The covering of the tail is reddish grey, and only towards the 

 tip do the hairs on the upper side become black, but on account of 

 the very thin covering of hair, this colour is not very perceptible ; the 

 tip itself also is black underneath. 



The skull. Compared with Phascologale flavipes, the skull is 

 more strongly built, although the teeth are weaker. The crests and 

 processes, which in Pk flavipes were faint or entirely wanting, are 

 here distinct; the skull is narrower, but higher, and the zygomatie 

 arch longer. 



Compared with Ph. apicalis Gray, this latter species has larger 

 auditory bullae, but shorter foramina incisiva; p ^ \s almost rudimen- 

 tary, and p ^ larger than both the other premolars together. Further- 

 more in Ph. apicalis (as in Ph. flavipes) the sagittal crest and 

 postorbital processes are wanting. Likewise in Ph. apicalis the ears 

 and the tail are shorter, and the feet larger than in Ph. virginiae. 

 Some measurements of the skull: 



Length of skull 31,5 mm 



Breadth across zygomatie arches 19 „ 



Heigth of skull above the end of bulla .... 11 „ 

 Interorbital space (least width between orbitae) . 5,5 „ 



Breadth of skull across ear-openings 12 „ 



Length of zygoma to front margin of orbita . . 17 „ 



Length of dental series in upper jaw 15 „ 



Length of dental series in lower jaw 13 „ 



The nasalia are narrow, almost imperceptibly broader behind, than 

 in front; the suture, with the frontalia, form together a sligthly 

 rounded angle. Their front edges extend immediately over the space 

 between i'^' and i^. The frontalia are comparatively narrow, with 

 distinct processus postorbitales. The sutura coronalis forms a com- 

 pletely straight line in the middle, but downwards, in the orbital 

 margin, a prominent rounded arch, the centre of which points straight 

 towards the postorbital process. Interorbital space very narrow. 



The parietalia form a strong sagittal crest, which proceeds from 

 the postorbital processes, but already meet in front of the sutura co- 

 ronalis, and joins behind with the equally high occipital crests. In 

 their shape the parietalia are strongly arched and high, but compa- 

 ratively narrow at the sides; the width of the skull, measured across 

 the openings of the ear, is not greater than its height from the bulla 

 to the upper margin of the sagittal crest.
