nSHES or LAKE IJEMI. 3S5 



seems to be distinguished (if we judge from the figure) from our 

 G. gracilis by a greater number of scale-rows between lateral 

 line and ventral fin. It is said to have one or two pairs of 

 barbels. The specimens were from the Eiver Sarefschan. 



Pilippi's description of his Cajpoeta sevangi from Lake Gokcha 

 contains nothing by which we could distinguish this fish from 

 C. gracilis. But the fish described and figured under the name 

 of C sevangi by Kessler * is certainly distinct from our C. gracilis. 

 As, according to Kessler's investigations t, Lake Gokcha is in- 

 habited by several species of Capoeta, we are left in uncertainty 

 as to whether the fishes named sevangi by Eilippiand Kessler are 

 specifically the same. 



ScapModon sieholdii, Steindachner, is described from a speci- 

 men 133 millim. long. The eye is noted as of somewhat larger 

 size than in our specimens, but the comparative size of this 

 organ is subject to the usual changes with the growth of the 

 individual.

The height of the body is contained 5| or 5| times in the total 

 length (without caudal), the length of the head 4^ or 4| times. 

 The diameter of the eye is one half of the length of the snout 

 and two elevenths of that of the head; interorbital space not 

 quite twice as wide as the eye. Anterior barbels a little shorter 

 than posterior, which are not twice as long as the eye. Caudal 

 peduncle longer than deep. Dorsal spine rather feeble, but 

 finely serrated behind, somewhat neai'er to the root of the caudal 

 than to the end of the snout, opposite to the root of the ventral. 

 Anal fin not reaching to the caudal. Caudal slightly emarginate, 

 but in young examples (of 110 millim.) the excision is deeper. 

 Pectoral shorter than the head, rounded. Eleven longitudinal
