1875.] MR. G. E. DOBSON ON THE GENUS TAPHOZOUS. 553 
This species very closely resembles 7. perforatus, Geoff., and may 
yet be shown to be a variety only of that species. The number of 
specimens of both species in the Museums at present is not sufficient 
to decide the question. 
Type in the collection of the British Museum.

Inner margin of the ear indistinctly papillate; tragus naked, with 
a distinct angular projection near the base of its outer margin.

On the upper surface the face in front of the eyes is covered 
with short hairs, and the fur of the back extends upon the inter- 
femoral membrane slightly beyond the point of perforation by the 
tail; beneath, the distribution of fur upon the membrane is similar, 
but the interfemoral is very thinly covered. 
Fur, above, from the base for three fourths its length light buffy- 
brown, then dark brown with grey extremities ; beneath, similar on 
shoulders and sides of the thorax and neck behind the ears as far 
back as the origin of the antehumeral membrane, the neck behind 
the gular pouch and the remainder of the chest and abdomen pure 
white. 
On the upper surface the wing-membrane as far outwards as a 
line drawn from the ankle to the elbow, and also the antehumeral 
and interfemoral membranes are brown, the remaining part of the 
wing-membrane white, except a small ill-defined patch of brown 
inside the first phalange of the longest finger; beneath, all the mem- 
branes are white. 
Length (of an adult male): head and body 3/1; tail 1-0; ear 
(anteriorly) 0'"8, tragus 0'25 ; forearm 2!'-4; thumb 0'"3; second
