200 RESEARCH IN CHINA. 
Surface minutely punctuate under a strong lens; fine, radiating, irregular, 
elevated lines cross the frontal limb from the furrow in front of the glabella and the 
palpebral ridge at the flattened frontal rim, and also from the base of the eye-lobe 
to the margin of the free cheeks. 
This species varies from the described forms in the broad, relatively short gla- 
bella and the configuration of the frontal rim and limb. It differs from Anomocare 
(= Conocephalites) subquadratum (Dames) [1883, plate 1, fig. 9] in having a more con- 
vex glabella and frontal limb, and the front of the glabella is slightly less transverse. 
Formation and Locality—Middle Cambrian: (C5) Lower limestone member of 
the Kiu-lung group [Blackwelder, 1907a, pp. 37 and 39 (first list of fossils), and fig. 
8a (bed 30), p. 29], 3.2 miles (5.1 km.) southwest of Yen-chuang, Sin-t’ai district, 
Shan-tung; also (C52), in the lower part of the lower limestone member of the 
Kiu-lung group [idem (second list of fossils), and fig. 7 (bed 22), p. 27], near base of 
cliffs in mountain 1,000 feet (305 m.) high, 3 miles (4.8 km.) north-northeast of 
Sin-t’ai-hién, Shan-tung, China.

Cephalon of medium size, moderately convex, and longitudinally irregularly 
quadrilateral, exclusive of the free cheeks. Glabella moderately convex, rising 
gently from the dorsal furrow toward the center, so as to give it a slightly ridged 
appearance. A glabella 5 mm. in width has a length of 7 mm., exclusive of the 
occipital ring; surface apparently smooth; occipital furrow very slightly defined; 
occipital ring broad, very slightly convex, with a slight node a little in advance of 
the center; dorsal furrow shallow, but distinct on the sides and in front of the 
glabella. 
Fixed cheeks about one-half the width of the glabella, slightly convex; they 
merge laterally into the furrows outlining the palpebral lobes, and posteriorly slope 
rapidly to the posterior margin; palpebral ridges low, rounded, and passing outward 
and merging into the narrow palpebral lobe; they clearly mark the division between 
the central portion of the fixed cheeks and the rapid slope to the frontal rim; pal- 
pebral lobes about one-third the length of the cephalon; frontal limb narrow in front 
of the glabella, widening out at the sides and sloping downward with a gentle con- 
vexity; frontal rim nearly flat, separated from the frontal limb by a shallow furrow 
that curves slightly backward near the center so as to form an obtuse angle. In 
some examples there is a slight deepening of the furrow on each side of the incurved 
portion of the frontal limb; postero-lateral limbs short, and marked by a rather 
shallow, broad furrow parallel to their posterior margin. 
Thorax with ten transverse segments. Axial lobe nearly as wide as the pleural 
lobe exclusive of the falcate terminations of the segments, moderately convex and 
tapering gradually from the first to the tenth segment. Pleural lobes nearly flat 
for about one-half their width, and then curved gently downward; pleural furrows 
broad at the dorsal furrow next to the axial lobe and narrowing gradually along the 
outer half of their length and terminating in a long point as they curve out on the 
falcate ends of the pleural lobe of each segment. The ends of the pleurc of each 
segment curve backward on the line of the doublure as shown in figure 4a.
