Pig-footed Bandicoot. 



Size small, form delicate. Fur coarse and straight, but not in 

 the least spiny, very much as in Perameles hougainvillei. Underfur 

 abundant, slaty grey at base, dull yellow at tip. General colour of 

 head and body uniform coarsely grizzled grey, with a tinge of fawn. 

 Ears long and narrow, their outer margin slightly concave just 

 beneath the tip ; thinly haired; their backs dull chestnut-brown, 

 darkening towards the tip. Metatragus short and broad. Longer 

 hairs of head and back brown-tipped, underfur yeUow-tipped, the 

 latter more orange in Western Australian specimens. Chin, chest, 

 and beUy white, the line of demarcation on the sides not sharply 

 marked. Limbs long and slender, short-haired, pale grey or white, 

 with a yellowish tinge. Palms whoUy hairy, except on the terminal 

 pads of the two functional digits ; these latter with long slender 

 claws ; the rudimentary fourth toe entirely clawless, reaching only 

 to the middle of the metacarpus of the third. Hind feet very long 

 and thin, hairy except' just below the heel, on the small circular pad 

 at the base of the fourth toe, along the underside of that toe, and 

 on its very large terminal pad ; united second and third toes only 

 reaching to the base of the fourth, and the fifth toe again falling 

 just short of their base. Tail about half as long as the body, grey 

 below and on the sides, black above, where there is a short and 

 inconspicuous crest. 



Shutl as described above. Nasals with their posterior (maxillary) 

 half evenly broader than their anterior (premaxillary), but not 

 markedly expanded at their extreme back. Forehead peculiarly 

 broad and flat; supraorbital edges square; lacrymals strongly 

 ridged. Anterior palatine foramen reaching just to the front of the 

 canine. A pair of irregular reticulated vacuities reaching from p.' 

 to p.^ and a second pair, often united in the centre, opposite the 

 molars. Extreme back of palate also with vacuities. Openiag of 

 foramen magnum partially closed in below. 



Teeth. Upper i.* about half the size of i.*, pointed, touching the
