I described this species from two young specimens 3 inches 

 long. ]\liss Kingsley has rediscovered it at Talagouga, and 

 collected specimens apparently adult and up to 190 millim. in 

 length. Thus I am enabled to amend my original diagnosis 

 in several points. 



D. 20-24. A. 25-29. L. lat. 42-44. 



Snout obtuse, with the mouth terminal and, with age, with 

 the lower lip thickened into a short adipose protuberance. 

 The upper profile is somewhat more curved than the lower. 

 Eye small, shorter than (in adult specimens only half as long 

 as) the snout, situated in the anterior half of the head. 

 Teeth of moderate size, notched, few in number. The height 

 of the body is two sevenths of the total length (without 

 caudal), the length of the head two ninths. The caudal 

 peduncle is slender, about as long as the head, its depth being 

 one third of its length. Origin of the dorsal fin a little 

 behind that of the anal, midway between the root of the 

 caudal and the head. Pectoral a little shorter than the head, 

 extending to the middle of the ventral, which is only half as 

 long and terminates a long way from the vent. The scales 

 on the anterior part of the trunk are of moderate size ; they 

 gradually increase in size towards behind, and are largest on 

 the hinder part of the tail and on the caudal peduncle, on the 

 side of which they stand in three series. Brownish or 

 silvery, darker on the head. Two black vertical bands 

 descend from the anterior and hindmost dorsal rays to the 

 anal, spreading more or less over that fin. 



Mormyrus sphecodes.

The teeth on the palate and tongue are well developed. 

 Sauvage's description is fairly applicable to a specimen from
