MAMMALIA. 
By Guiover M. ALLEN. 
The splendid collection of mammals made by Mr. Zappey in the Provinces 
of Hupeh and Szechwan numbers some 375 well-prepared skins, together with 
a few trade skins and several large skulls and horns. The lack of comparable 
material has made the determination of some of the species rather difficult 
especially in the case of the genera Epimys and Apodemus, of which a number of 
closely allied forms inhabit southeastern Asia. Although Pére David collected 
with considerable thoroughness in parts of Szechwan, and later travellers have 
sent collections of mammals to Europe, there appear to be several species among 
the smaller rodents that have hitherto escaped notice. Of these, perhaps the 
most interesting are two very well-characterized species of voles belonging to 
the subgenus Eothenomys, and a very dark brown Craseomys, also apparently 
new, which is the most southeastern Asiatic species yet found, for voles seem 
to be few in southern China. 
All measurements are in millimeters and colors are according to Ridgway’s 
Nomenclature of colors.

BOVIDAE. 
Buporcas TIBETANUS (Milne Edwards). 
In the mountains at Lianghokow, western Szechwan, Mr. Zappey obtained 
a fine adult female and at Washan two young Takins. Milne Edwards (1868-74) 
who figured this animal and described its skeleton at some length, considered 
it a race of B. taxicolor of the Mishmi Hills. Lydekker in the London Field 
(1908, 111, p. 790) proposed the name Budorcas taxicolor mitchelli for a gray- 
colored female received by the British Museum from Szechwan, supposing it 
to represent a different race from the darker animal found in the same localities. 
Later, however, after comparison of specimens he (1908a, p. 795) reached the 
conclusion that the difference in color was merely sexual, and that B. taxicolor 
was specifically distinct from B. tibetanus of Szechwan. In a communication 
to the London Field, 19 March, 1910, 115, p. 520, he further records a gray 
male from Szechwan, apparently indicating that the two color phases are inde- 
pendent of sex. The adult female secured by Mr. Zappey represents the gray 
phase.
