Saccopteryx pumilaj sp. n. 



Near S. canescens, Tlins., but the molars larger. 



External characters as in canescens, tliough the colour is 

 rather darker "^ as to be intermediate between the greyish 

 brown o£ canescens and the dark brown of leptura. 



Size of skull as in S. canescens, therefore conspicuously 

 smaller and more delicate than in S. leptura. Interorbital 

 and intertemporal region narrow. Anteorbilal inflation more 

 marked than iu either canescens or leptura, though less than 

 in Peropteryx. Postero-lateral edges of palate directly trans- 

 verse, not slanted backwards towaids the middle as iu 

 S. leptura. Mesopterygoid fossa narrow. Basisphenoid pit 

 without narial septum. Foramina between the outer corners 

 of the pit and the glenoid surfaces quite small, as in S. canes- 

 cens, much larger in S. leptura and gymnura. 



Molars conspicuously larger than in 8. canescens and 

 gymnura, nearly equalling those of S. leptura.

Forearm 37*5 mm. 



Skull : greatest length 13'7 ; condylo-basal length to front 

 of canine 11"3; zygomatic breadth 7*7 ; interorbital breadth
