half the diameter of the eye. Colours silvery, becoming lightest and glossed with gold below 

 the lateral line. 



ILab. The specimen described is stuffed, and 2O5 inches in length. It was obtained at 

 Tash-kurgan in Sarikol. If this is identical with S. edeniana, M'Clell., it is also found in 

 the Cabul River, in the Mydan Valley, and Sir-i-chusmah.

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

 5J in the length of head, 1| diameter from the end of snout, and also apart. Dorsal profile 

 more convex than that of the abdomen. Upper surface of the head nearly flat ; its greatest 

 width equals its postorbital length, while its height equals its length excluding the snout. 

 Upper jaw rather longer than the lower and overhung by the snout. Mouth: horseshoe-shaped, 

 its gape equalling its cleft. The maxilla reaches to below the hind nostril. Lower labial 

 fold interrupted. Barbels : four ; the maxillary ones two-thirds as long as the eye ; the 

 rostral ones slightly shorter. Fins : dorsal as high as the body below it ; it commences 

 midway between the middle of the eye and the base of the caudal fin ; its last undivided ray 

 is strong, rather coarsely serrated, and nearly as long as the head. Pectoral about as long as 

 the head excluding the snout, and reaching above half-way to the base of the ventral, which 

 latter fin arises below the last undivided dorsal ray, reaching half-way to the base of the 

 anal, which is above twice as high as wide at its base, and nearly reaches the caudal when 

 laid flat. Scales : depth of those in the tiled row scarcely one-third of the diameter of the 

 eye. Free portion of the tail not quite so high at its commencement as it is long. Colours : 

 silvery, with black spots on the upper half of the body. 



This species has a more elevated dorsal profile and shorter barbels than S. intermedius.

Length of head 4| to 5, of caudal 7, height of body 6| to 6| in the total length. Eyes : 

 diameter from 4 to 5^ in the length of the head, 2 diameters from the end of snout, and 

 l apart. The greatest width of the head equals its postorbital length, but is slightly less than 

 its height. Mouth : horseshoe-shaped, with the upper jaw a little the longer, and rather 

 overhung by the snout ; the maxilla reaches to below the front edge of the eye. Lower labial 

 fold very broad, uninterrupted, and with a cleft in the median line posteriorly. Barbels : 

 a pair at the angle of the mouth, which reach the posterior edge of the preopercle ; in a small 

 specimen, 3'1 inches long, they only equal half a diameter of the eye in extent. Teeth : 

 pharyngeal ones in two rows. Fins : the dorsal commences much nearer the snout than the 

 base of the caudal, its entire base being equidistant from these two points ; it has no osseous 

 ray, and is as high as the body below it. Pectoral as long as the head behind the nostrils, and
