The caudal is very slightly emarginate, and has the lobes pointed 

 Ihere are 121 transverse rows of scales, counted immediately 

 above the lateral line ; the series descending obliquely backwards 

 from the origin of the dorsal fin to the lateral line has 30 scales; 

 that from the hinder end of the adipose to the lateral Hne has 16 

 scales; there are 22 long-itudinal scries between the lateral line

The greatest depth of the body is below the origin of the dorsal 

 fan nearly equal to the length of the head, and contained four times 

 and one-third m the total length (without caudal). 



The snout is rather short and obtuse, its length is equal to that of 

 the_ diameter of the eye, and rather less than half of that of the post- 

 orbital portion of the head ; the length of the maxiUary bone is 

 equal to that of the snout together with the diameter of the eye ; its
