DESCRIPTION OF 
a half. Circumference, (near the head,) one inch and a fourth ; the rest of the trunk, about 
two inches and a half. The tail short, sharp pointed; in length, three inches and a half. 
The predominant colour, a duskish clay. On the neck, a remarkable oblique, broad, 
black, mark, with a waving, yellowish, or white, margin, of a triangular shape, the point 
towards the occiput. The trunk and tail are variegated with two or three and twenty cross 
bands, with similar borders, which continue bright in colour to the end of the tail. 
OBSERVATIONS. 
This snake, without a name, was sent from Arnee, by Major Bonniveaux, and received 
in October, I 7 8 S. 
If it is not the same species with No. XXXV. it certainly bears a strong resemblance. 
The two remarkable fillets on the head are, however, wanting here, and the mark on the 
neck, differs in shape from the third fillet in the former: but the cross bands on the trunk, 
are nearly alike both in shape and colour; the number of the latter, however, instead of 
thirty-four, is only twenty-two, and the difference of the united scuta and squamae is 
twenty-four. Another circumstance in which they differ, is the form of the scales; in the 
former they were sub-orbicular, here they are ovate.

A description of this Bengal snake, with a sketch of the head and tail, was received from 
Mr. Alexander Russell, of Calcutta, in June, 1 7 88. 
The head a little broader than the neck, oblong, depressed, the rostrum sub-compressed, 
very obtuse. The hind head covered with very small, ovate, scales; the rest, with a num¬ 
ber of laminae, as represented in the figure. 
The mouth wide, the jaws equal. The teeth in the lower jaw large, reflex, sharp; in 
the upper jaw, a marginal row, and two palatal rows, as in the serpents that have no flings. 
The eyes lateral, orbicular, large. The nostrils , very near the point of the rostrum. 
The trunk? ound, covered with small, smooth, oval, scales, closely imbricate: but there are 
two rows of larger scales on each side of the belly. The scuta are remarkably short; and a 
little above the anus, on each side, is a small spur, about the fourth of an inch in length, of 
a horny texture, curve, with the sharp point turned outwards.
