ridges are beautifully marked by irregular radiating ridges that 

 branch quite irregularly and are united by irregular cross-ridges so 

 as to give an anastomosing effect. 



Dimensions. — The dimensions are shown by the figures on pi. 17, 

 figs. 2 and 2a. 



Observations. — The cranidium of this species is much like that of 

 Anonwcarc Icevc (pi. 17, fig. i). Each has a broad, more or less 

 concave frontal limb and margin marked by radiating ridges, large 

 eyes, and an elongate glabella marked by five short lobes on each 

 side. 



The pygidium in each species is of the same type and the surface 

 has the same punctate character in each. 



Anonwcarc coiivexa is associated with several other species of 

 Aiiomocare. 



Formation a)id locality. — Middle Cambrian: (pox) Conasauga 

 formation ; in and attached to the outer surface of siliceous nodules 

 in argillaceous shales, Coosa V^alley, east of Center, Cherokee County, 

 Alabama. 



Collected by A. M. Gibson, 1884; and Cooper Curtice, 1885. 



ANOMOCARE EPHORI, new species 

 Plate 15, figs. 8, 8a 



This species is represented by specimens of the cranidium and 

 associated pygidia that are referred to it. It is closely related to 

 Anomocare iiava Walcott. 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. iiava. 



Formation and locality. — Middle Cambrian: (35r) 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-kung, Liau-tung, Manchuria, China. 



Collected by J. P. Iddings and Li San. 



ANOMOCARE LISANI, new species 



Plate 15, figs. 9, 9a-b 



This fine species is represented by numerous specimens of frag- 

 ments of the cephalon, segments of the thorax, and entire pygidia. 

 They are all compressed in a fine, argillaceous shale and usually only 

 a faint impression remains. The cranidium is not unlike that of
