Mammals collected in Turkestan. 2G1 



July, 1889. Eeceived in exchange from the St. Petersburg 

 JVJuseuni. 



The small red-bellied marmot of the Tian-shan was iden- 

 tified by Dr. Biichner as A. dichroas, Anderson; but a 

 cotype of tliis latter in the British Museum shows that it is 

 a wholly different animal, of a more or less chocolate-brown 

 colour. Dr. Biichner has so fully described the present 

 species and stated its relationship to the other Siberian forms 

 that further detail is not now required. 



It may be noted that A. baibacinusj Brandt, is absolutely 

 a nomen nudum, whether Dr. Biichner was or was not right 

 in separating the present animal from it. 



9. Rhomhomys opimus^ Licht. 



c? . 34, 54, 61 J ? . 56, 57, 59, 62, 88, 93. 50 miles S. W. 

 of Bukhara. 600'. 



10. Meriones tamariciaus^ Pall. 



S. 5, 98, 99 ; ? . 4, 95. Samarkand. 2000'. 



11. Meriones eversmanm, Bogd. 



(J. 23, 67, 84, 85; ?. 7, 68, 71. 10-20 miles S. of 

 Samarkand. 2000'. 



" In small colonies on semi-cultivated desert.'''' 



I provisionally use the name eversmanni for this gerbil as 

 being undoubtedly applicable to it, but it is so closely related 

 to the Kandahar Al. erythrourus, Gray, that its ultimate 

 union with that species is very probable. 



Gerbils of the same type are widely distributed over 

 S.W. Asia, examples from Karyatein (Kargeten), near 

 Damascus, being quite similar to typical Afghan specimens. 

 SundevalFs M. crassus from Sinai also belongs here. 



A smaller species, M. longifrons, Lat., occurs in S.W. 

 Persia (Ahwaz, Busrah, &c.) and Arabia (Jedda). 



12. Meriones meridianus, Pall. 



6 . 43, 44, 45, 46, 51, 52 ; ? . 48, 49, 50. 50 miles S.W. 

 of Bokhara. 600'. 



Biichner has placed Blanford's cryptorhiiins as a synonym 

 of meridianus, but specimens of it in the British Museum 

 indicate that, while undoubtedly closely allied, it may be 

 distinguished by its larger size.
