riSHES OF LAKE UEMI. 389 



a separate name may be questioned. However, tbe larger size 

 of the scales is so striking a feature, that, without having inter- 

 mediate forms, I think it better to keep the two forms distinct. 

 Telestes leucoides, Filippi, Viagg. Pers. p. 359, from the Baton m 

 Eiver, seems to be also a closely allied species, but is described 

 as agreeing in form with L. aula, which is a fish witb a much 

 higher body. 



Abeamis tjemianus, sp. n. (PI. 23. fig. A.) 



D. 11. A. 14-16 *. L. lat. 58-62. L. transv. 12/8. 



The height of the body is two sevenths, the length of the head 

 one fourth of the total (without caudal). Snout neither pointed 

 nor obtuse, equal to the diameter of the eye, which is one fourth 

 of the length of the head ; interorbital space transversely convex, 

 scarcely wider than the orbit. Cleft of the mouth sligbtly oblique, 

 with tbe jaws equal in front, the maxillary not extending to the 

 vertical from the front margin of the eye. Abdomen rounded iu 

 front, and compressed behind, the ventrals. Caudal peduncle 

 longer than deep. Pectorals not reaching the ventral, shorter 

 than the head. Origin of the dorsal midway between the end of 

 the snout and the root of the caudal. Caudal excision moderate. 

 Pive series of scales between the lateral line and ventral fin. 

 Pharyngeal teeth 5/2, hooked. Silvery, greenish-olive on the 

 back ; sides with numerous minute brownish pigment-spots ; 

 they are more crowded above the lateral line, producing 

 an inconspicuous darker band along tbe whole length of 

 the side. 



Pive specimens from the Grader Chai and two small ones from 

 the TJrmi Eiver ; the largest is only 144 millim. long, but 

 specimens of this size are mature, showing not only fully de- 

 veloped sexual orgatis, but also some of those deep-black spots 

 which appear in so many Cyprinoids during the breeding-season. 

 The gill-rakers are very short, triangular in shape, and widely 

 set, as is characteristic of the genus Abramis, in opposition to 

 Alburnus. 



This species resembles Alburnus punctulatus, Kessler (Aralo- 

 Caucas.-Pont. Ichthyol. p. 159), but has a shorter and smaller 

 anal fin, whilst in the former species this fin is composed of 17 



* 14 in two, 15 in five, 16 in one specimen ; the first three rays being simple 

 in all.
