ALLEN: MAMMALIA. 229 



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, d", 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,
