LIST OF THE SNAKES AT PRESENT KNOWN 

 TO INHABIT SIAM, 



Rv MALCOLM SMITH, m.r.c.s,, l.r.c.p. 



Since Captain Flower published his paper upon the Reptiles 

 of the Malay Peninsula and Siaui, {Proc. ZooL Soc. London, 1890, 

 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 to which he refers 

 are taken together instead of separately, and without going throuo-h 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 j'ears by the members of our Society, and I 

 therefore take this opportunity of publishing a new list, complete, as 

 far as possible, up to date. 



The recently issued volume upon the Reptiles and Ratrachians 

 of the Mala}' Peninsula, sets the northern limit of that region 

 .-it 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 boundar}', and have noted, with regard to all species added 

 since Flower's time, whether they w^ere obtained North or South of that 

 line. 



Flower's original paper contained 57 species from Siam. In 

 the present list the}' have no mark attached to them. 



Various expeditions to the Siamese Malay States, particular! \- 

 one by Messrs. Robinson and Aunandale to Patani in 1903 (FasdcuU 

 Mfdaifenses, Zooloyy, Vol. 1, 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 

 si)ecies up to 98. Those obtained North of the Isthmus of Kra are 

 marked with a *, those South of it with a §
