This large genus possibly contains several natural groups, but our 

 analysis of the species has failed to define them. The physiognomy, 

 the dentition, and the size and position of the mouth vary, v/ith many 

 intermediate species," between two extremes. On the one hand are 



1 A pscudocaiulal developed. 



2 As Intermediate species may be mentioned : G. varnpinus Goode and Bean, C. spinulosus 

 (Gilbert and Burke), and C. paradoxus (Smith and Radcliffe).
