liavc rather more swollen brain-cases tlian in Javan speci- 

 mens. Small upper premolars not much crushed, // two- 

 thirds the size of />', half internal ; below, ^)g is quite in the 

 tooth-row, about half the size of //.

Forearm 37*5 mm. 



Head and body 46 ; tail 35 ; ear (anterior mari;in) 13 ; 

 tragus on inner edge 5 ; tibia 15 ; foot 9'5 ; calcar 12.

 breadth of brain-case 7"2 ; front of canine to back of m^ G;

Ti/pe. Adult female. BM. no. 0. 7. 29. 14. Collected 

 and j)resented by Dr. Charles Hose. 



This Baram bat ditfers from the Javan L. Jiorsjieldl by its 

 much smaller and narrower brain-case, and still more so from 

 the other Sarawak and N. Bornean examples of the group, 

 which have the brain-case more swollen than in true hors- 

 fiehJi. These other Bornean specimens I refer provisionally 

 to Miller's L. carhnatce, though I think it very doubtful if they 

 should be kept distinct from L. horsfeld't. But the skull of 

 L- lepidus is conspicuously difEerent from any of them.

 hind wing is darker and the submarginal patches smaller.
