present to leave the (jiiestioii open. — If Uh. dobsoni is, even 

 subspecitic-ally, inseparable from Rh. lo bat us , the species will 

 range from Kordofan and Gallaland in the north to Lower Zambesi 

 in the south. There would be nothing very surprising in this wide 

 distribution. As I have lately pointed out elsewhere (^) , another 

 Ethiopian Horseshoe-bat, viz. Hipposide^'us caffeo^ f. tyjpica, covers 

 ai)i)roximately the same, or, if anything, a still wider area, ranging 

 as it does from Kordofan and Erythrea, through British and German 

 East Africa and Nyasaland, to Transvaal, Natal, and Poiidoland. 



Rh. alcyone is by far tlie most completely differentiated ol 

 th.^ Ethiopian species here under consideration. In all important 

 cranial, dental and external features it is on the same level as 

 landeri and lobafus, but it is so much larger than the other 

 Ethiopian representatives of this type that there can be no doubt 

 as to its specific distinctness.
