18/6.] MR. F. DAY ON THE FISHES OF YABKAND. 787 



Jellalabad, and Tarnuck river. He sent three specimens to the 

 East-India Museum. 



6. SCHIZOTHORAX MICROCEPHALUS, Sp. nOV. 



B. iv., D. §, P. 18, V. 1 1, A. |, C. 18, L. 1. 105, L. t. 25/. 



Length of head 5 to 5^, of caudal 6, height of body 5| to 6 in 

 the total length. Eyes : diameter 7 in the length of head, 2| diameters 

 from end of snout, and 2\ apart. Interorbital space flat. The 

 greatest width of the head equals its length behind the middle of 

 the eyes ; its height equals its length excluding the snout. Mouth 

 broad, anterior, with the upper jaw the longer, and overhung by the 

 snout ; the cleft of the mouth nearly horizontal, it extends to below 

 the hind nostril, and is scarcely above half the extent of its gape ; 

 lower labial fold interrupted in the middle. A thin horny covering 

 to the lower jaw. Barbels : the rostral ones reach to below the 

 hind edge of the eye, the maxillary ones to the hind edge of the 

 preopercle. Fins : dorsal anteriorly nearly as high as the body, 

 commencing slightly nearer the snout than the base of the caudal 

 fin, or midway between the two ; its last undivided ray weak, arti- 

 culated, and with some very small obsolete denticulations posteriorly 

 about its centre (absent in some specimens). Pectoral as long as 

 the head behind the front nostril, and reaching rather above half- 

 way to the ventral, which latter is shorter than the pectoral, 

 reaching about halfway to the base of the anal. Anal almost reaching 

 base of caudal when laid flat, the length of its base being only one 

 third of its height. Caudal with rounded lobes. Free portion of 

 the tail rather longer than high. Scales: in the first third of the 

 body those along the lateral line are larger than those above or below 

 them, but posteriorly they are of the same size ; the tiled row equal 

 about half the diameter of the eye. Co/ours silvery. 



M'Clelland says of S. ecleniana that its spine is slender, soft, and 

 denticulated at its base, but the reflected fold of the lower lip 

 is uninterupted. Racoma yobioides, M'Clell., from the Bamean 

 river, shows the head almost as short as in this species ; but it has a 

 strong serrated dorsal spine, whilst that fin is on an elevated base. 

 The anal does not appear to reach above halfway to the base of the 

 caudal. 



Hab. The specimens are from Panja (9000 feet), the waters going 

 to the Oxus. The dorsal spine approaches that of Ptychobarbus. 



7. SCH130TH0RAX IRREGULARIS, Sp. nOV. 



1 Schizothorax edeniana, M'Clell. Calc. J. N. H. ii. p. 579. 



B. iv., D. f, P. 18, V. 9, A. I C. 20, L. 1. 98, L. tr. 26/. 



Length of head 5, of caudal 6, height of body 6 in the total 

 length. Eyes: diameter 6| in the length of head, 2| diameters 

 from the end of snout, and about 2 apart. Interorbital space nearly 

 flat. The greatest width of the head equals its height or its length 

 behind the orbit. Mouth narrow ; the upper jaw slightly the 

 longer, and only slightly overhung by the snout. Cleft of mouth
