Show 788 MR. F. DAY ON THE FISHES OF YARKAND. [Dec. 5, a little oblique, its width equal to its length, and the maxilla reaching to beneath the front nostril. Lips very thick, lobed in the centre, and with an interrupted labial fold. Barbels: the rostral ones reach to below the front edge of the eye; the maxillary ones are one half longer than the diameter of the eye. Fins: dorsal anteriorly about two thirds as high as the body below it; its last undivided ray weak, very feebly serrated posteriorly, whilst the extent of its osseous portion does not exceed one third of the length of the head ; the fin commences midway between the front edge of the eye and the base of the caudal fin. Pectoral as long as the head excluding the snout, and reaching halfway to the ventral, which latter is rather shorter and extends rather more than halfway to the base of the anal. Anal two fifths as long at its base as it is high, when laid flat it almost reaches the caudal, which latter is slightly forked. Free portion of the tail rather longer than high at its base. Scales: those behind the pectoral region to as far as the end of the anal, and below the lateral line, are much smaller than those above the lateral line. The tiled row small, not above half the diameter of the eye. Colours : silvery, becoming lightest and glossed with gold below the lateral line. Hab. The specimen described is stuffed, and 20*5 inches in length. It was obtained as Tash-kurgan. If this is identical with A edeniana, M'Clell., it is also found in the Cabul river, iu the Mydan valley, and Sir-i-chusmah. 8. SCHIZOTHORAX NASUS. Schizothorax nasus, Heckel, Fische Kasch. p. 33. t. vi. ; Gunther, Cat. vii. p. 166. B.iv., D.|, P. 18, V. 10, A. |, C. 19, L. 1. 90-100. Length of head 4f, of caudal 5-J, 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 halfway to the base of the ventral, which latter fin arises below the last undivided dorsal ray, reaching halfway 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 |
