coloured at their bases and tipped with brown. Chin, chest, sides, 

 and belly pure white. Limbs whoUy white throughout. Palms 

 (PI. XXI. flg. 9) hairy on their centres and fringed round their 

 edges, naked only along the undersides of the toes and on the pads, 

 of which there is one single weU-defined circular one at the bases 

 of each of the second, third, fourth, and fifth fingers, and another 

 below the middle phalanx of the second, third and fourth. Soles 

 (PL XXI. flg. 10) similarly hairy and fringed, only naked on the 

 compound terminal projection, on which there are two small round 

 pads, and on the underside of the fourth and fifth toes. Tail 

 about as long as the body without the head, wholly white, slender, 

 tapering, short-haired except along its terminal third above, where 

 a prominent white crest is formed, of which some of the hairs attain 

 to about one inch in length. 



Skull small and delicate, its general characters apparently very 

 similar to those of P. lagotis, except that the bullae are more evenly 

 hemispherical in their shape, and are not so prominently bulbous 

 postero-externaUy. 



Teeth much smaller than those of P. lagotis, but of quite similar 

 shapes and relative proportions. Molars small, quadrangular, with 

 low crowns and early-formed roots, their summits with numerous 

 sharp-pointed cusps as in Perameles, their general structure there- 

 fore much more distinctly insectivorous than in P. lagotis. Milk- 

 premolars, both above and below, much shorter than in P. lagotis, 

 their shape in section circular or triangular, and their size barely 

 half that of one of the lower third incisors.

Type in collection. 



This species, of which unfortunately the type is as yet the only 

 specimen known, presents an interesting approximation, in the 

 structure of its molars, to the genus Perameles, all its other cha- 

 racters, however, being quite those of Peragale. It is much to be 

 hoped that more, and especially adult, specimens of this handsome 

 animal may soon be obtained, and that its true locality may thus be 

 exactly determined.
