670 DR. A. GiJNTHER ON NEW FISHES [Nov. 21, 



Nann,ethiops unit^niatus. (Plate LXV. fig. C.) 



D. 13. A. 9. L. lat. 35. L. traiisv. fi/7. 



The height of the body is contained thrice in the total length 

 (without caudal), the length of the head thrice and two thirds. 

 Snout short, shorter than the diameter of the eye, which is one 

 third of the length of the head, and equal to the width of the inter- 

 orbital space. Maxillary very short, scarcely extending to the front 

 margin of the orbit. Intermaxillary with about nine simply notched 

 teeth on each side ; teeth of the lower jaw smaller. The origin of 

 the dorsal fin is midway between the end of the snout and root of 

 the caudal, which is forked. Anal short and low. The root of the 

 ventral is vertically behind the origin of the dorsal. Brownish, with 

 a narrow black band running along the side below the lateral line. 



Gaboon. Several specimens, from 2 to 2| inches long, are in the 

 author's possession, and will be deposited in the British Museum. 



Mormyrus lepturus. (Plate LX1X. fig. B.) 



D. 19. A. 24. L. lat. 44. 



Snout very obtuse, with the mouth terminal, and the upper profile 

 somewhat more curved than the lower ; upper jaw slightly overlap- 

 ping the lower. Eye small, shorter than the snout, situated before 

 the middle of the length of the head. Teeth small, deeply notched, 

 few in number. Pectoral shorter than the head, extending to the 

 middle of the ventral, which is only half as long. 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 longer than the 

 head, and very slender, its depth being one third of its length. 

 Brown, head blackish. Two black vertical bands descend from the 

 origin and end of the dorsal fin to the anal. 



Gaboon. Two specimens, 3 inches long, are in the possession of 

 the author, and will be deposited in the British Museum. 



Belone punctulata. 



D. 21. A. 21. 



The free portion of the tail is slightly compressed, rather deeper 

 than broad ; the lateral line terminates in a distinct heel, which is 

 not coloured blach. The length of the head is contained twice and 

 four fifths in the total (without caudal) ; a deep median groove runs 

 along the median line of the forehead ; crown of the head flat. 

 Maxillary entirely hidden by the praeorbital. The greatest depth 

 of the body is but little less than the length of the postorbital por- 

 tion of the head. Teeth of moderate size ; vomerine teeth none ; 

 tongue smooth. The diameter of the eye is two thirds of the width 

 of the interorbital space, and contained twice and two thirds in the 

 length of the postorbital portion of the head. Ventral fin nearly 

 midway between the base of the caudal and the centre of the eye. 

 Posterior dorsal and anal rays shortest, terminating at some distance 

 from the caudal ; anterior rays of moderate length. Caudal fin
