Show 730 DR. A. G D N T H E R O N FISHES [June 6, lations on its upper surface are covered by a thin skin. Occipital process about as long as the basal bone of the dorsal spine, both meeting in the middle of the nape. Snout very long, contained 2^ times in the length of the head, broad, depressed, with the upper profile straight, and with the upper jaw much projecting beyond the lower. Mouth of moderate width, rather less than the distance between the eyes. Nasal barbels nearly as long as the eye; maxillary barbels 'extending to the margin of the pras-operculum, outer mandibulary not reaching the > gill-opening. Inner mandibulary barbels nearly in a straight line with the outer, aud two thirds of the diameter of the eye distant from each other. The vomerine teeth are disposed on each side in two rather broad continuous patches, the halves being separated in front by a toothless space ; the palatine bones are armed with a narrower band-like patch. Intermaxillary band narrowed outward, each half not quite twice as broad as long. The width of the bony interorbital space exceeds that of the orbit, which is contained 2 | times in the length of the snout, and is one sixth of that of the head. Dorsal fin not elevated; its base is two fifths of its distance from the adipose, and double the length of the base of the latter fin. Dorsal spine as long as the head without snout, rather longer than the pectoral spine, smooth in front, and feebly denticulated behind. Anal fin reaching the caudal, when laid backward, with 15 rays, 10 of which are branched, the last split to the base, the first quite rudimentary. Caudal deeply cleft, the upper lobe a little longer than the head. Upper and lateral parts brownish, lower white. Camaroons (Nat. Hist. Mus. 71.11.20.21). Length 600 millim. Intermediate between Ch. cranchii and Ch. nigrodigitatus. EUTROPIUS CONGENSIS (Leach). Two specimens from the Prah River. The anal fin of one with 56, of the other with 59 rays. Feeds largely on macrurous crustaceans. BARBUS TRISPILUS (Bleek.). Puntius (Barbodes) trispilus, Bleek. M e m . Soc. Holl. Haarlem, 1862, p. 113, tab. 23. fig. 3. Two specimens from the Kotchwah River, 27 and 76 millim. long. Relying on Bleeker's description alone, I should have been hardly justified in referring our specimens to his species. He describes it as a large-eyed species, with the eye longer than the snout, the diameter being one third, or a little less than one third, of the length of the bead, aud equal to, or a little less than, the length of the postorbital portion. His specimens measured from 72 to 110 millim.; thus his smaller specimen was almost the same size as our larger one. Nevertheless, I find the eye to be conspicuously smaller, viz., two sevenths of the length of the head and two thirds of that of the postorbital portion. Even our very |
