Body compressed, slightly elevated, its greatest depth being one- 

 fourth of the distance of the snout from the end of the middle caudal 

 rays ; the length of the head is scarcely more than one-half of the dis- 

 tance between the snout and the vertical from the origin of the dorsal. 

 Head compressed ; interorbital space convex, its width being less 

 than twice the diameter of the eye. Jaws of the male of equal length 

 anteriorly ; lower jaw very feeble. Teeth very small, four in each 

 intermaxillary, and about sixteen in each maxillary. Length of pec- 

 toral equal to, or rather moie than, that of the head, terminating at 

 no great distance from the ventral, and extending to, or beyond, the 

 origin of the dorsal. Sides with scattered light-orange-coloured dots ; 

 beUy uniform silvery whitish, or with a light-reddish shade ; fins 

 blackish.

Description of a Male specimen, 11 inches long. 



Head and body compressed, slightly elevated, its greatest depth, 

 which is below the origin of the dorsal fin, being contained four 

 times in the total length (to the end of the middle caudal rays). The 

 least depth of the tail is considerably less than the length of the base 

 of the dorsal fin. The height of the head above the mandibulary 

 joint is more than the distance between the posterior margin of the 

 orbit and the end of the operculum. The upper profile of the head 

 is elevated above the margin of the orbit, the diameter of which is 

 one-fifth of the length of the head, shorter than the snout, and a
