44 INTRODUCTION, 



122. Ilapalotis arboricola, MacLeay. 



This is another of the Austrahun mammals of which I 

 have not had an opportunity of examining specimens. 



Two coloured sketches^ accompanied by the following notes, 

 were kindly transmitted to me by Mr. Gerard Krefft: — 



" The only example of this rarity which has yet been 

 obtained has been presented to the Australian Museum by 

 W. S. MacLeay, Esq. It was caught at Elizabeth Bay, 

 where it inhabits the lofty Eucali/ptij and builds a nest among 

 the branches, with leaves and twigs, like that of a bird." 



*' Fur rather harsh to the touch, and of a slate-grey next 

 the skin, — the longer hairs, or outer coat, being mingled 

 ochreous and black ; sides greyish, with an admixture of 

 ochreous yellow, which becomes darker towjirds the back, 

 and has the black hairs much longer than on any other part; 

 outer surface of the cars clothed with very short white hairs; 

 throat and abdomen white ; tail thinly clothed with dark- 

 brown hairs ; toes of the hind and fore feet covered with 

 short white hairs."
