from the Ogoive River and Old Calabar. 281 



Talagouga, 138 millim. long, but I count only 65 trans- 

 verse series of scales, whilst Sauvage states 82. The diameter 

 of the eye is only one eighth of the length of the head in our 

 specimen. These differences could be accounted for by a 

 somewhat less perfect state of preservation of Sauvage's 

 specimen. 



Mormyrus Kingsleyce, sp. n. (PI. XV. fig. A.) 



D. 17. A. 22. L. lat. 56. 



Snout short, rounded, parabolic, with the small mouth 

 an tero- inferior. Five notched teeth above and six below. 

 The eye is small, half the length of the snout and scarcely 

 one seventh of that of the head. Body rather elongate, its 

 greatest depth being contained 4£ times, the length of the 

 head 4£ times in the total (without caudal). Caudal peduncle 

 compressed, moderately long, shorter than the head, its depth 

 being one half of its length. Origin of the dorsal fin behind 

 that of the anal and twice as distant from the end of the 

 snout as from the root of the caudal. The length of the base 

 of the anal equals that of the head. Pectoral fin shorter than 

 the head, nearly reaching the ventral. Ventral fin more than 

 half as long as the pectoral, and half as long as the distance 

 of its root from the vent. Scales rather small; there are 

 eight in an oblique series running from the first anal ray to 

 the lateral line, and five longitudinal series on the side of the 

 caudal peduncle. Uniform brown.

A single specimen was obtained in Old Calabar. This 

 species is nearest to M. liberiensis (Steind.), but readily 

 distinguished by a shorter anal fin, with a smaller number of 

 rays. 



Mormyrus arnblystoma, sp. n. (PI. XIV. fig. A.) 



D. 24. A. 30. L. lat. 40. 



Snout short, obtuse, as long as the eye, with the mouth at 

 the lower side. The mouth is very broad, twice as broad as 

 the eye, armed above with twenty-two and below with thirty
