796 MR. F. DAY ON THE FISHES OF YARKAND. [Dec. 5, 



Colours : greyish along the back, becoming lighter beneath, marbled 

 all over with dark green or black spots or bands. Dorsal, caudal, and 

 sometimes outer pectoral rays barred. 



In specimens from Sirikol the snout is rather more pointed than 

 described above. 



Hub. Leh or Ladak (1 1,538 feet) ; Sneema, Lukung stream 

 (1-4,130 feet) ; and Chagra ( 15,000 feet), all being waters directly 

 or indirectly going to the Indus. Also Yarkand (3923 feet) and 

 Sirikol, where the waters go to the easterly or Yarkand river; and 

 Aktash (12,600 feet), which is on the Aksi, a tributary of the Oxus. 



I have a specimen in my collection given me by Dr. Stoliczka ; he 

 procured it, along with those sent to Steindachner, from Lake Tsu- 

 mureri in Rupshu (Tibet), on his first visit to that country.

Length of head -4^, of caudal 6, height of body 6f in the total 

 length. Eyes: diameter 6 to 7 in the length of the head, 2h dia- 

 meters from the end of snout, and 2 to 3 apart. Snout rather 

 elevated in the adult : upper surface of the head nearly flat ; its 

 greatest width equals its height or its length excluding the snout. 

 Mouth inferior, horseshoe-shaped ; lips smooth, lower labial fold 

 interrupted in the middle and destitute of lobes. Barbels six ; the 

 maxillary ones reach (in adults) the angle of the preopercle. Fins : 

 the dorsal commences midway between the front edge of the eye 

 and the base of the caudal fin ; its upper edge is straight and 

 oblique ; its height rather exceeds that of the body below it, and is 

 one fourth more than the extent of its base. Pectoral as long as 

 the head excluding the snout, and reaching two thirds of the distance 

 to the ventral. Ventral commences below the first dorsal ray, is 

 shorter than the pectoral, and reaches two thirds of the distance to 

 the anal. Anal twice as high as wide at its base. Caudal emar- 

 ginate, its outer rays being a little produced. Free portion of the 

 tail at its commencement nearly equals its length in the adult, but is 

 less in the young. Scales absent. Air-vessel in two portions, en-
