Ahramis tenellus, TsTordmann, in Demid. Toy. Huss. Merid. iii. 

 p. 510 (Cuv. & Yal. xvii. p. 63 ; Kessler, Bull. Soc. Xat. Mosc. 1859, 

 xxxii. p. 529), appears to be closely allied to A. vimhu, and its 

 distinctive characters have not yet been sufficiently pointed out. 

 A. 19-21. L. lat. 50-57. L. transv. 9/7. Pharyngeal teeth 5-5; 

 from rivers near Inkermann. Kessler says that the snoixt is less 

 prominent than in A. vimha, also that Ci/prinns persa, Pallas, Zoogr.

 1837, p. 344), is possibly the same fish.

Body oblong, its depth being one-fourth, or a little less than 

 one-fourlh, of the total length (without caudal). Snout scarcely 

 produced, slightly projecting beyond the mouth, which is entirely 

 at the lower side of the snout. Back of the tail keeled. There 

 are five longitudinal series of scales between the lateral line and the 

 ventral. Anterior anal rays at some distance behind the end of the 

 dorsal fin.

Professor v. Siebold is inclined to regard this fish merely as a 

 variety of A. vimha, representing specimens which, instead of 

 descending to the sea as A. vimha annually does, remain stationary 

 in the rivers. I find that also the skeletons of these two fishes are 

 perfectly identical.
