crown, iiitorooular region, and sides of liead dark brown (apiiroachiiij; 

 seal-brown), slightly grizzled with pale grcj-ish and buffv ; chin and 

 throat almost uniform seal-brown. 



Individual variation (skins, B. Liu-kius) : — Not great, cliiefly 

 depending on the lesser or greater development of buffy tips to tlic 

 hairs of the back and rump, the more seal-brown or more mars- 

 brown tinge of the ground-colour of the fur, the amount of grizzling 

 on the head, and the richer or paler colour of the mautle. — In soino 

 specimens the buffy hair-tips ou back and rump are extremely short, 

 and almost ochraceous iu tinge, the general colour of the back and 

 rurap therefore seal-brown slightly varied with dull ochraceous. 

 In others, the buffy tips are so long as to almost completely cover 

 the dark base of the fur, making the back and rump approximately 

 pale buffy, with a narrow line of mars-brown along the lateral mem- 

 brane (9 ad., Ishigaki, June; 5.11.8.8). — Breast, belly, and flanks 

 varying from seal-brown tinged with vaudyck-brown to almost 

 uniform pale mars-brown. — ^ilantle varying from almost buff-yellow, 

 through pale ochraccous-buff, to pale butf ; side of foreucck always 

 much more whitish in tinge than mantle. The collar is never 

 complete below, always interrupted in the median line of the fore- 

 neck by a narrower or broader dark longitudinal stripe between 

 throat and breast ; iu one specimen ( 2 ^^-i Ishigaki, July; 5.11 .3.1)) 

 this dark area is so broad as to occupy almost the whole width of 

 the foreneck. Not infrequently the collar is partly interrnpted also 

 on the back of the neck, owing to the pale tips being too short to 

 completely cover the dark brown bases of the hairs ; in this case 

 the " collar " is confined to the sides of the mantle, and sides of the 

 neck and foreneck (compare Pi. fori)iosi(s). — Head varying, like 

 back, from seal-brown to mars-brown, never uniform, but the 

 amount of greyish and buffy admixture variable. 



The variations described above are independent of the sex of the 

 individuals. 



Young female, scarcely half-grown (Ishigaki ; 5. 11. 3. 10): Darker 

 and more uniform in colour than adults. Back, rump, breast, bellv, 

 and flanks dark vandyck-brown, approaching seal-brown. Head 

 blackish seal-brown. Mautle and sides of neck ochraeeous-butf.

History in literature. — In one of the earliest known lists of 

 Japanese mammals (Siebold, 1824) this species was recorded, under 

 the name Pt. rviri/^Uis Geoff., from Nagasaki (Kiushiu) and Je<ld<t 

 (Hondo). One year later (IB^.'i), on the atrcngth ol' a .single 

 specimen, acquired by the Leyden Museum from Blomhoff, " ancicn 

 resident ncerlandais au Japon," Temminck namcnl, described, and 

 figured it as Pt. dasymaUus (the specific name in allusion to the 

 dense woolly fur). Temminck copied Siebold's statement as to the
