LIST OF THE SNAKES AT PRESENT KNOWN 
TO INHABIT SIAM. 
By MALCOLM SMITH, m.r.c.s., u.R.c.P. 
Since Captain Flower published his paper upon the Reptiles: 
of the Malay Peninsula and Siam, (Proc. Zool. Sec. London, 1899, 
pp. 600—696) no work of any kind has appeared dealing with the 
snakes of this country. His paper, moreover, as far as Siam is con- 
cerned, is obscured by the fact that the two regions te which he refers 
are taken together instead of separately, and without going through it 
in detail it is impossible to see what actually belongs to each country. 
A great many species have been added since that time, partic- 
ularly in the last two years by the members of our Society, and | 
therefore take this opportunity of publishing a new list, complete, as 
far as possible, up to date. 
The recently issued volume upon the Reptilesand Batrachians 
of the Malay Peninsula, sets the northern limit of that region 
at the Isthmus of Kra, thus including a portion of Siam. A certain 
amount of overlapping in the lists of the species of the two countries 
is therefore inevitable, and in order to avoid confusion I have adhered 
to that boundary, and have noted, with regard to all species added 
since Flower’s time, whether they were obtained North or South of that 
line. 
Flower’s original paper contained 57 species from Siam. In 
the present list they have no mark attached to them. 
Various expeditions to the Siamese Malay States, particularly 
one by Messrs. Robinson and Annandale to Patani in 1903 (Fuaseteuli 
Malayenses, Zoology, Vol. |, pp. 131-176), have added another 16 to 
that number. These are marked with a f 
25 more may now be included, bringing the total number of 
species up to. 98. Those obtained North of the Isthmus of Kra are 
marked with a *, those South of it witha §
