Lessee FLTiNa Phalangbk. 



Size small. Fur soft and silky, not so long as in P. sciureus. 

 Colours almost precisely as in that species, the ground-colour being 

 of the same soft pale grey, and the dark markings situated on the 

 same parts of the body ; the dorsal stripe, however, is often more or 

 less indistinct, the hairs of the underside are nearly always grey 

 basally (at least in the continental variety), and the extreme tip of 

 the tail is very frequently white. Ears (PI. XV. fig. 9) large, 

 evenly oval, laid forward (in spirit-specimens) they reach to about 

 halfway between the eye and the tip of the nose. Length of fore 

 toes in the following relative order of length — 4, 5, 3, 2, 1. Under- 

 side of heel hairy, except a round spot on its tip, which, is therefore 

 separated from the main part of the naked sole by a narrow hairy 

 band. Tail markedly more bushy basally than terminally, the 

 hairs attaining a length of from 20 to 30 millim. along its proximal 

 inch. 



SJtm.ll (PI. XVI, fig. 9) as in F. sciureus, but with a shorter and 

 more sharply pointed muzzle, and of course very considerably 

 smaller. Supraorbital edges more or less parallel, distinctly beaded. 



* u,. Ears oomparatiyely large. Colour grey. Bailee 

 large, projecting downwards anteriorly. 



Australian Var. typicus. 



b. Ears small. Colour more yellowish. Bullae 



small. Papuan Ya.r. papuanus, -p. 158.
