some new African Bats. 3d 
specimens, although the forearm measurement does not appear 
to be less. The head is therefore apparently rather smaller in 
proportion. 
Dimensions of the type (measured in flesh) :— 
Forearm 31 millim. 
Head and body 44; tail 35; ear 10. 
Skull: greatest length 12°5 ; basipalatal length 9°6; zygo- 
matic breadth 8; interorbital breadth 3:1; breadth of brain- 
case 6°7. 
Dimensions of a spirit-specimen ( ? ) :— 
Forearm 30. 
Head and body 42; tail 35; ear 11; tragus on inner 
edge 3°3; lower leg 13. 
Hab. Somaliland. Type from Hargaisa, 3500 feet ; other 
specimens from Berbera. 
Type. B.M. no. 98. 6. 9. 1. Collected 14th November, 
1897, and presented by R. McD. Hawker, Esq. Other 
specimens presented by E. Lort Phillips, Esq. 
This subspecies may be readily distinguished from the 
typical form by its far paler colour and prominently white- 
edged wing-membranes. 
Pterygistes azoreum, sp. n. 
Very similar to the other species, which scarcely differ 
among themselves except in size, but smaller than any of 
them. 
General characters, so far as can be made out on the single 
specimen, as in P, Letslerz, to which this form was assigned 
by Drouet and Peters *. But the size is markedly less, the 
general build is lighter, the ears appear to be rather broader 
and more rounded, while the tragus is slightly narrower and 
more pointed. 
Colour, in a spirit-specimen, apparently of the usual dark 
brown characteristic of Pterygistes. Hairs of back about 
6 millim. in length. 
Skull, as compared with that of P. Lezsler7, smaller and more 
delicate throughout, smooth, unridged, no sagittal and scarcely 
any lambdoid crests perceptible in an old male. Teeth 
practically identical throughout with those of P. Ledslerd. 
Dimensions of the type (an old male, in spirit) :— 
Forearm 37 millim. 
Head and body 54; tail 42; ear 12; tragus, length on 
inner edge 3, breadth 2; third finger, metacarpus 36:5, first 
phalanx 15, second phalanx 10°5; fifth finger, metacarpal 31,
