a new Taj)liozous//om the Sudan. 143 



Size ratlier smaller than in hilJegardece, decidedly larger 

 tliai) in Sudani. General external appearance as to colour 

 and distribution of tur much about as in perforatns and its 

 allies. Fur covering, but restricted to, the body, sliort ; hairs 

 of back barely 3 muK in length. Colour above dark sepia- 

 brown, the extrenie ti()S of the hairs lighter, their bases 

 white ; below similar, l)ut 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 tliati that 

 of 2\ Sudani, and approaching that of the large T. nudi- 

 ventris, though its muzzle is conspicuously shorter tiian in 

 that animal and is without the great projection forward of 

 the incisors. Foiehcad broad and flat, little hollowed out, the 

 rise of the brain-case behind it not nearly so great as in 

 Sudani. Postorbital processes well developed, short. Brain- 

 case broad, more parallel-sided, less oval, than in Sudani. 

 ]!ile.sopterygoid fossa penetrating the palate to the level of the 

 hinder edge of nr. 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.

 15 ; interorbital breadth 7*3 ; intertemporal breadth 5 ; 

 breadth of brain-case 11'2 ; mastoid breadth 13 ; palato- 

 sinual length Q'2 ; jwstpalatal length 11'2 ; basial pits, 

 lengtii 3, combined breadth 5. Teeth : front of canine to 

 back of 7u' 9*7 ; front of y/ to Lack of m^ 6*5.

It is difficult to say to which of the older-known species 

 this Tdphozous is most nearly allied. Its skull is much 

 stouter than that oi 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. T. hlldegardeo! 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 

 oue-teuth shorter.
