in the middle. A horny covering to inside of lower jaw. Barbels: the rostral .ones more 

 than half longer than the eye, reaching to below its first third ; the maxillary ones are 

 slightly shorter. Fins : the dorsal as high as the hody ; it commences midway hetween the 

 nostrils and the hase of the caudal ; its last undivided ray osseous, coarsely serrated poste- 

 riorly, and its bony portion being as long as the head, excluding the snout. Pectoral does 

 not quite reach the ventral, which latter fin commences on a vertical line slightly behind 

 the origin of the dorsal, and extends two-thirds of the distance to the anal. Length of 

 base of anal -f of its height ; it reaches, when laid flat, to the base of the caudal, which 

 latter fin is deeply forked. Free portion of the tail as high at its base as it is long. 

 Colours silvery, with numerous black spots, most distinct in the upper half of the body.

Length of head 4, of caudal 5 to 6, height of body 6 in the total length. Eyes : 

 diameter 5J in the length of head, If diameter from the end of snout and also apart. 

 Upper surface of the head flat ; its greatest width equals its postorbital length, whilst its 

 height equals its length excluding the snout. Upper jaw rather longer than the lower, and 

 not overhung by the snout. Mouth horseshoe-shaped, the depth of the cleft equalling the 

 width of its gape. The maxilla reaches to below the hind nostril. Lower labial fold 

 interrupted in the middle. A thin, smooth, deciduous horny covering to the lower jaw. 

 Barbels four, as long as the eye in the young, longer in the adult. Teeth : pharyngeal, 5, 3, 

 2, 2, 3, 5, pointed and rather crooked at their summits. Fins : dorsal as high as the body 

 in the young, not quite so high in the adult ; it commences midway between the end of 

 the snout or front nostril and base of the caudal ; its last undivided ray strong, rather 

 coarsely serrated posteriorly, one-half to two-thirds as long as the head in the immature, four- 

 fifths of its length in the adult. Pectoral as long as the head excluding the snout, and reach- 

 ing more than half-way to the base of the ventral, which latter fin arises below the first dorsal 

 ray and extends more than half-way to the anal. The length of the base of the anal equals 

 half its height, which latter equals the length of the pectoral ; if laid flat it almost reaches 

 the base of the caudal, which is forked. Scales : depth of those in tiled row equals half a 

 diameter of the eye. Free portion of the tait about as high at its commencement as it is 

 ong. Colours silvery, usually without spots ; but in some specimens from Yangihissar there 

 are minute black spots on the upper half of the body. 



Sab. Kashghar, Yangihissar, and Sarikol. M'Clelland Hkewise obtained it (through 

 Griffith) from Afghanistan, the Cabul Biver at Jellalabad, and Tarnuck River. He sent three 

 specimens to the East India Museum.
