Petauristd nitida niarchio, subsp. ii. 



Colour comparatively dark, a number of the dorsal hairs 

 with black ends, which overlie and partly hide the deep 

 rutbus chestnut of the fur in general. Ears themselves not 

 unlike those of melanotus, though the dark hairs of the 

 metectote are blacker and more prominent ; but in addition 

 the long hairs of the side of the head behind the ears are 

 also black-tipped so as to form a darker area in this region. 

 Hands with the chestnut penetrating on to the metacarpals 

 nearly to the base o£ the digits. 



Condylo-basal length of skull 67'2 mm. j upper tooth- 

 row, exclusive of p*, 15'5.

Ground-colour almost as light as in melanotus, but darkened 

 by blackish tips to the dorsal hairs, so that the general colour 

 is intermediate between that of melanotus and marchio. 

 Head like body. Dark orbital rings at a maximum. Ears 

 apparently shorter than in the other forms and less narrow; 

 their backs heavily tufted with deep black hairs, which form 

 a conspicuous black patch on each side. Hands and feet 

 wholly dark, the rufous not trespassing on to the metapodials.
