Type. Pish; British Museum. 
A species of moderate size, attaining a length of not less than 
0T35. Maximum depth of trunk equalling the length of the head 
with opercular apparatus, and comprised about four and a half 
times in the total length. Teeth regularly spaced, slender, and 
curved ; cranial and facial bones ornamented with coarse rounded 
tubercles, rarely elongated and fused into short rugae, becoming 
sparse on the opercular bones ; suboperculum deeper than broad, 
much larger than the operculum. Pelvic fins relatively large, 
arising nearer to the anal than to the pectorals; anterior rays.of 
median fins robust and covered with smooth ganoine; dorsal fin 
arising at the middle point of the back, opposite the hinder half of 
the pelvic fins, the length of the fin equalling its maximum depth, 
which is much less than that of the trunk at its point of origin ; anal 
fin relatively small and low, its height equalling only half that of 
the dorsal, and its length being only about three-quarters that of 
the latter. Scales small, externally ornamented with numerous 
irregularly arranged tubercles.
