XLYITI. — On some Batrachians and Reptiles from Tibet. 

 By G. A. BouLENGEK, F.K.S. 



The fishes obtained by Lieut.-Col. L. A. Waddell, C.B., and 

 Capt. H. T. Walton, of the Tibet Frontier Commission, have 

 already been described by my colleague Mr. Regan. I now 

 beg to offer a list of the batrachians and reptiles collected by 

 these gentlemen and preserved in the Natural History 

 Museum. 



Batrachians. 



1. Rana Pleskei, Gthr. 



Nanorana Tleskei, Giinth. Anmiaire Mus. Zool. St. P^tersb. 1896, 

 p. 199; Bedriaga, Przewalski Eeis., Zool. iii. i. p. 32, pi. i. fig. 6 

 (1898). 



^Numerous specimens were collected by both Lieut.-Col. 

 Waddell and Capt. Walton up to an altitude of 15,000 feet. 

 So far only one species of batrachian — Bufo viridis, Laur. — 

 was known to occur at such an altitude. The few examples 

 previously described by Giinther and by Bediiaga were 

 obtained in the Province 8ze-Chuen and in North-eastern 

 Tibet. 



Two small groups of vomerine teeth are sometimes present 

 behind the level of the choanas, the outer metatarsals are more 

 or less separated by web, at least distally, and a true web 

 does not exist between the fingers. I am therefore unable to 

 accept the genus Nanorana. 



Rana PIcshei is very closel}' allied to R. Blanfordii, Blgr., 

 the habitat of which is unknown. 



Reptiles. 

 1. Alsophylax tibctanus, sp. n. 



Head rather strongly depressed, one and one third as long 

 as bread ; snout obtusely jwinted, slightly longer than the 

 diameter of the orbit or the distance between the eye and the 

 car-opening; latter moderately large, oval, oblique. Body
