564 Mr. P. S. Kersliaw on new 



revoili and deserli, but lacking the pinkish tone of those 

 species. There is none of the red tint of rufescens and 

 pidcher, which are its nearest nortlierly neighbours. Paler 

 on the sides. The transition to the white of the under 

 surface is less abrupt than in rufescens and its allies. Wliite 

 markings round tlie eye very large and conspicuous, and 

 interrupted posteriorly by a streak of " inunimy-brown.'" 

 The white colour above the eye measures horizontally 23 mm., 

 and vertically at the widest part beiiind the eye 4*7 mm. 

 There is a white tuft at the base of the ear and a cinnamon 

 patch behind it. Under surface in the type white, with 

 slaty bases to the hairs except in an area between the thighs 

 about 25 mm. longitudinally, where the bases of the hairs 

 are white. This slaty colour is a variable character, strongly 

 njarked in some specimens and almost wanting in others, 

 while in one (out of thirteen specimens examined) the hairs 

 are white to their bases on the whole of the under surface. 

 In all cases the hairs in the area mentioned between the 

 thighs are white to their bases. There is a small white 

 patch of hairs visible from above on each side of the tail. 

 Below the tail a large triangular naked patch, the apex pointing 

 downw^ards, larger in the females than in the males. In the 

 type this patch measures from root of tail to apex of triangle 

 18 ram., and about 14 mm. across at its broadest part. Tail 

 clothed with brown hairs above and white hairs below. Of 

 the specimens examined, nine have the tail shorter tiiun the 

 head and body, three have it longer, and in one specimen the 

 lengths are equal. The difference, in any case, is never 

 great — little more than 10 mm. Feet in the type white, with 

 a suspicion of buff. This buffy tint is stronger in certain 

 specimens. 



Skull and teeth as in rufescens.
