niinck's original description is so full that it furnishes a satisfactory 

 basis for comparison. In passing it may be remarked that the 

 Philippine bat referred by Dobson to E. monticola? is probably a dis- 

 tinct species from either the Javan or peninsular forms, as the dis- 

 crepancies in measurements are too great to be the result of mere 

 individual variation. 



From E. monticola the peninsular form differs chiefly in its larger 

 size (forearm 43-45 instead of 40, extent of wings about 280 instead 

 of 215-230) and longer tail (see table of measurements). None of 

 the Trong specimens show the snuff-colored head and fore-neck men- 

 tioned as occasionally occurring in E. monticola. The fur of the 

 ventral surface of the body is nearly as noticeably whitish at base 

 as that of the back, while in E. monticola it is said to be brown at 

 base. As shown in the table of measurements, Emballonura penin- 

 sularis slightly exceeds E. semicaudata in size. It is thus the largest 

 known species of the genus. 



Dr. Abbott secured seven specimens, all of which were sent to the 

 National Museum in formalin.
