B. iii, D. g, P. 19, Y. 9, A. f, C. 19, L. 1. 80-90. 
Length of head 5 to 6, of caudal 5 to 6; height of body 7 J to 8 in the total length. 
Eyes: diameter 4| in the young to 6 in the adult in the length of the head, 1J to 2 diameters 
from the end of snout, and apart. The greatest width of the head equals its height, or its 
length behind the front edge or middle of the eyes. Mouth transverse, inferior, having an 
anterior sharp horny covering on the lower jaw. Lower labial fold interrupted in the middle. 
Barbels: one at each maxilla, having thick bases, and hardly so long as the eye. Teeth 
pharyngeal, 4, 3, 3, 4, curved at the outer extremity and pointed. Fins: the dorsal 
commences rather nearer the snout than the base of the caudal, its upper edge is straight; 
it is as high as the body below it, its last undivided ray articulated. Pectoral not quite so 
long as the head; it reaches rather above half-way to the ventral, which latter commences 
on a vertical line below the last dorsal ray; it reaches rather above half-way to the base of 
the anal. Anal when laid flat reaches the base of the caudal; its height is nearly three 
times the length of its base. Scales not imbricated, but scattered over the upper two- 
thirds of the body and pectoral region, in which latter locality the skin is often rugose: 
the tiled row well developed. Eree portion of the tail one-half longer than high at 
its base. Colours bluish, lightest inferiorly, indistinctly blotched and spotted along the 
upper half of the body; often a narrow, dull band along the lateral line, and a second 
below it. The dorsal and caudal fins much spotted in some specimens. 
The very young are destitute of scales; they first appear along the lateral line. One 
specimen from Basgo, IT inch long, has no barbel on the left side. There are two specimens 
from the west of Sarikol: one has an adipose lid, covering the anterior half of the left eye ; 
the other has a similar lid covering the lower half of the left eye. Brown tubercles are com¬ 
mon on some of the specimens, and do not appear to be normal. Some specimens from Leh 
have the eye small. 
Diptychus severzowi, from the Divers Aksai and Ottuck appears to be the above species. 
FLab. Specimens were brought from Kharbu, Basgo, Snima, Leh, Tankse, and Chagra, 
from waters going directly or indirectly to the Indus; from Pasrobat (9,370 feet), and 
Tarbashi (11,515 feet), whence the waters go to the Yarkand Diver; also from west of 
Sarikol, which goes to the same river. Some specimens are also labelled as from Chiliscomo. 
This fish has also been captured in other parts of Tibet, and likewise in Nepal.
