CHAPTER VIII 

 BIOLOGICAL WORK 



THE biological work done on the journey made 

 by Mr. Anderson and myself through Shensi, 

 along the Ordos border and back into Shansi, 

 resulted in some very interesting discoveries. No 

 fewer than eight new species and five new sub- 

 species were described by Mr. Oldfield Thomas 

 of the British Museum from our collection of 

 mammals. The descriptions of these, together 

 with the names of and notes on the other twenty 

 species represented, were published in the Pro- 

 ceedings of the Zoological Society of London^ 

 1908, pages 963 to 983. A detailed list would 

 therefore be superfluous here, though the following 

 general remarks may be of interest to the reader. 

 As Mr. Thomas pointed out, the most striking 

 feature of the mammalia of the districts adjoining 

 the Ordos is a general paling of colour, as compared 

 with the nearly related species of the non-desert 

 regions further south and east. This is especially 

 noticeable in the Ordos chipmunk (Eutamias
