Genus Nyctinomus found in Africa, &e. 39 
SECTION II.—With completely ossified premaxille. 
Nyctinomus limbatus, Pet. 
Kars connected by a deep band. Tragus small. 
Colour above dark reddish brown; the underside, except 
chin, throat, and sides of the body, white. Long crest of 
erect hairs behind the connecting membrane of ears in the 
males, Wing-membranes canary-yellow, covered with white 
fur from the middle of the humerus to the heel. Inter- 
femoral membrane palish brown. Wings from ankles. A 
6, 82.2.6.15, Zanzibar, is very dark-coloured above and 
below, with no white on the belly, but with whitish fur on 
the wing-membranes ; the wings themselves are not quite so 
brightly coloured as usual. 
Forearm 36-38 millim. 
?, 93.12.2.8., Tana R. Slightly larger, wing 38 millim. ; 
wholly brown, with the exception of fur on the wing- 
membranes, which are very brightly coloured, and a narrow 
white streak on lower belly including genitals. 
Skull very flat, with low crest from constriction ; upper 
incisors close together ; premaxille completely ossified ; first 
upper premolar a little pinched on to the outer side of the 
tooth-row. Lower incisors with high inner cusp. 
Kast Africa. Madagascar. 
Nyctinomus gambianus, sp. n. 
Much resembling N. limbatus in size and general appear- 
ance, but differing in having the lower parts uniform brown. 
The skull also closely resembles that of the East African 
species; but in this new bat the first upper premolar is only 
vestigial, so small, indeed, that it is not possible to see it 
without the aid of a strong lens. This minute tooth is 
placed close against the canine, in the outer angle formed by 
the actual meeting of the canine and second premolar. The 
first lower premolar is also smaller in this species. 
Forearm 37-38 millim. (type). 
The males are not furnished with the crest of long hair on 
the back of the membrane connecting the ears, which is such 
a characteristic feature in VV. imbatus from K, Africa. 
Gambia, Lagos, Nigeria. 
Type, 6, B.M. No. 89.10.7.8. Gambia. Collected by 
Dr. Perey Rendall. 
A specimen referable to this species formed the basis of 
Dobson’s description of N. pumzlus.
