Tasmanian Nyctophilus. 
Nyctophilus unicolor , Tomes in Proc. of Zool. Soc., part xxvi. p. 33. 
“ All the specimens of this genus I have yet seen from Van Diemen’s Land,” says Mr. Tomes, “ differ 
remarkably from those of the mainland of Australia, in having the fur everywhere short and cottony, 
perfectly devoid of lustre, and unicoloured ; that of the upper parts is of a dark olive-brown without any 
variation of tint, excepting that it is perhaps a little darker along the middle of the hack than elsewhere ; 
beneath the fur is similar but paler in colour, with the tips of the hairs a little tinged with ash-colour ; this 
is the colour of the whole of the under parts, with the exception of a patch on the throat, which is 
whitish brown, dirty white, and occasionally pure white. 
“ Immature examples often have the fur above and beneath of a very dark olive-brown, almost black. 
One specimen of this dark colour which I have examined has the spot on the throat almost pure white. 
“ So far as I have been able to ascertain, this species is subject to very trifling variations, either in colour 
or size in the adult state ; and the size agrees so closely with that of the species which I have called 
N. Gofildi, that I at first thought the great difference in the texture and colour of the fur was due to the 
difference of locality.” 
To this description I have nothing to add. The specimens in my collection were transmitted from 
Tasmania to this country by Ronald C. Gunn, Esq., a gentleman who has done much to enrich our know- 
ledge of natural history. 
The upper figure is of the natural size, the lower one somewhat reduced.
