ICHTHYOLOGY. 3 
Family— CYPE1NIDJE 
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. Oreintjs sintjatus. 
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 
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 O, richard- 
sonii , 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 tire total.

B. iii. D. , P. 18, V. 10, A. f, C. 20, L. 1. 110 to 120. 
Length of head 4f to 5|, of caudal 6 to 64, height of body 64 in the total length. 
Eyes: Diameter 5|- (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. Hpper 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, 5 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 f- 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
