390 FISHES OF LAKE URMI. 



to 20 rays. The gill-rakers of A. punctulatus are very sliort ; 

 and therefore this species should be referred to Ahramis. A 

 specimen from Tiflis is in the Natural History Museum. 



Albuenus filippii. 



Alburnus filippii, l^essler, in Grimm's Aralo-Caspian Exped.y Pisces? 

 1877, p. 163. 



D. 11. A. 13-14 *. L. lat. (54) 56-60. L. transv. (9) 10/6. 



The height of the bcxdy is contained 4| times in the total length, 

 (without caudal), the length of the head 41 times. Snout rather 

 pointed, equal to the diameter of the eye, which is scarcely one 

 fourth of the length of the head. Interorbital space transversely 

 slightly convex, scarcely wider than the orbit. Cleft of the 

 mouth oblique, with the lower jaw slightly the longer, the max- 

 illary not extending to the vertical from the front margin of the 

 eye. Abdomen rounded in front, slightly compressed behind, 

 the ventrals. Caudal peduncle at least twice as long as deep. 

 Pectorals not reaching the ventral, shorter than the head. Origin 

 of the dorsal nearer to the root of the caudal than to the end of 

 the snout. Caudal excision moderate. Pour series of scales 

 between the lateral line and ventral fin. Pharyngeal teeth f 4/2, 

 liooked. Silvery, olive on the back ; a narrow, straight, well- 

 dehned blackish band from the upper end of the gill-opening to 

 the middle of the caudal fin. 



Three specimens from Sujbulak, the largest 113 millim. long; 

 one specimen from Superghan near the mouth of the JN'azla 

 Chai. 



The gill-rakers are lanceolate, closely set, but the longest 

 scarcely half as long as the eye. 



The specimen from the Nazlu Chai differs slightly from the 

 others, inasmuch as the scales are apparently a little larger ; I 

 count only 54 in the lateral line, and 9 in the transverse series 

 between dorsal fin and lateral line. 



Kessler states that his specimens were obtained from the Kur 

 at Tiflis and at Borjom ; in the fin- formula the number of dorsal 

 rays is stated to be 1/6-7, which would be so abnormal in this 

 genus that I suspect it to be due to soii>e inadvertence. 



* 13 in one, 14 in three specimens, the three anterior rays being simpl?. 

 f Examined in one specimen only.
