 scales of lateral line 58. Body rather robust, not much compressed; head 

 broad ; interorbital area flat, its width 3 in head ; eye rather small, its diam- 

 eter 3| in head; snout father blunt, its length equal to diameter of eye; 

 mouth large; length of maxillary 4 in head. Pectoral fin broad and
