Fur 3'5 mm. in length on the sliouUlors. General colour 

 sepia-brown, but tlie light bases of the liairs showing through, 

 especially across the shoulders, where the hairs are promi- 

 nently bufty wliitish for the greater part of their lengtli, the 

 tips only brown. Under surface dull buffy whitish, tlie 

 throat clearer wliite, but no\yIiere so pure a white as in 

 S. hirundo. Membranes blackish brown throughout. Tragus 

 short, broad, rounded, slightly incurved, the inner margin 

 concave. Wings to the end of the metatarsus. A distinct 

 postcaicarial lobule present. 



Skull, as compared with that o£ S. hirundo, larger, more 

 rounded, higher, and less flattened than in S. hirundo, and 

 still more so in comparison with the other species. The inter- 

 orbital broadening less noticeable than in any known species. 



Dentition as in S. hirundo, except that minute anterior 

 premolars are present on each side, standing in the notch in 

 the posterior base of the canines.

Hah. Kabwir, Northern Nigeria. Alt. 2500^ 



Type. Young adult female. B.M. no. 15. 10. 8. 1. 

 Original number 70. Collected July 28, 1915, and presented 

 to the National Museum by Dr. J. G. Fox. 



This species differs from S. hirundo by its larger size, 

 higher skull, and more obviously bicolor fur. The type of 

 S. hirundo is a very old female with worn teeth. 



Tiie inconvenient variability in the presence or absence of 

 the small upper premolars is a character of Scotiecas unique 

 in the Vespertilionidae. How far these teeth will prove to be 

 generally constant within each species remains to be seen, 

 but in S. hindei, at least, they are absolutely inconstant. 



The specific name is given in commemoration of Dr. Fox's 

 escape from the peaceful liner ' Falaba,' barbarously sunk on 

 its way out to Africa.
