Distribution. — The whole desert region of Central Asia from 

 the north of Pekin to Yarkand ; also the country round the Cas- 

 pian sea. 



The above synonymy is copied from Buchner's account of 

 Przewalski's Mammals; Buchner believes that the curious semi-circu- 

 lar flap over the nose which was the character chiefly relied on 

 by Blanford in distinguishing the Yarkand species, G. cryptorhinus, 

 is purely artificial and can be easily produced by immersing the 

 fresh animal in alcohol (cf. Lataste Actes Soc. Linn. Bordeaux, 

 xxxix, p. 267, 1885) ; he therefore identifies G. cryptorhinus with 

 M. meridianus of Pallas.
