228 Miller — A New Bat from German East Africa. 



of the secondary lobe of the tragus in the type specimen as compared with 

 that figured by Dobson and represented by a Sierra Leone specimen in the 

 United States National Museum. In the skin from Taveta this lobe has a 

 form intermediate between the others and closely resembling that of Lavia 

 froiis as figured by GeofFroy. The variation is probably individual. 



SkaJl and Teeth. — As compared with those of an adult male Lavia frovs 

 from Sierra Leone (No. 38,196, United States National Museum) the skull 

 and teeth of Lavia rex are readily distinguishable by their uniformly greater 

 size and massiveness. In actual form of either skull or teeth there are no 

 striking differences between the two species ; but the larger animal has 

 the audital bullae relatively larger and the interpterygoid space narrower, 

 while the teeth, particularly the upper canines and upper molars, are very 

 considerably increased in size.
