Body elongate, rather depressed anteriorly, well compressed 

 from vent back. Caudal peduncle rather slender, its least 

 depth twice its length. Head rather robust, depth about 7/8 

 its width. Snout not especially depressed, length about half 

 its width at front edge of eyes. Eyes large, rather close to- 

 gether, hind edge near middle of head length. Mouth mod- 

 erate, lower jaw slightly projecting. Narrow band of fine 

 teeth in each jaw and row of small ones transversely on vo- 

 mer, but none on palatines or tongue. Maxillary small, reach- 

 es back opposite middle of eye. Interorbital concave. Pre- 

 opercle with a spine nearly as long as pupil curving up back- 

 ward. Gill-rakers tubercular, only about 5, obsolete, on lower 

 branch of first gill-arch. Branchiostegals 7. Skin largely 

 smooth. L. 1. high at shoulder, slopes down till median above 

 anal, and front tubes somewhat enlarged. Mandible and pre- 

 opercle rather cavernous. Spinal dorsal begins close behind 

 head, fin apparently low (damaged). Second dorsal begins 

 slightly before anal origin, fins alike. Caudal apparently trun- 

 cate or slightly rounded behind. Pectoral rays 13, all simple 

 and lowermost a little stronger, reaches back nearly opposite 

 vent. Ventral inserted about opposite base of lowermost pec- 

 toral ray, with one spine and four rays which reach 2/3 to 

 vent. Latter close before anal.
