Length of head from the chin to the opercular margin,, 

 2'5-2'6, depth of body 3'8-3*9 in the length from the chin 

 to the base of the caudal rays. Orbit 1*6-1'7 in the inter- 

 orbital width. The greatest breadth is just behind the pre- 

 opercle, where it is almost equal to the length of the head. 



Head. — Cranial armature sculptured into rounded 

 tubercles ; its hinder margin interrupted by two more or less 

 prominent backward projections, which are extensions of twO' 

 indefinite ridges extending from behind the orbits. The naked 

 cavity between the orbits is subquadrate, but varies in shape, 

 its width being equal to its length in some specimens, and 

 much narrower in others. Eyes superior, surrounded by raised 

 rugose bones ; the postero-exterior angle of the orbit forms: 

 an open hiatus, but the hinder internal portion is complete 

 and rounded. Preorbital bone with several raised ridges, 

 which project as obtuse spines on the margin. Lower border 

 of the preopercle with three strong spines, the anterior of 

 which is directed obliquely forward. Opercle unarmed, its 

 surfaee with radiating, tubercular ridges. Mouth vertical, the 

 lips with rows of short papillae. Maxilla subvertical, broad ; 

 its posterior angle below the middle of the eye when the mouth 

 is closed. 



A short spine projects forward from the lower portion of 

 each ramus of the lower jaw. The skinny folds crossing the-
