Hcib. Ndi, Taita, East Africa. 



An examination of a specimen of this species (named by the desoriber) 

 in the collection of the British Museum enables me to m^he the above 

 notes. A careful comparison of that specimen with specimens of Rh. 

 cethiops from Zanzibar, while showing the differences I have indicated, at 

 the same time shows also their close connection in all other respects ; and 

 I can scarcely regard Uh. Mlclebrandtii as more than a hill form of Bh. 

 cethiops, standing in much the same relation to that species as Vesperugo 

 lasiopierus to V. noctula, though differing much less in size than the liitter 

 variety. 



Trioenops persicus. 

 THcenops 2>ersicus, var. afer, Dobson, ' P.Z.S.' 1879, p. 717. 



An examination of two well-preserved spirit specimens of this species 

 in Dr. Robb's collection from Zanzibar, and of others sent to the British 

 Museum from Ushambola, enabled me to affirm the identity of the Persian 

 and African forms in the paper referred to aljove where I have compared 

 their measurements, &c. 



Hab. Persia (Shiraz) ; East Africa (Mombasa, Ushambola, Zanzibar). 



Phyllorhina tridens, Geoff. 



This species, as well as the preceding, extends into both Asia and 

 Africa. Specimens in the collection lately reeeived by the British Museum 

 from the India Museum ai-e labelled 'El Leil, Mesopotamia,' and 

 ' Bushire, Persia.' The basioccipital bone between the auditory buUre is, 

 in this species, proportionally much narrower than in other species of 

 Phyllorhina, and approaches that of Rhinolophus in this respect. 



Phyllorhina tricuspidata, Temm. 



To list of localities of this species add New Guinea (M. Raffray, 

 Paris Museum). 



Phyllorhina commersonii, Geoff. 



Add Malindi, East Africa (Fischer and Peters). 



Phyllorhina armigera, Hodgson. 

 Add Cochin China (M. Hai-mand, Paris Museum). 



Phyllorhina diadema, Geoff. 



Add also Cochin China (M. Harmand) ; Sanghir Island (M. Laglaize). 

 The specimens from the latter locality differ from all others hitherto 

 examined by me in the great development of the central projecting ridge of
