Genus Nyctinomus found in Africa, &e. 37 
smaller and more widely-separated ears which form the sub- 
genus Mormopterus. 
SECTION I.—With incomplete premaxille. 
Nyctinomus africanus, Dobs. 
Colour reddish brown, lighter and brighter beneath. Ears 
and wing-membranes and muzzle brown. Ears distinctly 
separated on the forehead. Tragus large. 
Type in B.M. 
Forearm 66 millim. 
Skull very large and exceptionally broad, slightly arched 
on the forehead. The preorbital processes very much ex- 
panded, Premaxille separated, the opening perfectly circular. 
Incisors nearly parallel, or their points very slightly diver- 
gent. First upper premolar very small, blunt, the cusp 
barely longer than the cingulum. Lower incisors 4, of 
equal size. Lower canines almost touching at their bases. 
Transvaal. ; 
A rather smaller, white-bellied and light-winged form from 
Betsileo, Madagascar. 
Nyctinomus teniotis, Raf. 
Colour mouse-grey, very slightly, if at all, paler beneath. 
Ears and wing-membranes and muzzle black. Ears only 
united at extreme bases of their inner margins. Tragus large. 
Forearm 59-62 millim. 
Skull light and rather narrow, but very flat; forehead 
depressed. Premaxille widely separated.  Incisors con- 
vergent. First upper premolar of fair size, say larger than 
one of the cusps of the molars. ower incisors 6; the 
second pair largest; outer pair smallest and barely notched. 
Lower canines widely separated at their bases. 
Portugal, Italy, Greece, Persia. 
Nyctinomus egyptiacus, Geoff. ? 
The examples in the Museum seem to agree so thoroughly 
with Geoffroy’s description of this species, that, until typical 
specimens from Egypt are forthcoming to prove the contrary, 
I shall use this name for this 8S. African form. 
Colour in spirit-specimens as nearly as possible uniform 
all over: some black, some brown. Closely resembling 
NV. teniotis in all respects, but the ears are smaller and less 
broad; the lips, too, not so pendent. Tragus large. 
Forearm 47-50 millim.
