A SMALL COLLECTION OF REPTILES AND BATRACHIANS 

 FROM EASTERN MONGOLIA. 



BY WITMER STONE. 



Through the generosity of Messrs. J. Edward aud George Far- 

 num, aud of Dr. A. Donaldson Smith, the Academy has received a 

 small collection of Reptiles and Batrachians collected by them on 

 a,n expedition through eastern Mongolia, undertaken in May-July, 

 1897. 



Although none of the species represented are new to science, a 

 list of them will prove of value as adding to our knowledge of their 

 geographic distribution. 



BATRACHIA. 

 Rana dybowskii Gtinth. 



Three specimens taken east of the Kiu-ghan mountains. Bou- 

 lenger regards this Asiatic form as identical Avith the R. temporaria 

 of Europe. It is probable, however, that it represents at least a 

 geographic race. 

 Rana chinensis Osbeck. 



One specimen from Khiu-ghan mountains, aud two from 

 Lama-mio. 



This frog is clearly distinct from R. esculenta. Boulenger 

 regarded it as a subspecies in his Catalogue of the Batrachia Sali- 

 ■eniia aud named it japonica. R. marmorata of Hallowell has clear 

 priority over this name and, according to Boulenger (Tailless 

 Batrachia of Europe), R. chinensis Osbeck is based upon the same 

 animal and is prior to either. 

 Bufo japonicus Schleg. 



Two specimens from the Tore river. 



I follow the British Museum Catalogue in regarding the Asiatic 

 and Japanese animals as identical. Should they prove recognizable 

 races, the above name will apply to the island form. 

 Bufo raddei Strauch. 



One specimen from a lake near Lama-mio and seven others 

 from various localities in eastern Mongolia.
