72 SPOLIA ZEYLANICA. 
C has fifty-one rings, much dilated vertebrally and confluent 
ventrally, corresponding to Boulenger’s variety A (loc. cit.). 
D has forty-four rings, dilated vertebrally and more or less 
confluent ventrally, and is also one of Boulenger’s variety A. 
Distira Jerdoni (Gray). 
Represented by two examples, one adult, one young, both 
labelled No. 123. They are typical. In the larger specimen 
the scales are seventeen behind the neck, nineteen in mid and 
posterior body, and the ventrals are 232. Referred to by Haly 
(Catalogues, 1886, No. 55; and 1891, No. 123). 
Enhydris curtus (Shaw). 
Three specimens are preserved, which agree in the following 
characters :—Rostral : portion visible above about one-third the 
length of the suture between the nasals. Prefrontals touch the 
second labial, except in specimen B, where they meet no labial. 
Postoculars ; one. Labials ; seven or eight, the third and fourth 
touching the eye, except in specimen B, where only the fourth does 
so. Infralabials: the fourth is the largest of the series, and 
touches four scales behind. Sublinguals : too ill-developed to be 
considered as such. Scales; juxtaposed throughout. Ventrals ; 
entire throughout. 
In A specimen the parietal is divided on the left side, but only 
partially so on the right. One marginal is wedged between the 
third and fourth infralabials. 
In B the parietals are broken up into five parts each. There 
are two marginals after the second infralabial. 
In C the parietals are quite broken up. A row of marginals 
succeeds the second infralabial.

Represented by a solitary, small, faded specimen, labelled No. 
119. I cannot trace the other specimens in the collection referred 
to by Haly and Ferguson in their Catalogues, and it is to be noted 
that the Hydrophis cantoris mentioned by Haly (C abMonen 1891, 
No. 120) could not be identitied.
