Show 554 SURGEON F. DAY ON INDIAN FISHES. [Nov. 25, Fins. Pectoral and ventrals horizontal, the former arising under the opercles and extending to the latter, its first ray only is undivided and reaches the anal; the anterior portion of the pectoral and ventral fins are enveloped in thick skin. Dorsal arises in advance of the ventral. Caudal slightly forked. Scales on body, none on the chest, nor so far as the posterior margin of the base of the pectorals. Lateral line consists of a single tube in each scale ; it passes direct to the centre of the base of the caudal fin. There are 2 | rows of scales between it and the base of the ventral fin. Colours. Greenish brown, no markings visible except a dark blotch behind the opercle. Two specimens exist in the Calcutta Museum, 3^ inches long, from Northern India. DISCOGNATHUS LAMTA, Ham. Buch. Dr. Giinther, in his ' Catalogue of Fishes,' vol. vii. p. 69, observed that " this species extends from Syria to Assam," and, " having fortunately examples from the most distant localities, I have convinced myself that they ought to be referred to a single species only." If all the different species referred to by Dr. Gunther are one, then the Platycara notata, Blyth, is only a synonym ; it differs only in having a black spot at the base of each dorsal ray. Specimens apparently of this species are also in the collection, which were obtained in the Abyssinian expedition-six from the Sooroo Pass, 2000 feet above the level of the sea, and six more from the A m b a Pass. None are above 2 inches in length. CROSSOCHEILUS MOSARIO. Cyprinus mosario, Ham. Buch. B. iii. D. 2/9. P. 17. V. 9. A. 2/5. C. 17. L. 1. 37. L. tr. £.
