Colour. — Three colour phases are represented in the small series 

 examined, viz. : — 



(1) Back light grey ; head, mantle, and underparts some shade 

 of chestnut or hazel or ochraccous ; flanks thinly or heavily mixed 

 with greyish (two skins : J ad., type, teeth well worn, P. Pandak, 

 Sept., 95.11.8.3 ; $ ad., teeth somewhat worn, I'. Panjang, July, 

 95.11.8.2). — General colour of back pale mouse-grey, gradualh' 

 lightening on hinder back and rump to silvery whitish-grey. 

 Individual hairs silvery wiiite and blackish; on tlie anterior half 

 of the back the blackish and whitish hairs are nearly equal in 

 number, thus producing the general effect of a pale mouse-grey ; 

 further back the blackish hairs gradually become scarcer, until on 

 the rump the silvery whitish colour is largely predomijiant. All 

 hairs with a distinct silky gloss. In one specimen the colour of the 

 back and rump is almost imperceptibly, in the other (type) distinctly 

 washed with buff'y especially on rump and along edges of membranes. 

 — Centre of breast and belly ricli golden ochraceous or orange-buff, 

 gradually darkening on sides of breast and bellj- through hazel into 

 chestnut ; flanks in one specimen (typ<i) seal-brown thinly sprinkled 

 with greyish, in the other pale mouse-grey like back.- — ]Uant]e 

 hazel j)artly clouded with chestnut (type), or chestnut -with 

 ochraceous-buff'y hair-bases (the other), jjassiiig through a darker 

 shade on sides of neck into deep chestnut or chocolate on foreneck.- — 

 Crown nearly ochraccous-buff' in centre, darkening through tawny 

 ochraccous or deep mars-brown on sides of head into chestnut or 

 liglit seal-brown on throat.
