Br. 7 ; D. vi. 30-32; A. ii-iii, 28-29 ; V.i, 6 ; P. 19 ; C. 13 ; 

 L. lat. c. 87-93. Height, at origin of dorsal fin, 1.62 in the 

 length to the hypural ; head 2.5 in the same. Length of snout 

 a little less than the iuterorbital width, and 1.79 in the eye ; the 

 latter is 2.14 in the head. Second dorsal spine 2.15, longest 

 dorsal ray 1.26 in the eye. 



The dorsal profile is convex from the snout to a point some 

 distance before the dorsal fin, where it rises more or less obliquely 

 to the base of the first spine. From there it descends rapidly in 

 a slightly convex line to the caudal peduncle. The ventral pro- 

 file is almost similar to that of the back. 



The exposed preorbital, supraorbital and suborbital bones, 

 together with the operculum, preoperculum, suboperculum, 

 mandibular and maxillary are rough with granules and coarse 

 ridges ; the preoperculum and suborbital are perforated by 

 several large pores covered with skin. The interorbital space is 

 bounded on either side and posteriorly by the supraorbital bones ; 

 the median portion is an oblong scaly space which receives the 

 posterior processes of the intermaxillaries when the mouth is 

 closed. The nostrils are large and close together, the posterior 

 the largest and placed directly in front of the eye, they are pro- 

 tected above by a granular bone. Eye extremely large, about 

 once and a half as wide as the interorbital space. The cheeks 

 are covered with scales, each bearing a low elevation in its 

 centre. A few incomplete scales are also present on the lower
