I have some reason to think that also de Seabra's Rh. ango- 

 lensis ( l ) , known from one example , in the Lisbon Museum , 

 obtained at Hanha, Angola, is a species of the Rh. landeri type. 

 p 2 is stated to be in the tooth-series (« denticao como no Rh. 

 hipposiderus », in the Portuguese account; « la petite premo- 

 laire superieure tres peu saillante mais assez large et serree entre 

 la canine peu developpee et la seconde premolaire longue et aigiie » , 

 in the French version) ; and judging from two pencil-sketches of 

 the nose-leaves, very kindly sent me by Sr. de Seabra, the con- 

 necting-process is projecting and pointed, and the sella pandurate. 

 These three facts combined seem to exclude all doubt as to the 

 true affinities of Rh. angolensis. — The fourth metacarpal 

 measures, according to Seabra, 32 mm., the first phalanx of the 

 fourth digit 7 mm.; in other words, this phalanx shows the strong 

 shortening so characteristic of the bats of the landeri type. — 

 The other measurements published seem to indicate that Rh. 

 angolensis comes nearest to Rh. landeri in external dimensions, 

 being perhaps a trifle smaller, and with a markedly shorter tibia. 

 The skull is unknown. 



If my suggestion as to the affinities of Rh. angolensis is 

 correct, the Rh. landeri type — thus comprising Rh. alcyone, 

 landeri, angolensis, lobatus, and dobsoni — is, roughly speaking, 

 distributed in a broad belt across tropical Africa, from the Gold 

 (.'oast, Kordofan and Gallaland in the north, to Angola and Lower 

 Zambesi in the south.
