The genus CMtonotus differs from Icelinus and Tarandichthys in 

 having 3 instead of 2 ventral rays. 



TARANDICHTHYS FILAMENTOSUS (Gilbert). 



Pectorals 17, the lower 8 thickened, with moderately exserted tips, 

 the upper protruding a little beyond the outline of fin. Ventrals

TARANDICHTHYS TENUIS (Gilbert). 



In addition to other striking characters in this species, it is marked 

 by two sharp, strong spines behind the base of the supraocular fila- 

 ment. These are still more strongly developed in T. cavifrons, but 

 are wanting in T. filamentosus. In adults the lower 8 pectoral rays 

 are thickened, with moderately incised membranes, the upper of these 

 modified rays projecting abruptly beyond the margin of the fin.

ICELINUS QUADRISERIATUS (Lockington). 



There is a single filament near tip of maxillary, a broad one above 

 posterior part of orbit, and a few scattered ones along lateral line. 

 In males the anal, ventrals, and the lower pectoral rays are blackish, 

 as well as the branchiostegal membranes. 



The normal fin formula is dorsal IX, 14; anal, 12; pectoral, 16 

 (7+9). As in other species of Icelinus, the ventrals are I, 2, not 

 I, 3, as given in current descriptions.
