^()Q Mr. O. Thomas on 



lltli September, 1904, and presented by Mr. A. B. Bayley- 

 Worthington. Seven specimens. 



Fifteen. 

 Twelve. 

 Two. 



6. Sorex mi?iiitus, L. 



7. Crocidura tlensis, Mill. 



8. Felis caudata, Gray. 



y. Patorius eversmanni, Less. 



Male. 



The British Museum series of Asiatic polecats shows these 

 animals to be by no means so unvarying in colour as might 

 be supposed from Mr. Hollister's statement as to their con- 

 stancy. In two cases sets from the same place differ con- 

 siderably inter se, as, for instance, in the brown or white 

 colour of the crown, and there is, of course, always a wide 

 difference between winter and summer specimens. 



10. Mustela erminea ferghance, Thos. 



Three males, in winter pelage. 



In addition to these three specimens I liave before me a 

 female in winter pelage from Przewalsk (Coll. Kutsenko) and 

 the type, in summer pelage, from Mt. Kara-Karyk, Ferghana 

 (Coll. Barey). The last was said by its collector to be a 

 male, a statement I published when describing the subspecies ; 

 but while the skin shows no external evidence of sex, its 

 agreement in size and skull- characters with Mr. Kutsenko's 

 female is so close that I am now disposed to think that it also 

 is a female. 



This mistake, to which I regret that I gave currency, may 

 result in the invalidation of Mr. Hollister's '"''Mustela Itjmani,^^ 

 described on a male so much larger than the Ferghana speci- 

 men that Mr. HoUister appeared to be quite justified in 

 distinguishing it, on the assumption that the sexes were the 

 same. Further summer skins of both forms will, however, 

 be needed before this question can be definitely settled. 



11. Mustela sacana. sp. n. 



c? & ? . Przewalsk. 



Proportions and general appearance as in M. altaica, Pall. 

 {M. alpina, Gebl.), the body of a similar buffy colour above,
