the center; dorsal furrow clearly indicated at the junction of the glabella 
and fixed cheeks, and also in front of the glabella. 
Fixed cheeks about one-third the width of the glabella, nearly flat back of the 
palpebral ridges, and sloping gently downward to merge into the frontal limb, and 
backward to the posterior margin of the cephalon; palpebral ridges low and rather 
broad; they terminate at the antero-lateral angles of the glabella from whence they 
extend obliquely backward to merge into the palpebral lobes; palpebral lobes little 
more than one-fourth the length of the cephalon, and rather prominent; frontal 
limb in front of the glabella about the same width as the frontal rim; it is slightly 
convex to the base of the rather abrupt posterior margin of the frontal rim.
