Head 3i in adult male; depth 4; eye 5|; D. 8; A. 8; scales 10-75-9, 32 

 before dorsal ; teeth 4-4. Body stout, moderately compressed ; head large, 

 conical, with large tubercles, each with a central spine; mouth small,

 in head. Dorsal fin opposite ventrals, its first ray \ distance from snout to
