ICHTHYOLOGY. 7 
half the diameter of the eye. Colours silvery, becoming lightest and glossed with gold below 
the lateral line. 
Sab. The specimen described is stuffed, and 20*5 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 My dan Yalley, and Sir-i-chusmah.

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

Length of head 4f to 5, of caudal 7j, height of body 65 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 
1J 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, 8 T 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
