Mr. K. Andersen on African Rhinoloplii. 455 



Measurements of Rh. acrotis and Rli. a. Andersoni. 



Rhinolophus minimus and Rh. hipposiderus. 



Rh. minimus'^. — The type, an immature but full-grown 

 male (in alcohol), preserved in the Stuttgart Museum, is 

 labelled ''No. 987; Keren, v. Heuglin; 1862." It was 

 identified by Peters f with Rh. hipposiderus, Dobson |: 

 adopted this view. 



Results. — Rh. minimus is undoubtedly referable to Rh, 

 hipposiderus as a sjjecies. It has the decisive characters 

 of this latter, above all : (1) the comparatively well- 

 developed upper p'^, placed entirely in the tooth -row; 

 (2) the long and very narrow sella, with the lateral margins 

 con^'crgent towards the summit, the summit itself sharplv 

 pointed; (3) the 5th metacarpal shorter than or, at most, 

 equal to the 4th. But it is decidedly smaller and, especially, 

 shorter-tailed. There is in the British Museum a speci- 

 men from Sennar ( ? ad., in alcohol, no. 47. 5. 27. 48) 

 exactly like the type of Rh. minimus. This form therefore, 

 probably, should be kept distinct as a small short-tailed race 

 of Rh. hipposiderus.
