vVmONO some mammals collected in Yuiman by ]\Ir. George 

 i'one-t, and presented to the British Museum by Col. Ste- 

 phenson Ciiirke, C.B., there occur examples o£ two species of 

 Tamiops, both distinct from any as yet described. In working 

 these out, two other species of tlie genus, one also from 

 Yunnan and the other from S.E. Sian), prove to need 

 description. The first of Mr. Forrest's two S|)ecie3 is one of 

 tlie handsomest of the genus, as it combines the greater size 

 of T. swinhoei with the brightly contrasted coloration of some 

 of the smaller species. It nniy be called 



Tamiops clarkei, s]). n. 



Size large, practically as in T. sioinhoei, therefore con- 

 spicuously larger than in any of tiie other species, which are 

 all more or less subequal in this respect. Coloration brightly 

 contrasted, very different from the dull tones of swin/ioei. 

 Ground-colour of crown, nape, and fore-back pale huffy 

 olivaceous, paler than Kitlgwa>'.s "huffy olive." Median 

 dark stripe not commencing anterior to the lateral ones, all 

 three deep black, sharply defined. Inner light lines oliva- 

 ceous huffy, paler than the fore-back. Outer light lines 

 quite white, broad and conspicuous, ending anteriorly level 

 with the median dark stripe, not continuous with the sub- 

 oeidar light stripe. Outer black stripe fairly well developed. 

 Under surface white, not yellowish — in fact, whiter than in 

 any other species known to me; the hairs of the chin white 

 to their roofs, those of belly with slaty bases. Head with the 

 usual markings strongly develo[)ed, the main light subocular 

 stripe broad, white, and shown u[) l)y a darkening of the edge 

 of the ground-colour above it. Eyelids white. Ears not 

 heavily tufted, their edges white, their backs black, the hairs 

 behind the lips with white ends. Hands and feet greyish 

 buffy, becoming lighter terminally. Tail rather slender, tlie 

 hairs about I'd mm. in length, each buify at base, then black, 

 bmadly tipped with whitish. 



ISkuU nearly agreeing in size w^ith that of T. swinhoei. 



Dimensions of the tyjie (measured on the remade skin): — 



Head and body (c.) 154 ram. ; tail 112 ; hind foot 32. 



JSkuU : tip of nasal to front of interparietal 30 ; basilar
