Show 1869.] SURGEON F. DAY ON THE FISHES OF ORISSA. 371 continuous as represented in the figures of those species." The correctness of placing Amblypharynyodon and Thynnichthys as distinct genera is, I think, questionable ; and I am the more confirmed in this belief by an examination of the A. atkinsonii, Blyth (not A. pellucidus, M'Clelland), from Burmah, in which the lateral line is continued for one-third of the length of the body of the fish, or for 19 scales, thus reaching nearly as far as the base of the ventral fin, from which it is divided by six rows of scales. 81. CIRRHINA MRIGALA, H. Buch. Mrigale, Mirrgah (Ooriah). B.iii. D.J. P. 17. V. 9. A.|. C.19. L. 1. 40-43. L. tr. 8^. Differs from the C. leschenaultii, Cuv. & Val., by only having the rostral barbels. In Orissa it appears entirely to supersede the C. leschenaultii, which is a species very common in Madras. Amongst the fishes brought to Calcutta by the late expedition to China are specimens of the C. mrigala, H . Buch., probably identical with C. chinensis, Gunther. 82. CROSSOCHEILUS BATA, H. Buch. Crossocheilus rostratus, Gunther (immature). Dunguda porah (Ooriah). Dommarci batta (Bengali). B. iii. D. 2-f. P. 19. V. 9. A. |. C. 19. L. 1. 36-38. This species I obtained throughout Orissa, as well as from the Cossye, where Dr. Giinther's specimen, 4 inches long, was captured. I have therefore no doubt respecting its identity, although he remarks of the genus, " Barbels two or four; if two, the upper only are present:" and of the species, " two barbels, only shorter than the eye;" whereas in this fish it is the maxillary ones which exist. It loses the black spots on the lateral line more or less completely when it attains a mature state. Being largely domesticated, however, it is subject to certain variations. In one specimen, 10 inches long, the snout was covered with elevated pores, whilst another of the same size, taken along with it, was destitute of them. The number of rows of scales between the lateral line and base of the ventral fin sometimes alters with age. Thus in the immature there are generally four series, but in the adult five. This fish grows to two feet in length. 83. CROSSOCHEILUS GOHAMA, H. Buch. Kala batta (Bengali). B.iii. D.f. P.15. V. 9. A. J, C.19. L. 1. 38-40. L. tr. §. This fish has a distinct lateral lobe to the snout. Hab. Cossye river, at Midnapore. |
