I. — Note on Three Species of Batrachia from Jfottlmein, — by 

 Dr. F. Stoliczka. 



[Received and read 7th Sept., 1870.] 



The two known species of Oxyglossus, and one new of Ixalus, have 

 been lately obtained, in the same locality, by Mr. W. Theobald on 

 the Ataran river, east of Moulniein (Tenasserim Province). Both 

 genera characterize the Malay fauna. The discovery of the Oxyglossi 

 is particularly interesting in point of geographical distribution. 



0. Icevis has up to this only been recorded from the Philippines 

 and is stated by Giinther to be : ' confined" to these islands. 



0. lima occurs in Java, China, Camboja and Siam, and is said 

 to have also been found in Bengal. The last locality was consi- 

 dered doubtful, but, through the discovery of the species at Moul- 

 mein, it receives more probability, though specimens in our neigh- 

 bourhood must be of extreme rarity. They are not represented in 

 any of our collections, while 0. Icevis is. 



The discovery of the Oxyglossi so far north is further interesting 

 in connection with the fossil species, 0. pusillus, which I have 

 described from the upper tertiary frog-beds of Bombay, (vide 

 Mem. Geol. Survey of India, vol. vi, part III, p. 387). And, 

 since I had the opportunity of examining the two recent species, 

 I am confident that the generic determination of the fossil one is 

 correct. This fact, though as yet almost single, clearly indicates 

 that the Malabar coast had its Malayan fauna, — which is so consi- 

 derably different from that of Central India, — already at an earlier 

 period than the present one. It remains to be shewn, how far this 

 observation will be supported by the study of the fauna of the up- 

 per tertiary deposits of the Indian Peninsula. Good materials for 

 this are, however, as yet a desideratum. Every fragment of a bone 

 and every shell must be collected and carefully examined, before 

 we can speak with any confidence on this important subject. 



The genus Tcoalus includes a number of small tree-frogs without 

 vomerine teeth. The species chiefly occur in Ceylon, South India 

 (Nilgheris) and the islands of the Philippine and Indo-Malayan 

 Archipelago, but none have as yet been reported as far North as 

 Moulniein.
