Length of head 6, of caudal 6 ; height of body 8 in the total length. Byes : diameter 8 
in the length of head, 3 diameters from the end of snout, and 2 apart. Snout roun< ^ ( ’ 
slightly projecting over the mouth. Lips rugose ; and in some specimens from Yarkand t re 
edges are fimbriated : lower lip with a lobe on either side, hut the lower labial fold interrup 
in the middle. The greatest width of the head equals its height, or its length exchi » 
the snout. In some specimens the preorbital has a free lower edge. Barbels six, . 
maxillary ones reach beyond the hind edge of the eye ; the rostral ones are shorter. -p 
the dorsal commences midway between the eye and the base of the caudal, it is one- 
higher than its base is long, and equals the greatest depth of the body ; its last ray is 1 n * 0llO . 
to its base ; its upper edge is oblique, with a rounded anterior angle. Pectoral nearly, as » 
as the head, and reaching rather above half-way to the ventral ; the latter fin arises 
vertical line below the anterior dorsal rays, is almost as long as the pectoral, and rea • 
above half-way to the anal. Anal with a very narrow base : caudal slightly emarg ^ 
Pree portion of the tail from twice to two-and-a-half times as long as high at its 1 
Scales : absent. Air-vessel : in two portions, enclosed in bone. Colours : greyish alon 
the 
hands- 
back, becoming lighter beneath, marbled all over with dark green or black spots or 
Dorsal, caudal, and sometimes outer pectoral rays barred. 
In specimens from Sarikol the snout is rather more pointed than described above. 
Bab . — Leh (11,518 feet); Snima; Lukong stream (14,130 feet); and Chagra (j^^ 
feet), ail being waters directly or indirectly going to the Indus. Also Yarkand ( ’ ^ 
feet) and Sarikol, where the waters go to the easterly or Yarkand River; and A' 
(12,600 feet), which is on the Aksu or Oxus. _ 
I have a specimen in my collection given me by Dr. Stoliczka : he procured it, 
with those sent to Steindachner, from the Tso-Morari in Rupshu (Tibet), on his fi lS 
to that country.
