Family— CYPliWIDM 
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 base of the anal fin hounded by a row of 
tiled scales, or the ubiquitous Loaches. 
2. Oreinus sinuattjs. 
Only one species of Oreinus exists in this collection, the 0. sinuatus, Heckel, from Leh 
in Ladak, and which has likewise been captured in Kashmir. Although some of the fish 
'vere 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 he worth while drawing attention to the same fact as occurring 
fa specimens of this genus. Thus, in examining the following ten examples of O. richard- 
s °nii, Gray, in the British Museum, I found them as follows : — 
4 specimens, in spirit, from 3'3 to 3'8 inclies in length. Head from 4 to 4§ in the total. 
1 specimen, in spirit, 4 inches in length. Head 4f in the total.

Length of head to 5|, of caudal 6 to 6}, height of body 6^ in the total length. 
-Eyes : Diameter 5-*- (in a fish 7 inches long), 7 to 9 in the length of head, 2 to 2y diameters 
L cm the end of snout, and the same apart. Upper surface of the head nearly flat ; its 
^idth 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 
°fd interrupted in the middle. The maxilla reaches to below the front nostril. The depth 
pf the cleft of the mouth equals the width of its gape. A very thin horny covering to the 
■'Aside of the lower jaw. Posterior edge of opercle cut square. Earbels : the rostral ones 
long as the eye, the maxillary rather longer, sometimes twice as long, and reaching to 
cueath the middle or hind edge of the orbit. Teeth pharyngeal 5, 3, 2, 2, 3, 5 pointed, and 
^i.th rather compressed summits. Fins : the dorsal, which is as high as the body, arises 
’Ridway between the end of the snout and the base of the caudal, its last undivided ray 
osseous, strong, fin ely serrated posteriorly, from a little longer than the head, in a specimen 
1 9 inches in length, to the length in the adult. Pectoral as long as the head excluding 
e snout ; it reaches halfway to the base of the anal. Anal, when laid flat, reaches about
