166 NTCTERID^. 



about the middle of its inner margin ; outer margin convex in its 

 upper half, the inner margin similarly convex throughout (Plate XI. 

 fig. 5). (The form of the tragus is therefore quite different from 

 that of any of the previously described species.) 



Fur varying in colour from dusky brown above and greyish 

 brown beneath to pale reddish brown on the upper surface, with 

 the whole breast and abdomen pure white. 



Second lower premolar minute, quite internal to the tooth-row. 



Length (of an adult 5 ), head and body 2", tail 2"-2, head 0"-8, 

 ear l"-2, tragus 0"-3x0"-18, forearm l"-75, thumb 0"-5, third 

 finger 3"-45, fifth finger 2"-55, tibia 0"-9, calcaneum 0"-65, foot 

 0"-4.

Dr. Peters distinguishes his N. angolensis from this species by the 

 darker colour of the fur, and by the greater size of the second small 

 premolar. The first character is extremely variable, and I believe 

 (from an examination of many specimens of different species of the 

 genus) that the size and position of the second small premolar vary 

 within certain limits, as in the closely allied genus Rliinolophus, to 

 an extent, however, sufficiently great to render the comparatively 

 larger size of this tooth in N. angolensis of little im.portance when 

 considered as a distinguishing character. I have therefore included 

 that form as a synonym of N. ihehaica. 



The next (?) species is closely related to this, and is distinguished 

 only by its longer ears and by the position of the second lower 

 premolar.

Ears longer than in N. thehaica, almost as long as in JSf. macroiis ; 

 tragus quite similar in shape. 



Pur generally similar in colour to that of N. ihehaica, but speci- 

 mens from certain localities (as N. fuliginosa, Peters, from Zanzibar) 

 are much darker throughout. 



The second lower premolar is minute, and stands in the tooth- 

 row, or is partially drawn inwards.
