EAST AFRICAN MAMMALS IN NATIONAL MUSEUM. 85 



Family HIPPOSIDERID^. 



Genus HIPPOSIDEROS Gray. 



1831. Eipposideros Gray, Zool. Misc., p. 37. (H. speoris.) 



1871. Ptychorhina Peters, Mon.-ber. K. Preuss. Akad. Wise. Berlin, p. 325. {E. 



caffer.) 



All the recognized forms of this genus of nose-leaf bats which are 

 knowji from the region are represented in the collection. 



HIPPOSIDEROS CAFFER (Sundevall). 



1847. Rhinolophus caffer Sundevall, Ofv. Kongl. Vet.-Akad. Forh., 1846, p. 118. 

 (Near Port Natal, Natal; type in Stockholm Museum.) 



Specimens. — Sixty, from the following localities: 



Uganda: Gondokoro, 30, including 21 in alcohol (Loring). 



British East Africa: Archer's Post, 1 (Heller); Juja Farm, 1 in 

 alcohol (Mearns) ; Kijabo, 1 in alcohol (Loring) ; Nairobi, 3, includ- 

 ing 2 in alcohol (Mearns, Heller, Loring) ; Nairobi River, 1 in alcohol 

 (Mearns); Northern Guaso Nyiro, 1 in alcohol (Mearns); Southern 

 Guaso Nyiro, 21 in alcohol (Heller). 



Zanzibar: Zanzibar, 1 in alcohol (Weddell). 



As will be seen from the accompanjdng measurements this species 

 is readily separable from the next by size alone. Although the di- 

 mensions of forearms "overlap," there is never the shghtest doubt 

 about which species a specimen should be referred to when the skull 

 is examined, and alcoholic specimens of the two species may be sepa- 

 rated easily by general bulk and by size and length of head. Among 

 our sixty specimens there are very few representing the red phase, 

 which seems to be rare, quite contrary to the case with the larger 

 species.^ In examining alcoholic material from the Southern Guaso 

 Nyiro, several specimens of the parasitic Nycteribiidse were found. 



HIPPOSIDEROS RUBER (Noack). 



1893. Phyllorhina rubra Noack, Zool. Jahrb., Syst., vol. 7, p. 586. December 23, 

 ("Lugerrunjere-Fluss," German East Africa; type in Berlin Museum.)

1910. Eipposiderus caffer centralis Roosevelt, African Game Trails, Amer. ed., 

 p. 474; London ed., p. 486. 



Specimens. — Eighty-nine, from localities as follows: 



Sudan: Bor, 1 in alcohol (Heller). 



Uganda: Gondokoro, 87, including 71 in alcohol (Loring). 



British East Africa: Nairobi, 1 in alcohol (Mearns). 



A large per cent of the specimens of this species are in the red 

 phase. The species is usually readily separable from Eipposideros 

 caffer by bulk alone; it is a much heavier animal, with decidedly
