Show 1867-] MR. F. DAY ON NEW INDIAN FISHES. 699 phalanges of four digits of manus 2, 2, 3, 2, of five digits of pes 2, 2, 3, 4, 2; no fold in front of the cloacal aperture; tail rather thick, yet compressed at base; no parotids ; twelve costal folds on each side between axilla and groin ; palatine teeth forming a transverse, slightly undulating, but subcontinuous series; no sphenoidal teeth ; muzzle not projecting beyond the end of the mandible; tongue entirely fixed, behind as well as in front, and only somewhat free at each side; no postorbital arch or process (?); two premaxillae (?) ; carpus and tarsus ossified (?). Hab. Laos Mountains ? Thus, if the generic distinctness of this form is to be considered established, we shall have that degree of relationship to American forms which, under the circumstances above mentioned, is not anomalous, while we shall not have that close affinity to a peculiarly American form which was at first suspected to exist, and which would be so very anomalous if found in a species belonging to the true Indian region, whence P. persimilis was at one time supposed to have come. 4. O n some N e w or imperfectly known Fishes of India. B y Surgeon F R A N C I S D A Y , F.Z S., F.L.S., Principal Medical Storekeeper, Madras Army. During the last month I have obtained the following species of fish, amongst many others, from the sea and fresh waters in the neighbourhood of Madras. SERRANUS RADIATUS, sp. nov. B.vii. D. 11/15. P. 19. V. 1/5. A. 3/8. C. 15. L.l. above 120. Length of specimen 4 inches. Length of head \, of pectoral |, of base of dorsal spines f, of base of dorsal rays \, of base of anal \, of caudal i of the total length. Height of head f, of body f, of dorsal spines §, of dorsal rays \, of ventral T 2 T, of anal \ of the total length. Eye transversely oval, its upper margin near the profile ; diameter -2- of length of head, 1 diameter from end of snout, | a diameter apart. General appearance rather elongated, and the dorsal profile slightly more convex than the abdominal. Lower jaw the longest; the posterior extremity of the upper jaw reaches to beneath the posterior margin of the orbit. Praeopercle slightly oblique posteriorly, which is serrated, three strong denticulations at its angle, its horizontal margin entire. Sub- and inter-opercles entire. Opercle with three flat spines, the central one of which is the longest. Teeth in strong recurved villiform rows in both jaws, and a canine on either side of the centre of the upper. Teeth on vomer and palate in villiform bands, but much smaller than those in the jaws. |
