Type locality, Tenasserim. Types in the British Museum. 



Distribution. From the type locality southwards through 

 Peninsular Siam to the Malay Peninsula. Undoubted records of this 

 frog appear to be only from Tenasserim, from King and Elphinstone 

 Islands (Mergui Archipelago), from Patiyu (P. Siam) and from the 

 Andamans. Recently I have examined a specimen obtained at 

 Kuala Teku, Gunong Tahan, Malay Peninsula, by the F. M. S. 

 Museums collectors. The Robinson and Kloss expedition to Penin- 

 sular Siam in 1919, found this frog fairly common at Victoria Point 

 (S. Tenasserim), and at Mamoh, Tapli, and Tung Pran, and a good 

 series was obtained from these localities. Anderson records it as 

 common on .King and Elphinstone Islands. 



Colouration. All the examples I have examined from Tenas- 

 serim and Siam are of the same colour, the predominating hue being 

 olive brown with lighter and darker markings. The Gunong Tahan 

 specimen is of a reddish-brown above, with small black markings ; 

 throat and chest handsomely marbled with brown. 



Remarks. The tibio-tarsal articulation in some of my speci- 

 mens from Peninsular Siam reaches the tip of the snout or beyond. 



I have examined two examples from the Andamans kindly 

 sent me by Dr. Annandale (Indian Mus. Nos. 9381, 10436), and they 

 differ from my specimens in the following particulars : — the more 

 anterior position of the vomerine teeth, from the extreme anterior 

 inner borders of the choanae, the more emarginate web to the toes, 

 the shorter, more rounded, inner metatarsal tubercle, and in the 

 presence of a small, but distinct, outer metatarsal tubercle.
