CHAPTER VIII 
BIOLOGICAL WORK 
HE 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
