ANOMOCARELLA HERMIAS, new species 



Plate IS, fig. 10 



This species is represented by specimens of the cranidium that 

 have an unusually large and long palpebral lobe. This character is 

 sufficient to distinguish it from other described species. The sur- 

 face appears to be minutely punctate or marked by minute, shallow 

 pits. 



Formation and locality. — Middle Cambrian: (35n) Fu-ch6u series; 

 limestones near the base of the series just above the white quartzite, 

 collected in a low bluff on the shore of Tschang-hsing-tau island, 

 east of Niang-niang-kung, Liau-tung, Manchuria, China. 



Collected by J. P. Iddings and Li San. 



ANOMOCARELLA MACAR, new species 



Plate 15, figs. II, iia-b 



Of the Chinese species of Arwniocarella, the cranidium of this 

 species may be compared with that of A. tatian (Walcott) in that 

 the frontal limb curves more abruptly down toward the frontal 

 margin than in most species of the genus, and the frontal margin 

 also bends downward to a greater degree. The outline of the 

 glabella and fixed cheeks is almost similar in the two species. The 

 associated pygidia are more elongate than those referred to A. tatian 

 and have a greater number of segments in the axial and pleural 

 lobes. 



Formation and locality. — Middle Cambrian : (3511) Fu-chou series ; 

 limestones near the base of the series just above the white quartzite, 

 collected in a low bluff on the shore of Tschang-hsing-tau island, 

 east of Niang-niang-kimg, Liau-tung, Manchuria, China.

ANOMOCARELLA SMITHI, new species 



Plate 17, figs. 3. 3a 

 Dorsal shield of medium size, elongate-elliptical in outline, convex, 

 with the axial lobe strongly defined and convex. Cephalon semi- 

 circular in outline, with the genal angles extended into short, sharp 

 spines ; a narrow, flattened border extends across the front of the 

 cranidium and continues along the free cheeks until it passes into 

 the genal spines ; the posterior margin is narrow and distinctly 

 defined by a strong, rounded furrow that terminates in the dorsal 

 furrow beside the glabella. Cranidium with the front broadly 

 rounded, narrow fixed cheeks, small antero-lateral limbs, and narrow
