openings through the eyes to the upper lip, naked, or nearly so ; 

 but the upper lip is fringed with scattered short bristly hairs. The 

 extreme margin of the lips, both above and below, are naked and 

 smooth. 



That part of the wing-membranes which is contiguous to the 

 under surface of the body is a little hairy ; and the fur of the rump 

 extends, to a very trifling degree, on to the interfemoral ; but all other 

 parts of the membranes are perfectly naked. 



On all parts of the body the fur is rather soft, thick, and long, 

 and perfectly devoid of lustre. It is also perfectly unicoloured 

 everywhere, being above of a deep sooty brown with a slight tinge 

 of rusty, and similar, though a little paler, beneath. 



Upper incisors, 4, in pairs as in Vespertilio ; they are very small, 

 narrow near the alveolus, and blunt at the tips. Upper canines 

 furnished with a kind of lobe or talon behind, at the base ; the 

 lower ones with a similar one in front. Lower incisors very small, 

 symmetrically ranged, and with their cutting edges lobated.

Hab, "Island of Ovalee (Figi Islands), August 1856, H.M.S. 

 ' Herald,' F. M. Rayner." Such was the label attached to the spe- 

 cimen when it recently reached Dr. Gray, through whose kindness I 

 am enabled to give the above description. 



Obs. Several species of Cheiroptera have fur of much the same 

 quality and appearance as this species. Nyctophilus unicolor, from 

 Van Diemen's Land, Molossus norfolcensis, Norfolk Island, and 

 M. acetabulosus, Mauritius and Natal, are amongst these ; and the 

 American species M. nasutus also has fur which approaches closely 

 in texture that of all these species. 



The present species, although it differs materially from E. mon- 

 ticola, yet bears greater resemblance to it in the form of the head, 

 ears, &c. than to any other species. To the African species, E. afra 3 

 Peters, it has some similarity in the form of the snout ; and all these 

 three are species which appertain to the genus Emballonura as
