In the lower jaw, fuiictional teeth, as previously mentioiied, are 

 wanting betvveen the incisor and ^ 3 , The cauine in one or two of 

 the specimens is present, like a minute globule on the margin of one 

 or both jaws, and in some p 1 and p 2 likewise appear as mere grains, 

 whilst there exist no trace of these whatever in others. 



The dentition, when complete (which it is not in any of the pre- 

 sent specimens) will therefore be:

This species is not uncommon in Queensland, but, like Fhal. vul- 

 pecula, it Visits the low-lands only in winter, and disappears entirely 

 in summer. Several individuals are sometimes found living in the 

 same hole of a tree; thus, on one occasion, when a large gum-tree 

 was cut down in May 1882 at Mackay, Dr. L. obtained several spe- 

 cimens. 



The colouring is typical in all the specimens of the collection. 

 In C , a male , the lower surface of the patagium is greyish black 

 whilst in the other specimens it is whitish. 



The young, the length of which is about 130mm (head inclu- 

 ded), and the tail 150 mm, has the upper surface of the body covered 

 with Short hairs, whilst the under surface as well as the flank mem- 

 brane (on both surfaces) is still almost quite naked, notwithstanding 

 that the animal is as large as a medium sized rat ; only on the throat 

 and ehest there are short and fine hairs to be found. The tail is 

 clothed to the end with rather short, adpressed, greyish black hairs; 

 the outer half is quite black.
