Show .] MR. F. DAY ON THE FISHES OF AFGHANISTAN. 225 about 5900 feet, the slope of the latter place being, as observed, towards the Helmund. Griffith's examples of fishes were, unfortunately, all or nearly all destroyed ; but he had figures made, and determined them to be as follows:-in the Bolan Pass-Barbus (1 B. terio), B. tor, Opsarius (. Chela bacaila), Labeo diplostomus, Gonorhynchus (? Cirrhina latia), Silurus kugejur, 1 Macroejnathus (Mastacembelus armatus); from a stream at Gurmah flowing into that of the Bolan-Barbus tor, B. (IB. terio), Gonorhynchus (? Cirrhina latia), Systomus bimaculatus (never described if new), S. canius (this cannot be Barbus canius = B.gelius, as the species does not extend so far, but it may be B. ticto) ; at Quetta he obtained a Barbus with bright red streaks (1 Scaphiodon microphthalmia), two other Cyprinidse (ISca-phiodon irregularis and Barbus milesi), a Gonorhynchus (I Cirrhina latia), and a Loach (Nemacheilus). Doubt may exist as to the identity of some of these species ; but as my examples from Quetta agree in number with those discovered by Griffith, it does not seem improbable that we may be both alluding to the same forms. I will therefore now pass on to descriptions of such fishes as I have received from Gwadur in Beluchistan and the range of hills terminating at Quetta. OPHIOCEPHALUS GACHUA, Ham. Buch. Colonel Miles sent me some small examples from a river near Gwadur; it has likewise been recorded by Griffith that " two species of Ophiocephalus are found at Jellalabad which are unknown in Bengal." These two species were described as Ophiocephalus indicus and 0. montanus, M'Clelland. Of the former, two examples, viz. from Loodianah and Seharanpore, exist in the British Museum, and are specimens of 0. punctatus, which leads one to the conclusion that the Jellalabad fish was the same; while O. montanus, M'Clelland, is identical with O. gachua, the type (from Afghanistan) being stuffed and in the British Museum. CALLICHROUS PABDA, Ham. Buch. Silurus anastomus, Cuv. & Val. S. lamghur, Heck el. Callichrous vittatus, Swainson. Cryptopterus latovittatus, Playfair. Callichrous egertonii, Day. M y reasons for uniting these forms into one species I have fully detailed in my ' Fishes of India,' p. 479; and, admitting they are all identical, the range of the species is very wide : Griffith found one of this genus in Afghanistan ; and such may have been identical with the beautiful example 5| inches in length sent by Dr. Duke. Its pectoral spine is rather strong and serrated. Griffith obtained from the Cabul river at Jellalabad an example of " a Silurus very like, if not identical with, the Poftah." All the species of Callichrous are known as "Poftah ;" therefore it does not appear improbable that it may have been this form which was obtained at Jellalabad, especially as the river eventually finds its way into the 15* |
