On the Freshwater Fishes of Burmah. By FRANCIS DAY, F.Z.S., F.L.S.-Part II.* OPHIOCEPHALUS AUROLINEATUS, sp. nov. D. 53. P. 18. V. 6. A. 36. C. 14. L. 1. 66. L. tr. % 14 Length of head nearly |, of caudal T 2^, height of body -fy of the total length. Diameter of eyes ^ of length of head, 1 diameter from end of snout, 11 diameter apart. The posterior extremity of the maxilla extends to below the posterior margin of the orbit. Thirteen rows of scales between the orbit and the angle of the praeopercle. Shields on top of head of moderate size. Teeth numerous, villiform, in jaws, vomer, and palate. Colour dark purplish black, with an orange stripe commencing at the snout and passing through the eye along the side and above the lateral line to the upper half of the tail, Hab. One specimen, 3-j3^ inches, was taken at Moulmein. Although the natives asserted it to be a common species, a second specimen was not obtained. It may prove to be the young of the O. marulius, H. B., from which, however, it appears to differ considerably. LABEO NEILLI, sp. nov. B.iii. D. jg-6. P.15. V. 9. A. 2/5. C.19. L.l. 34. L. tr. ||. Length of head nearly \, of caudal \, height of body f-, of dorsal fin \ of the total length. Eyes. Diameter f- of length of head, 1^ diameter from end of snout, 2 diameters apart. Snout rounded and smooth, it scarcely overlaps the mouth, which is of moderate width; no lateral lobe; lips thin, only slightly reflected, they are both fringed with two, three, or more rows of well-developed papillae internal to the outer fringe. The rostral barbels do not reach the orbit; the maxillary extend to beneath its centre. Body compressed. Fins. The dorsal arises before the ventral, and much nearer the snout than the base of the caudal, which latter is deeply forked. Upper margin of dorsal slightly concave. Teeth pharyngeal, 5, 4, 3/3, 4, 5, plough-shaped. Scales. Four and a half rows between lateral line and the base of the ventral fin. Gill-rakers very short. * For Part I. see P. Z. S. 18H9, p. C>14. |
