ON REPTILES AND BATRACHIANS FROM 



THE COAST AND ISLANDS OF 



SOUTH-EAST SIAM. 



By Malcolm Smith, m.k.c.s., LK.c.r., and C. Bodens Kloss, f.z.s. 



[During December .and January, 1914-5, I spent six weeks on 

 the east side of the (iulf collecting vertebrates of all kinds. I was 

 accompanied by three Dyak assistants and, at my suggestion. Dr. 

 Smith sent his reptile-collector witii m}' party. 



On Koh ' Chang and Koh Kut, at each of which we spent 

 over a week, we obtained a fair number of reptiles, but on several of 

 the smaller islands between these, on which we passed only a night or 

 two, we were entirely' unsuccessful. We had of course better fortune 

 on the mainland, between Ok Yam at the southern extremity of the 

 Franco-Siamese boundar}', and Lem Ngop opposite Koh Chang, partly 

 because at all the places where we camped there were villages where, 

 encouraged b}^ small presents, the inhabitants brought us such speci- 

 mens of reptiles and batrachians as were easily found in the vicinity, 

 and partly because the fauna was naturally much richer. 



There is but little to remark about man}'' of the species ob- 

 tained, but an endeavour has been made to give as full a set of local 

 references as the literature available will permit; until lately no serious 

 study of the leptiles of Siam, as a zoo-geographical district, has been 

 undertaken, and so it has remained for a beginning to be made in the 

 compilation of a synonomy. The well known works of Mr. Boulenger, 

 namely, the British Museum Cataloijaes and the Faunas of India and 

 the Malai/ Peninsula with the synotiomy in those volumes have not 

 been quoted, but all other references of any value that we have been 

 able to gather, have been inserted. The collection consisted of about 

 250 specimens, and we have given the first set to the British Museum 

 of Natural History ; to Mr. G. A. Boulenger, of that institution, we are 

 much indebted for putting us right on two or three points of identifi- 

 cation, and confirming the correctness of the whole.
