thinly clothed with black hairs, their inner sides naked ; tufts round 

 their bases behind white. Back mottled grey, darkest above the 

 forequarters ; the hairs brown at base, then, white, with brown 

 tips ; a few longer hairs black throughout. Chin black ; sides 

 of cheeks, throat, and chest glistening white ; rest of underside 

 dirty grey. Limbs dark outside, whitish in. 



Skull broad and flattened. Muzzle short, its sides compressed ; 

 infraorbital foramen triangular or oval. Nasals short, broad, 

 extremely expanded behind, their greatest breadth posteriorly equal 

 to or greater than their length, their posterior margin directly 

 transverse, except that the frontals generally project forwards in 

 the centre ; naso-premaxillary only about equal to, or even less 

 than, naso-maxillary suture. Frontal and interorbital region 

 broad, markedly flattened, or even concave in the centre. Post- 

 orbital processes prominent, strong, and triangular, the distance 

 between their tips exceeding the interorbital breadth by from 10 to 

 20 miUim. Temporal ridges but little developed, even in old age. 

 Anterior palatine foramina short, vaguely and irregularly defined 

 posteriorly; the palate round them raised so as to form a deep 

 concavity in which they are situated ; the raised edges of the 

 concavity continued backwards as sharp ridges. Posterior palatal 

 vacuities much as in the other species. Anterior wall of bullse 

 smaller and lower than in Ph. mitchelli. 



Eibs 13 in number, as in other Marsupials.

 anterior surface with numerous shallow vertical grooves. Lower
