Body moderate, the tail not conspicuously compressed. Length 

 of head 3 j'^j- to 3^, depth of body 3| to 4 in the total length ; 

 depth of head \\ to 1^, width of head 1^ to 2, of the slightly 

 convex interorbital region 3| to 4i,* diameter of eye 3|- to 4^ in 

 the length of the head ; snout mvich broader than long, very 

 obtusely rounded in front, not depressed, as long as to as much as 

 one-fourth of a diameter longer than the eye. Maxillary not 

 reaching to the vertical from the anterior margin of the eye, its 

 length 31 to 34 in that of the head. Ten gill-rakers on the lower 

 branch of the' anterior arch, all of them simple and tooth-like. 

 The space between the origin of the first dorsal fin and the 

 extremity of the snout is as long as or a little less than its distance 

 from the base of the last soft ray; the fourth spine is the longest, 

 1|^ to 14 in the length of the head and reaching when laid back 

 beyond the origin of the second dorsal fin in the ^, 14 to 2 in the 

 head and not reaching as far as the second dorsal in the <^; in the 

 (J the seventh soft ray is the longest, as long as the head, in 



* 4^ in one specimen.
