is one ray less in dorsal and anal. Head 4.25 in body; depth 7.5; D. 11; A. 8. 



Eye 4 in head, snout 2.5; interorbital 4; pectoral 5 in body. Scales 162-42. In

 bony interorbital space, 6.5 in head; postorbital length of head equal to half its 

 whole length; maxillary ending under center of eye; jaws equal; teeth in single 

 series on premaxillaries, of small size, not canine-like; a row of very delicate and 

 minute teeth on lower edge of maxilla, not visible to naked eye as teeth; close-set 

 cardiform series in lower jaw of same size as those on premaxillaries; palatines ridge- 

 like, set on edge with narrow band of similar teeth; gill-rakers 74-19, longest one- 

 third diameter of eye. 



Dorsal inserted over anus, which is midway between edge of opercle and 

 base of middle caudal ray, and its base 2.5 in head; caudal forked, central rays half 

 length of longest, tenth or eleventh ray longest, counting rudimentary rays from 

 either edge; each edge continued on caudal peduncle by a thin fold of skin half-way 

 to last dorsal and anal rays ; anal inserted under third or fourth dorsal ray, and termi- 

 nating a quarter of the length of the eye behind last dorsal ray; both anal and dorsal 

 on fleshy bases; ventral inserted nearly midway between pectoral and anal insertion, 

 its length slightly greater than diameter of eye; pectoral small, 2.8 in head. 



Scales imbricate, deciduous, bases narrower than tips, sides straight; con-
