TOL. 41. 



Head 3^ in body length; depth 2|-; eye 4-4^ in head; depth of 

 preorbital 3^ to 4^; D. XI or XII, 13; A. Ill, 11; scales in longi- 

 tudinal series 56 to 64, in transverse between insertions of dorsal 

 and anal 7 or 8/13 or 14; gill-rakers 6 + 8. 



Dorsal profile arched more strongly from snout to dorsal than 

 posteriorly; mouth low, close to straight ventral profile; lower jaw 

 included; snout short, rounded, slightly overhanging premaxillaries, 

 its profile approaching the vertical at tip. Eyes well below upper 

 surface of head, interorbital region arched strongly from side to side, 

 3 in head; frontals prominent. Snout 2{ in head, maxillary 2-|,

small; inner largest; third consisting posteriorly of two very large 

 molars; fourth and innermost ending at middle of jaw. Three rows 

 of molars in lower jaw, outermost smallest, rounded, second enlarging 

 posteriorly, to form three very large molars, the last largest; third 

 row ending before middle of jaw. Three incisor teeth on either side 

 of both jaws in front, set somewhat rodent-like. 



Third and fourth dorsal spines longest, 2 J to 2| in head; last 2§ 

 in head, slightly longer than succeeding ray, which is longer than 

 the last rays. Anal spines similar to dorsal spines, the second and 

 third equal and of same length as the latter. Anal rays rapidly 

 decreasing in length to last, which is half that of first. Fin outline 

 straight. Pectoral long, reaching anal, equal to head plus two-thirds 

 of eye diameter. Ventrals 1| to IJ in head. Caudal nearly as long 

 as head.
