JJab. Biserat, Jalor, Malay Peninsula. 



Ti/pe. Female. B.M. no. 3. 2. 6. 91. Collected and pre- 

 sented by Messrs. H. C. Robinson and N. Annandale, 



This beautiful little bat may be readily distinguished from 

 all its allies by its white belly and particoloured wings. Its 

 nearest relation is probably K. minuta, Miller*, also from 

 the Peninsula, but besides the differences in colour that species 

 has much longer fur (10 mm. on the back) and very differ- 

 ently shaped premolars. 



The type of Kerwula hicolor was captured during Messrs. 

 Robinson and Annandale^s expedition of 1901 to the Malay 

 Peninsula, but was accidentally overlooked when Mr. Bonhote 

 was preparing his account f of the mammals then obtained. 



Emballonura nigrescens solomonis, subsp. n. 



Similar in all essential characters to the true E. nigrescens, 

 Gray, but markedly larger. The head 14-14*5 min. in length 

 as against 13'0, the foramen 35—38 us against 32-34, and the 

 fifth finger 37-38 as against 33. 



The upper incisors vary in shape, being sometimes flattened 

 and more or less bicuspid, and sometimes conical and uni- 

 cuspid. In all the available specimens of true nigrescens they 

 are unicuspid.
