as a new species, although it may eventually be found that intergradation takes 
place between these eastern and the typical western representatives of the high 
altitudes. Possibly also Styan’s remarks apply in part to the undescribed’ 
species. 
DREMOMYS SENEX, sp. nov. 
Type:— Skin and skull, No. 7582 M. C. Z., female adult, from Nantow, 
Ichanghsien, Hupeh, China. February 5, 1909, Walter R. Zappey. 
General Characters:— Nearest to D. pernyi, from which it differs in its 
greater size, with notably longer tail and larger skull, in having the postauricular 
patch white instead of deep ochraceous buff, and the median area of the ventral 
surface of the tail nearly uniform clay color instead of whitish. 
Color:— Forehead, top of head, neck, outer surface and anterior margin 
of ears, dorsum, and external surfaces of fore and hind feet a uniform grizzled 
olivaceous, the separate hairs with a plumbeous base, succeeded by one or often 
two narrow rings of buff which are separated by a slightly longer black ring. 
The tips of the hairs are black and in the dorsal region there are a few scattered 
hairs entirely black. Sides of the muzzle nearly clear gray; a poorly defined 
eye ring of buff; cheeks washed with buff. Postauricular spots clear white. 
Ventral surface of body from chin to anus and the inner surface of the limbs, 
white washed with buff, especially on the outer edge of the thighs. The white 
hairs of the chin and throat are very slightly gray at their bases, but those of 
the rest of the under parts have the bases dark slate color. Anal region, posterior 
edge of thighs and base of tail below, light orange rufous. Tail above mixed 
black, pale buff, and white, the separate hairs ringed at the base with very pale 
buff, then black, then buff, followed by a longer black ring and a grayish white 
tip, that forms a bordering fringe. Ventrally the color is similar except that the 
hairs of the central area of the tail are buff or clay color, slightly grizzled by the 
black rings, and quite without the long white hairs that in D. pernyi predominate 
in this area. 
Skull:— The skull is similar to that of D. pernyi but slightly larger as shown 
by the measurements below. 
Measurements:— The collector’s measurements of the type are:— total 
length, 373; tail, 171; hind foot, 54. A second specimen from Ichanghsien, 
No. 7583, <o’, measured:— total length, 375; tail, 176; hind foot, 52. The 
skull of the type shows the following dimensions (the figures in parentheses are 
those of a large specimen of D. pernyi):— greatest length, 53 (51); basal length,
