No. XIV.—ON THE BREEDING HABITS OF HYPS/RHINA 
ENEYDRIS AND HERPETON PENTCAULATUM 
(THE TENTACLE SNAKE). 
Hypsirhina enhydris. The following observations confirm and 
supplement what is already known about the breeding habits of this 
' species. 
I obtained a female in the month of December showing enlarged 
ovarian follicles, in which the embryos, 10 in number, could be just 
discerned. | received another gravid female in April, containing 18 
young ones, their development in this case being well advanced. ‘The 
mother was a very large specimen measuring 680 mm. in length. A 
third was caught in July, which gave birth to a single still-born young 
one, probably the last of her brood. The other records, quoted by Major 
Wall in his article on this snake in the Journal of the Bombay Natural 
History Society, are as follows :—‘‘ Colonel Evans came across a pair im 
copula in Lower Burma on October 16th. * * * * Another was 
taken by Theobald near Rangoon im a gravid condition in March.” 
By piecing all this evidence together, it would appear, therefore, 
that intercourse takes place at the end of the rainy season, about 
October, and that the young are born when the rains have again set 
in, about June or July. 
The single young one, referred to above, measured 180 mm. in 
length, and resembled the parent in every way except that, as is usually 
the case, the coloration and markings were more vivid. 
Herpeton tentaculatum. In the Catalogue of Snakes in the British 
Museum, the number of scales across mid-body in this snake is given 
as 37. An examination of a number of specimens has shown ine 
that this is not always the case, but that they may vary from 385 to 39. 
I have recently been able to examine a brood of 13 young ones, which 
shows this variation very fully. Unfortunately they did not come to
