quite hiding the hairs growing between them. Their colour is pale 

 yellow basally, gradually darkening to orange on their middle por- 

 tion, and finally to black at their tips; some few, however, are 

 wholly yellow. The hair of the back is black or deep brown, 

 darker than in the Tasmanian variety ; this hair is, however, often 

 almost entirely absent, while, on the other hand, it occasionally 

 (perhaps seasonally) exceeds the spines in length on the middle of 

 the posterior back. Limbs and whole of underside clothed with 

 dark brown fur, thickly mixed with flattened bristles. Anterior 

 claws broad, stout, and straight, evenly increasing in length from 

 the sides to the centre of each foot. Palms quite naked, the skin 

 smooth, not granulated or striated, and without pads. On the hind 

 feet the hallux is provided with a short blunt nail, the second toe 

 has a very long and powerful curved claw twisted outwards and 

 backwards, and the third, fourth, and fifth have quite small and 

 feeble claws, disproportionaUy smaller than the second and appa- 

 rently of but little functional importance. The tail is about half 

 an inch long, conical, smoothly rounded, quite naked terminally. 



Skull -with a narrow flattened brain-case (capacity 22 to 27 c. cm.) 

 and a long slender rostrum, which is, as a rule, just about as long 

 as the brain-case *. Posterior basal region of the skull generally 

 without condyloid vacuities.
