with our specimen, which in lack of evidence to the contrary, may 
stand for the present as a full species. The subspecies fuscatus is 
described as dark smoky brown above, scarcely lighter below and 
without a white edging to the membrane, so is a very different animal. 
The inner upper incisor in P. marginatus is strongly bifid, and about 
twice the height of the outer. The first upper premolar is minute, 
not exceeding the cingulum of the canine, hence is invisible externally. 
It is not present on the left side of our specimen. The greatest length 
of the skull is 11.8 mm., of the tooth row, back of upper third molar | 
to front of canine 4. |

Five specimens of this white-winged species were collected at various 
points along the Blue Nile (Roseires, El Garef, Magangani) where it 
appeared to be fairly common. It commences to fly at dusk, and 
usually keeps fairly low, even coming close to the ground. More 
than once I knocked one down with a stick as it flew near me. 
I have compared the specimens with the original series from British | 
East Africa and do not find them essentially different.

A single specimen of this species was obtained at Bados on the Blue’ 
Nile, as it was flying about at the edge of a great marsh at dusk. 
Although in its present condition it is impossible to be certain of its 
color, it seems less pallid below than Thomas describes for the type.
