■i56 Mr. K. Andersen on African Rhinolophi. 



Measurements of Rh. hipposiderus and Rh. h. minimus. 



Rhinolophus auritus and Rh. capensis. 



Rh. auritus*. — One type^ a full-grown male (mounted), 

 preserved in the Stockholm Museum, labelled " ^ perf. ; 

 Knysna, 3. iv. 1854 1; Victorin ; Grill 1859; Mam. Ex. 

 no. 1907." Peters J, who examined the type, which still 

 bears an additional label with his handwriting, regarded it 

 as " ein etwas jiingeres Thier " of Rh. capensis. Dobson § 

 has the name in his list of synonyms of Rh. capensis. 



Results. — Rh. auritus is indistinguishable from Rh. 

 cajiensis. The type may be called " ein etwas jiingeres 

 Thier/^ in so far as the teeth are still unworn, but the 

 epiphyses of the metacarpals and phalanges are not 

 separate. As the description drawn up by Sundevall on 

 closer study gives us a " key " to the riddle why that most 

 careful zoologist was led to regard Rh. auritus as a new 

 species, I think it of some interest to specialists to review 

 the points of difference enumerated by him. Rh. auritus is 

 stated to be: — (1) "affinis Rh. capensi ; paullo minor: 

 cubitus 45 mm." ; the forearm in the type specimen 

 measures (according to my method) 50 mm., in Rh. capensis 

 (11 specimens) it varies between 47*6 and 51*5 mm. :

t Probably a slip of the pen for 2. v. 1854. Only one specimen (the 

 present one) was brought home by Victorin.
