are not much larger than the neighbouring scales ; few of them are 

 longitudinally divided. Ventrals 4 1 7. Anals four, the outer pair very- 

 large. Sixty-one black bands on the body ; those on the neck con- 

 fluent 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 on 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 pneocular 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 com- 

 plete 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 1 7" 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 

 Gunther. 



Both of these specimens are from a tidal stream in the vicinity of 

 Calcutta.

The specimen in this museum catalogued by Theobald as H. gra- 

 cilis, 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
