634 Mr. O. Thomas on 
hairy. Ears of average size, the projecting lobule at their 
outer bases very strongly developed, inverted, deeply con- 
cave externally, convex internally. Tragus with its free 
portion, as in WN. thebatca, expanded above and convex on 
its inner margin, but the free portion itself is barely one 
third its size in the allied species, the distance from its inner 
base to its tip considerably less than the distance from the 
same point to the base of the outer margin. 
Upper incisors deeply bifid; second lower premolar nearly 
half the size of the first, in the tooth-row. 
Dimensions of the type (measured in spirit) :— 
Forearm 45 mm. 
Head and body 52; tail 48; lower leg and foot (s. u.) 32°5; 
head 21°5; ear 28; inner margin of tragus 2°5. 
Hab. Efulen, Cameroons. 
Type. Adult male. Collected by Mr. G. L. Bates. Two 
specimens. 
This WVycterts is readily distinguishable by the extremely 
small size of the free portion of the tragus, which is other- 
wise similar in shape to that of JV. thebaica. 
Miniopterus inflatus, sp. n. 
Colour of MW. scotinus. Size larger than in MW. Schreiberst. 
Fur of back about 4 mm. in length, its texture about as 
in MV. scotinus, not extending on to the interfemoral or wing- 
membranes except close to the sides below. Colour uniform 
dark ‘seal-brown”’ above, rather paler below. ars and 
membranes black. 
Skull markedly larger than in IZ. Schreibersi, therefore 
still more exceeding that of the similarly coloured ©. scotinus. 
Dimensions of the type :— 
Forearm 46 mm. 
“Head and body 65; tail 48; hind foot 7; ear 11” 
(CER ipen)r 
Skull: greatest length 16:7; basal length in middle line 
12°3; front of incisors to back of m? 7:8. 
Hab. Efulen, Cameroons. 
Type. Adult skin (male). B.M. no. 3. 2.4.8. Collected 
24th July, 1901, by Mr. G. L. Bates. 
This Miniopterus is at once distinguishable from JZ. Schrev- 
bersi by its dark colour and large head, and from J. scotinus 
and Md. Newtoni by its much larger size. 
Nyctinomus thersites, sp. n. 
A medium-sized species, with proportionally short limbs, 
united ears, separated premaxille, and very small lower 
check-teeth.
