Similasto the typical form in all essential characters, but differing 

 by its smaller size (c/. the skull dimensions, p. 185), and especially 

 by the much feebler development of the upper canine, which ia 

 barely one half as long as \}, and of p.', which is quite minute and 

 sometimes absent. The upper i.'' and i.' are also proportionally 

 smaller and weaker (see PL XVIII, fig. 3). 



Hab. Central Queensland. 



Co-types in the Christiania Museum and in collection. 



This smaller form of P. volans was discovered by Dr. Lumholtz

 with extra tragoid projections in addition to the metatragus (see 

 PI. XVII. fig. 4). Planks without a flying-membrane. Fore toes 

 subequal, the first two very markedly opposable to the outer three 

 (see PI. XVII. fig. 6), their relative lengths in the following 

 order — 4, 3, 5, 2, 1. Claws medium. Palms and soles naked, 

 with large rounded and striated pads; underside of heel hairy. 

 Tail long, tapering, its distal third generally comparatively short- 

 haired ; its tip naked underneath for a distance varying from 4 to 

 150 millim,, generally about 100 millim. ; the whole of the under- 

 side shorter-haired than the upper ; markedly prehensile (see 

 PI. XVn. figs. 7, 8). MammsB 4 f. No chest- or crown-glands, 



* Said to be founded on Trichoeums vulpecula, but obTiously a misspelt form
