a new Taphozous from the Sudan. 143 
Size rather smaller than in hildegardee, decidedly larger 
than in sudani. General external appearance as to colour 
and distribution of fur much about as in perforatus and its 
allies. Fur covering, but restricted to, the body, short ; hairs 
of back barely 3 mm. in length. Colour above dark sepia- 
brown, the extreme tips of the hairs lighter, their bases 
white ; below similar, but paler, the light tips being longer. 
Throat with a sharply defined naked patch, no doubt indicating 
that the male has a gular pouch. 
Skull broad and stout, much more heavily built than that 
of ZT. sudani, and approaching that of the large 7. nudi- 
ventris, though its muzzle is conspicuously shorter than in 
that animal and is without the great projection forward of 
the incisors.. Forehead broad and flat, little hollowed out, the 
rise of the brain-case behind it not nearly so great as in 
sudant. Postorbital processes well developed, short. Brain- 
case broad, more parallel-sided, less oval, than in sudani. 
Mesoptery goid fossa penetrating the palate to the level of the 
hinder edge of m?. Basial pits broadly triangular, not very 
deep. 
Teeth as usual, rather stout and heavy throughout, breadth 
across canines greater than in other species of the same size. 
Dimensions of the type:— 
Forearm (c.) 66 mm.* 
Head and body 80 ; tail 35 ; third metacarpal 60. 
Skull: condyle to front of canines 22 ; zygomatic breadth 
15; interorbital breadth 7:3; intertemporal breadth 5 ; 
breadth of brain-case 11°2; mastoid breadth 13 ; palato- 
sinual length 6°25; postpalatal length 11:2; basial pits, 
length 3, combined breadth 5. ‘Teeth: front of canine to 
back of m? 9°73 front of p* to back of m? 6:5.

It is difficult to say to which of the older-known species 
this Yaphozous is most nearly allied. Its skull is much 
stouter than that of perforatus, sudani, and their allies, while, 
of course, the widely different fur-distribution of nudiventris 
and the peculiar colour of mauritianus at once separate those 
forms from it. TZ. hildegardee has a much narrower and 
* The proximal end of each forearm has been lost, and the length is 
estimated from that of the third metacarpal, usually rather more than 
one-tenth shorter.
