220 DR. J. E. GRAY ON AUSTRALIAN MAMMALS. [May 8, 



stralia, which are interesting as containing some species which have 

 not hef'ore heen recorded as natives of Australia. 



HlPPOSIDEROS ALBANENSIS. 



Black brown ; hair white, with minute black tips ; beneath greyish 

 black, hair nearly one-coloured. Wings from base of shin. Fore- 

 arm-bone 1| inch long. 



Hab. North Australia, Port Albany. 



Nyctophiltjs gouldi 1 



Hab. North Australia, Port Albany. 



Dactylopsiea trivirgata, Gray, P. Z. S. 1858, p. 1 10. f. 1,5; 

 Gerrard, Cat. Bones B. M. p. 121. 



Var. Tip of the tail white. 

 Hab. Port Albany, North Australia. 



This animal was originally described from a specimen collected by 

 Mr. Wallace in the Aru Islands. 



Cuscus maculatus, var. ochropus. 



Male. Grey ; hair black, with grey tips ; the chin, throat, chest, 

 belly, scrotum, and some spots on the side of the back white ; tail 

 yellowish white ; feet yellow. 



Female. Larger, nearly uniform dark grey ; the hairs black, with 

 short grey tips ; chin, chest, and the middle of the belly to the vent 

 white, with a well-defined black streak on each side of the belly ; 

 tail yellowish white ; feet pale yellow. 



Hab. North Australia, Port Albany. 



A large female in the British Museum, which I described in my 

 paper in the ' Proceedings of the Zoological Society' under the name 

 of C. maculatus, agrees in many respects with the female from Port 

 Albany. The white on the abdomen is narrow and straight-edged ; 

 the dark colour near the white is well marked, but not so distinctly 

 as in those from Port Albany. It chiefly differs from the latter in 

 the feet not being yellow or reddish, which was common to all the 

 three specimens which I have seen from North Australia. 



The specimen of the two-thirds-grown female, described as Cuscus 

 brevicaudatus, which was brought by Mr. John Macgillivray from 

 Cape York, has a nearly uniform dark-grey fur, with the chin, 

 chest, and underside of the body white. It differs from the adult 

 female of Mr. Coxen's in the white on the under part of the body 

 being wider ; and there is no appearance of the broad black streak 

 which margins the white in the specimen from Port Albany. The 

 fore feet are grey like the back, and not yellow as they were in ail 

 the three specimens, which include two males and one female, sent 

 home by Mr. Coxen. 



Halmaturus coxenii, sp. nov. (PI. XXV.) 



Fur brown, minutely grizzled ; the nape and back between the
