ICHTHYOLOGY. 3 



Family CYPR1NIVM 



The majority of the fishes in the collection consist of carps, those from the more elevated 

 regions being confined to such as have the vent and hase of the anal fin bounded by a row of 

 tiled scales, or the ubiquitous Loaches. 



2. OREINTJS SINTJATTJS. 



Only one species of Oreinus exists in this collection, the O. sinuatus, Heckel, from Leh 

 in Laddk, and which has likewise been captured in Kashmir. Although some of the fish 

 were obtained in Kashmir, where the genus Oreinus has representatives, there was no example 

 from that locality. 



Having observed upon the great variation in proportions existing in a species of Exostoma 

 captured on the hills, it may be worth while drawing attention to the same fact as occurring 

 in specimens of this genus. Thus, in examining the following ten examples of 0. richard- 

 sonii, Gray, in the British Museum, I found them as follows : 



4 specimens, in spirit, from 3'3 to 3'8 inches in length. Head from 4 to 4f in the total. 

 1 specimen, in spirit, 4 inches in length. Head 4j in the total.

Length of head 4f- to 5-|, of caudal 6 to 6, height of body fr*- in the total length. 

 Eyes : Diameter 5j- (in a fish 7 inches long), 7 to 9 in the length of head, 2 to 2 diameters 

 from the end of snout, and the same apart. Upper surface of the head nearly flat ; its 

 width rather exceeds its height, and equals half its length. Snout rather compressed, and 

 overhanging the upper jaw. Mouth directed forwards, horseshoe-shaped, the lower labial 

 fold interrupted in the middle. The maxilla reaches to below the front nostril. The depth 

 of the cleft of the mouth equals the width of its gape. A very thin horny covering to the 

 inside of the lower jaw. Posterior edge of opercle cut square. Barbels : the rostral ones 

 as long as the eye, the maxillary rather longer, sometimes twice as long, and reaching to 

 beneath the middle or hind edge of the orbit. Teeth pharyngeal 5, 3, 2, 2, 3, 6 pointed, and 

 with rather compressed summits. Fins : the dorsal, which is as high as the body, arises 

 midway between the end of the snout and the base of the caudal, its last undivided ray 

 osseous, strong, finely serrated posteriorly, from a little longer than the head, in a specimen 

 11' 9 inches in length, to the length in the adult. Pectoral as long as the head excluding 

 the snout ; it reaches halfway to the base of the anal. Anal, when laid flat, reaches about
