region round the ear. An indistinct blackish line runs from 

 between the eyes on to the nape of the "neck, but owing to the 

 general dark colour this is very inconspicuous. Ears short, pro- 

 jecting but little beyond the fur, thinly hairy outside, nearly naked 

 in. Hairs of back dark smoky brown, their tips sometimes shining 

 coppery. Chin brown, like the face. Chest and belly either mixed 

 grey and white, with irregular pure white patches, or wholly pure 

 white, sharply defined from the upper surface, this colour also 

 occasionally passing round the proximal ends of the limbs in the 

 form of white rings, sharply contrasted with the general brown 

 colour. Whole of limbs otherwise like back. Tail tapering, the 

 hairs woolly to its tip, not straight terminally ; its colour uniform 

 smoky brown, with from one to three inches of its tip white. Naked 

 part below tip 5 or C inches in length, coarsely shagreened, sharply 

 defined from the hairy proximal part. 



Shull (PI. XIX. fig. 1) narrower and more elongated than that 

 of Ps. lemuroides. Nasals long, much vaulted above along the 

 middle line, their anterior points falling but little short of the level 

 of the tips of the premaxiUse, the nasal notch shallow, the nasals 

 only projecting about 2 or 3 millim. in front of their junction with 

 the ascending process of the premaxillae ; naso-maxillary and naso- 

 premaxiUary sutures about equal in length ; posterior edge of nasals 

 very convex backwards in the centre. Interorbital region narrow, 

 tapering evenly backwards, concave in the centre ; its edges more 

 or less inflated anteriorly, sharply ridged posteriorly. Anterior 

 palatine foramina reaching to about halfway between the canine 

 and p.' Posterior palate perfect, except that it has a few minute 

 openings, in no way comparable to the large vacuities present in 

 many species. BullsB slightly inflated. 



Teeth (PL XVIII. fig. 4). Upper i.* long, the amount by which it 

 exceeds i.^ nearly twice the vertical height of that tooth. I.^ and i.^ 

 small and delicate, about equal in section. Canine about as long as 

 i.^ rather longer than p.^ P.' about half the size of p.* in cross- 

 section. Molars rather small (see dimensions, p. 185). Lower i.' 

 simple, slender, spatulate. Intermediate teeth much reduced in 

 size, hardly visible.

=f I have to thank my friend Dr. B. CoHett, of the Christiania Museum, for 

 the loan of these specimens, and also for his permission to have casts made of 

 their skulls and of those of the two other Queensland species described by him.
