APPENDIX II. 
MAMMALS COLLECTED IN SHANSI, SHENSI AND KANSU 
—BY A. DE C. SOWERBY. 
HE Mammals collected during the expedition, and presented by Mr. Clark 
to the United States National Museum, number 220 specimens. Follow- 
ing are details of the 33 species represented, besides the number, sex and 
locality of each specimen. 
A series of these, representing all the species taken, was brought to 
London in the summer of tgto by Mr. Gerrit S. Miller, in whose company I 
compared them with the Chinese material in the British Museum. Complete 
facilities for this work were courteously granted by Mr. Oldfield Thomas, 
F.R.S., Curator of Mammals at South Kensington. The new forms which 
the collection contained have already been described by Mr. Miller in two 
papers issued August, gto and February, 1911. The first of these is entitled 
‘* A New Carnivore from China” (from the proceedings of the United States 
National Museum, vol. xxxviil., pages 385-386), and it deals with the new 
species Vormela negans from the Ordos Desert. The second paper is 
entitled ‘Four New Chinese Mammals” (from the Proceedings of the 
Biological Society, Washington, vol. xxiv., pages 53-55). This deals with the 
four new species and sub-species Epftesicus serotinus pallens, Microtus pullus, 
Allactaga mongolica longioy, and Ochotona annectens, from Shansi and Kansu. 
The descriptions are embodied in this report. 
The determinations and names of the other species dealt with in this 
paper have been kindly verified and revised for me by Mr. Miller. The new 
species or subspecies are underlined.
