Mr. 0. Thomas on Eiuballuuura. 139 



Emballonura cor, sp. n. 



Tragus and ears as in stresemanni. Basial pit lieart- 

 shapedj with three septa. 



Size about as in E. rafrayana. Colour INTars-brown, 

 slightly paler below. Ears narrowed tf.rminally, as in 

 stresemanni, not broad as in raffrayana. Tragus broad, its 

 breadth about half its length on inner margin, its inner 

 edge straight, its outer slightly concave. 



Skull of the same general shape as in rafrayana, but 

 rather narrow'er. Frontal region with a similar mesial 

 groove between the moderate facial inflations. No sagittal 

 crest in the type, which is fully adult. Opeuing of posterior 

 nares level with the lateral edges of palate, not contracted 

 anteriorly, its edge bi-concav.e, with distinct median point. 

 Mesopterygoid fossa long, its saddle-backed convexity low, 

 grooved mesially. Basial pit large, deep, sharply defined, 

 extending antero-laterally in front of tlie back of the meso- 

 ])terygoid fossa in two rounded lobes, separated from the 

 main part of the pit by low secondary septa; a well-marked 

 mesial septal ridge present. 



Teeth as in E. raffrayana, except that the inner lobe of p^ 

 has a less strongly developed anterior angle. 



Dimensions of the type (taken on the dry skin) : — 

 Forearm 38 mm. 



Tragus on inner edge 28 ; third finger, metacarpus 32"5, 

 first phalanx 9'3 ; lower leg and hind foot (c. u.) ^^2 ; 

 calcar 10. 



Skull : length from condyle to front of canine (c.) 12* ; 

 breadth across facial inflations 5*8 ; front of canine to back 

 of in^ 5 ; m} and m^ combined 2 3.

This species is readily distinguished from E. raffrayana 

 and stresemanni, the only foims with the same broad oblong 

 tragus, by its peculiarly shaped basial pit; from the former 

 also by its narrow ears and from the latter by the distinct 

 lateral septal ridges in the basial pit. 



Emballonura monticola, Temra. 

 In E. montico/a the basial pit is large, rounded, but rather 

 shallow, without deep or sharply defined limits. It has 

 normally distinct median and lateral septal ridges, dividing 

 it into four portions, but the lateral ones tend to be reduced 

 or obsolete in the eastern race (discolor) .
