the occipital furrow; dorsal furrow clearly defined on the sides and slightly marked 
in front of the glabella. 
Fixed cheeks narrow, not over one-fourth the width of the glabella; palpebral 
lobes about one-third the length of the cephalon, somewhat nearer the posterior 
than the frontal margin of the cephalon; palpebral ridge short, and not prominent; 
it terminates a little back of the antero-lateral angle of the glabella; frontal limb 
narrow, very slightly convex, and sloping downward, with a well-defined furrow 
separating it from the strong, rounded, thickened frontal rim; four small, shallow 
pits occur in the furrow, one strong one on each side of the center, and one faint one 
opposite the outer edges of the glabella. 
Surface finely granulose under a strong lens. The largest cephalon has a 
length of 5 mm. 
This species is distinguished from other species of the Chinese Cambrian by its 
rounded, strong frontal rim, and very slightly tapering glabella, in the latter respect 
recalling such forms of Anomocare as A. alcinoe [plate 18, fig. 6], A. minus Dames 
[plate 19, fig. 1], and Anomocarella butes (Walcott) [plate 19, fig. 7] from the Cambrian 
of China. 
Formation and Locality—Middle Cambrian: (C71) Massive cliff-making lime- 
stone in the central portion of the Ki-chéu formation [Willis and Blackwelder, 1907, 
pp. 139 and 145 (second list of fossils)], 4 miles (6.4 km.) southwest of Tung-yii, 
Shan-si, China.

(Described and discussed as a new species essentially as below.) 
This species is represented by specimens of the cranidium having an unusually 
large and long palpebral lobe. This character is sufficient to distinguish it from 
other described species. ‘The surface appears to be minutely punctate or marked 
by minute, shallow pits. 
Formation and Locality —Middle Cambrian: (85n) Fu-chéu series, limestones 
near the base of the series just above the white quartzite [see Blackwelder, 1907), p. 
92, for general section showing stratigraphic relations], collected in a low bluff on the 
shore of Tschang-hsing-tau Island, east of Niang-niang-kung, Liau-tung, Manchuria, 
China,

species. ) 
This species is represented by two specimens of the central portions of the 
cephalon. These indicate that the cephalon was semicircular in outline, and mod- 
erately convex. Glabella prominent, convex, sides straight and converging gently 
toward the front, which is broadly rounded; the only traces of glabellar furrows are 
two faint scars near the front, which extend from the outer margin nearly to the 
median line of the cephalon; occipital furrow well defined, separating a rounded, 
rather strong occipital ring; dorsal furrow distinctly defined at the sides and less 
clearly marked in front of the glabella.
