The head compressed and broad in front, its length equal to 

 the extent of the spinous dorsal, from the base of first to the end 

 of the last spine ; and one-third of the total length without the 

 caudal. The height of the body is contained three and two-thirds 

 in the total length (s. c.) . The diameter of the eye is one-tenth of 

 the length of the head, and is situated close to the front, being 

 only one-fifth of its diameter from the margin of the forehead. 

 Nostrils large, close to the eye. A strong blunt spine on the 

 point or hinder angle of the operculum, reaching to beyond the 

 base of the pectorals, another flat, well-developed spine above it 

 and a little in front of it. The hinder margin of the preopereulum 

 rough, irregularly and coarsely serrated ; the lower margin wavy 

 and irregular, somewhat smooth. Teet;i viliform (no canines) in 

 both jaws, and on a narrow lanceolate band on either side, of 

 the palate ; none on the tongue ; mouth oblique, the length of 

 the upper jaw equal to the width across the mouth, lower jaw 

 the longest. Scales small, narrow, oblong, strongly compressed 

 one against the other, from 120 to 130 on the lateral line, 16-17 

 scales between the lateral line and the fifth dorsal spine. Scales on 

 the head, cheeks, operculum and preopereulum. Branchiostigals 

 seven. Pectoral and caudal fins large, rounded, spotted with 

 blackish, the spinous portion of the dorsal, as measured above, 

 equal to the length of the head ; the first and second spine shorter 

 than the third, the eleventh the longest ; the soft dorsal is well- 

 developed, higher than the last of the spinous portion, and extends 

 almost to the caudal, the membrane indistinctly spotted with 

 blackish.
