General remarks. — Kerivoula minuta is in no way closely related 

 to K. hardivickii or to any of the species hitherto known from the 

 mainland of Asia. Its relationships are wholly with the small 

 Bornean form recently described by Mr. Thomas as K. pusilla. 



Dr. Abbott secured only one specimen of this species. 



Emballonura peninsularis sp. nor. 



Type. — Adult $ (in alcohol), No. 83,575, United States National 

 Museum, Trong, Lower Siam, November, 1896. Collected by Dr. 

 W. L. Abbott. 



General characters. — In general appearance most like Emballo- 

 nura vionticola Temminck, one of the smaller" members of the genus, 

 but in size slightly surpassing E. semicaudata (Peale), the largest 

 species hitherto known. 



Ears. — Ears moderate ; when laid forward they extend slightly 

 beyond nostril. Anterior margin straight from base (over middle 

 of eye) to about middle, whence it is faintly convex to slight con- 

 cavity immediately below tip. Tip very narrowly rounded off. 

 Posterior border concave immediately below tip, then gently and 

 evenly convex to faint notch opposite base of tragus, after which it 

 is more abruptly convex to base, which is distinctly below line of 

 lower lip. Inner surface of conch with thirteen cross striations 

 arising near posterior border and disappearing shortly beyond mid- 

 dle. 



Tragus with anterior and posterior borders nearly parallel, though 

 on close inspection each is seen to be very faintly concave. As a 

 result the tragus is slightly narrower at mid height than at base or 

 immediately below the bluntly rounded tip. Whole periphery of 

 tragus faintly crenulate. A trace of a lobe on posterior margin just 

 below level of anterior base. 



Membranes. — The membranes are full and ample, but in no way 

 peculiar. Wings from ankles. Uropatagium including tail to base 

 of penultimate vertebra. Distance from tip of tail to free edge of
