Show 1870.] SURGEON F. DAY ON INDIAN FISHES. 373 The species, if it is distinct, which exists in South Canara, is the B. mosal, H. B., whilst I have taken the B. tor in the Bowany and also in Orissa. In the Calcutta Museum are two specimens of the latter variety. The question is, are the B. morsal and the B. tor the same ? and this must be decided by fresh investigations in India. The difference between the two does not depend on age, as I have examined both from 6 to 30 inches in length; neither does it depend on season, which I have not found to exercise any influence: it may be due to sex ; but I doubt it. . The number of rays, scales, and the proportions of the two fishes, posterior to the eye, appear to be identical; but the great differences are in advance of that organ. In the B. tor the snout is pointed and compressed, the lower jaw being the shortest, the mouth is somewhat deeply cleft, whilst cartilaginous thick lips exist in both jaws, forming a lobe above and below; the summit of the head is mostly flattened. In the B. mosal the snout is rounded and not compressed, the jaws of equal length, the mouth is not deeply cleft, and there are no thickened cartilaginous lips. The summit of the head is convex. Both Barbus (Barbodes) conirostris, Giinther, and Barbus (Barbodes) carnaticus, Jerdon, were found to be common in the Wynaad and rivers around their bases. They were also received from Mangalore. It appears not improbable that Barbus mysorensis, Jerdon, is the same as B. conirostris, Gunther. The species I termed B. dubius, I find, has five series of scales between the lateral line and the base of tbe ventral fin. BARBUS (CAPOETA) AMPHIBIUS, C. & V. Systomus carnaticus, Jerdon. Cuvier and Valenciennes have stated their species has no lateral blotch on the side of the tail, whilst the B. carnaticus has one. Having examined several of m y fresh specimens, with an old one in the British Museum, in which the lateral blotch appears to have become bleached, no difference is apparent. BARBUS (CAPOETA) ARULIUS, Jerdon. I find, on examining a large number of fine specimens of this species, obtained in the Wynaad, that it has a maxillary pair of fine long barbels. BARILIUS GATENSIS, C. & V. ? Opsarius malabaricus, Jerdon. Barilius rugosus, Day. Having obtained numerous specimens of this fish from the rivers of the Western Ghauts, whence Cuvier's also were procured, I find it apparently identical with the B. rugosus of the Neilgherries. The remark in Cuv. & Val., however, that the cheek is entirely covered by the suborbital ring, is erroneous; a portion equal to about oue- |
