Sixty-one black bands on the body ; those on the neck confluent with the black under surface of that part of the body ; those on the back extending only on to the side. Head black ; tail with seven black bars. General colour (in spirit) above pale olive-grey ; dirty yellow on the sides and under surface, except the slender part of the body. Length 38" 6'", tail 2" 7"'. With the exception of the absence of light keeling ou the dorsal scales, this specimen agrees in every particular with this species. HYDROPHIS CORONATA, Gthr. I. c. p. 372. This specimen is 42" 3'" in length, tail 3" 9'". Twenty-one rows of scales round the neck ; imbricate, those on the back keeled, and those of the side with a small tubercle. Ventral shields about twice as large as the surrounding ones, with two minute tubercles on each ; the rostral is much broader than long ; and the third labial is not in contact with the nasal. One praeocular and postocular; three large tubercles along the side of each occipital; two pairs of chin-shields in contact with each other. There are fifty-eight complete blackish rings round the trunk, and eight black bars on the tail. In this specimen there are six anal shields, the two outermost ones being the largest; but in a specimen measuring 17" 8'", tail 1" 10'", there are only four anal shields, the external ones being much larger than the others. It has, however, only forty-seven complete black rings on the trunk, and nine black bars on the tail. The coloration of the head and of the ventral surface of the long whip-like anterior portion of the body is the same as described by Giinther. Both of these specimens are from a tidal stream in the vicinity of Calcutta. HYDROPHIS CANTORIS, Gthr. I. c. p. 374. Hydrus gracilis, Cantor, Mai. Rept. p. 130 (not synon.). ? Liopola fasciata, Gray, Zool. Misc. p. 60 (young) (not Schneid. nor Shaw). Hgdrophisgracilis, Shaw; Theob. Cat. Rept. As. Soc. Mus. 1868, p. 68. The specimen in this museum catalogued by Theobald as H. gracilis, Shaw, is undoubtedly of this species. The upper jaw hardly projects beyond the lower one; and the rostral is prolonged backwards, and is not cutting in front. The third labial is in contact with the nasal; and there are two large temporals alongside of the occipital, one prae- and one postocular, and two pairs of chin-shields, in contact with each other. There are twenty-three rows of scales round the neck, which is very slender and nearly one-half of the length of -the body. In the narrow part of the body the ventrals are twice the size of the neighbouring scales; and in the thick portion they are |
