Show 190 DR. J. ANDERSON ON INDIAN REPTILES. [Feb. 21, at the same time, Giinther stating that his eight specimens show the same assemblage of characters as laid down in his description, the occurrence of fifty-six rings in m y specimen suggests that this multiplicity is either due to greater age (for it measures 49 inches in length) or to variation. The head, too, is wholly black, with the exception of a yellow band from the posterior margin ot one eye to the other. The upper surface is olive-green, and the sides and belly rich dark gamboge-yellow, and the fifty-six rings are intensely black, and the scales generally have a very bright shining lustre. Fallahs Mullah, a tidal stream, Calcutta. If this form should prove to be new, I would indicate it as P. affinis, n. sp. HYDROPHIS GRANOSA, n. sp. Hydrophis gracilis, Shaw; Theobald (in part.), Cat. Rept. As. Soc. Mus. 1868, p. 68. Anterior part of the body moderately slender ; head rather tapering and laterally compressed. Two labials below the eye; third labial widely separated from the nasal by the second labial, frontal, and pras-ocular ; one large anterior temporal, with two smaller ones behind it; one praeocular and one postocular ; one pair of round scales like chin-shields not in contact with each other or with any of the labials. Forty-three rows of scales round the neck. Scales small, with a prominent keel slightly dilated at either extremity; the scales are elongately leaf-shaped and markedly imbricate on the slender portion of the body, but on the thick portion behind they me truncated at their tips and less imbricate; the scales immediately behind the head, and the shields of the head generally, and the scales on the lower jaw, are covered with minute rounded granular tubercles, which are especially numerous on the rostral. The ventrals are twice the size of the neighbouring scales, and are of a uniform size throughout, and those of the thick part of the body are not split; each carries from two to four small tubercles, usually arranged m pairs, two large ones anteriorly, and two smaller ones posteriorly, and external to the latter. Six anal shields, the outer one very large, and equal to two of the others in size. Ventrals 105. Terminal scale of the tail small. Fifty-two non-confluent black bands on the body, extending down the sides, but not reaching the ventral surface; eight black bars on the tail. The ground-colour in this spirit-specimen is pale yellowish. It was obtained at the Sand Heads. The number and character of the scales of this Snake and the scale-like nature of its chin-shields seem to indicate that it is closely allied to _7. stokesii, a species which I have never seen. "y some of its characters it is also allied to H. ceerulescens, Shaw. HYDROPHIS JERDONII, Gray • Gthr. I. c. p. 362. Total length 381 incbes> tail 3%. In this specimen there are forty |
