 vol. v. p. 435, pi. xvi. figs. 2-4. 



Type. Fish ; British Museum. 



A species of moderate size, attaining a length of not less than 

 0-135. 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 rugge, 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.
