194 RESEARCH IN CHINA. 
The subrectangular glabella is somewhat like that of Ptychoparia aclis [plate 12, 
fig. 8], but the short frontal limb and flat rim distinguish it from the latter species. 
It is associated with Conokephalina vesta [plate 13, fig. 9], from which it differs 
in the form of the glabella and palpebral lobes. 
A form closely related to this occurs about 100 feet (30 m.) lower at the same 
locality and section. 
Formation and Locality—Middle Cambrian: (C69) Limestone in shales about 
65 feet (19.5 m.) above the base of the Ki-chéu limestone, and (C72) thin green- 
gray limestone interbedded with ocherous and green clay shales, overlying the mas- 
sive oolite in the Ki-chéu formation [Willis and Blackwelder, 1907, pp. 139 and 145 
(first and third lists of fossils)], 4 miles (6.4 km.) east of Fang-lan-chén, Shan-si,China. 
Collected by Eliot Blackwelder. 
Anomocare subquadratum (Dames). 
Plate 18, Figure 11. 
Concephalites subquadratus DAMES, 1883, China, Richthofen, vol. Iv, p. 12, plate 1, figs. 9, 11. (De- 
cribes and illustrates a cranidium and associated pygidia.) 
Of this species we have several specimens of the cranidium and possibly the 
free cheeks and pygidium, but as the cranidium is associated with that of the closely 
related Anomocarella butes [plate 19, figs. 7, 7a~d] it is not possible to determine to 
which of the species they belong. The generic reference is of doubtful value. 
Formation and Localityx—Middle Cambrian: (35n) 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, Man- 
churia, China. 
Also from Locality (C7), Lower limestone member of the Kiu-lung group [Black- 
welder, 1907a, pp. 37 and 39], 2.2 miles (3.5 km.) southwest of Yen-chuang, Sin-t’ai 
district, Shan-tung. 
Collected by J. P. Iddings and Li San. 
Anomocare sp. undt. Walcott. 
Anomocare sp. undt. WALCOTT, 1906, Proc. U.S. Nat. Mus., vol. xxx, p. 584. (Discussed as below.) 
This form is represented by a fragment of the central portion of a large cephalon 
much like that of Anomocare alcinoe [plate 18, fig. 6]. The frontal limb and broad 
rim are similar to those of Anomocarella temenus [plate 20, fig. 7]. It is the youngest 
representative of this type of Anomocare as it occurs near the summit of the Cam- 
brian system in China. 
Formation and Locality.—Middle Cambrian: (C77) Limestone interbedded in 
green shales not more than 300 feet (go m.) above the Man-t’o shales [Willis and 
Blackwelder, 1907, p. 144 (first list of fossils)], 4 miles (6.4 km.) southeast of Yau-t’o, 
near Wu-t’ai-hién, Shan-si, China. 
Collected by Eliot Blackwelder. 
Anomocare spp. (a), (6), (c), and (d). 
Plate 19, Figures 3-6. 
Four forms of pygidia occur in various associations that have not been referred 
to any described species. 
One (a) is represented by figure 4. It occurs at Locality C64, Upper Cambrian, 
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
