Total length : 1 If inch. 



The length of the head measured to the point of the opercle is a 

 little less than \ of the total, but to the posterior margin of the first 

 interspinal it is ■§■ of the total. The latter bone is narrow rectangular, its 

 breadth being If in its length which is ^ of the distance to the muzzle. 

 The helmet is granulated and partially striated, its anterior two thirds 

 divided by a longitudinal furrow commencing on the forehead on a 

 level with the nostrils. The cheeks and opercles are veined, and the 

 latter also indistinctly radiated. The anterior half of the head is much 

 depressed, the muzzle rounded, truncated. The teeth of both jaws are 

 on narrow bands, card-like and finer than the palatals, which are 

 crowded on a small oval spot on each side. The cirri are slender : the 

 maxillary ones reach to about the middle of the opercle ; the mandibular 

 pairs are nearly equal, f of the former. The eyes are situated at the 

 anterior third of the head, their horizontal diameter is in the young \ 

 in the older \ of the length of the head ; their distance across the 

 forehead is about 4 such diameters. The vertical diameter at occiput 

 is \ of the length of the head ; that in front of the dorsal is a little less 

 than § of the head. The dorsal spine is strong, J of the length of the 

 head, equalling in length the first ray. The posterior margin and that 

 part of the anterior nearest the apex are finely toothed, the rest is granu- 

 lated. The pectoral spine is but f of the dorsal which it otherwise resem- 

 bles, but the teeth of the posterior margin are stronger. The pectorals 

 and ventrals are nearly of equal length or about \ of the length of the 

 head. The extent of the anal equals the greatest vertical diameter of the 

 body ; the length of the eighth and ninth rays is a little less than that
