In the shortness of the fur and the naked soles to the feet 
this form, described by Westerman from a specimen taken at 
Padang, Sumatra, resembles the preceding. 
The general colour throughout, with the exception of the 
chin, throat, fore chest, and a patch on the vent, is dark 
brown, darkest on the tail and feet and lightest on the nape 
and shoulders, the underparts not being in any way lighter 
than the back. ‘The lines on either side behind the ear 
noticed in the last form are similar in this race and well 
marked. The chin is white, the throat and fore chest pale 
yellow, and the vent-patch dull white. 
The skull differs only in being slightly smaller than in all 
the preceding forms. 
Dimensions (from skin):—Head and body 450 millim.; 
tail 450. 
Skull: greatest length 92; basal length 8L; zygomatic 
breadth 53; length of palate 41; least breadth at postorbital 
constriction 21; least breadth of palate between carnassials 15. 
Hab. Sumatra, Java, Borneo.’ 
This race is most nearly allied, as might be expected, to the 
Malay form, but is very much darker in colour, which renders 
it easily distinguishable. 
Mustela flavigula wanthospila (Swinhoe). 
Martes flavigula, var, vanthospila, Swinhoe, P. Z. 8. 1870, p. 623. 
I have examined the Formosan form of JL flavigula 
described by Swinhoe, of which the type is the only specimen ; 
it is, as one would expect, an intermediate link between the 
two southern forms on the one hand, and the Chinese form, 
which I propose to describe next, on the other. In size it is 
much the same as Bornean examples—that is to say, small— 
although Swinhoe’s measurements, quoted below, make it as 
large as my measurements of the Nepal form. ‘Lhese latter, 
however, being made from the dried skin cannot be considered 
accurate, and the measurements of the skulls, always a much 
safer test, show it to be rather smaller. 
The hair on the body is of moderate length, although not 
so long as in the mainland race, and the soles of the feet 
hairy. The crown of the head, sides of the face, and nape 
are light brown (bistre, Ridg.), the hairs on the nape having 
white tips; the dark stripes extending backwards from the
