PRIONISTIUS new genus, COTTID. 
A genus resembling Triglops, from which it differs in numerous im- 
portant particulars, among which are the following: (1) its much 
slenderer form, (2) the absence of a series of bony tubercles along the 
bases of the dorsal fins, (3) the elongation of the exserted pectoral rays 
so that the lower portion of the fin is considerably longer than the 
upper, (4) the presence of serrations on all dorsal spines, and on the 
first soft ray, and (5) the emargination of the caudal fin.
