Forearm, from skins, same specimens, cf-43.6 (42-44.7), 9 44.2 (43.4-44.9). 

 Skull, 5 males, 6 females: Total length, & 14.6 (14.3-15), 9 14.7 (14.4-14.9); 

 breadth of braincase, d" 7.4 (7.2-7.6), 9 7.5 (7.3-7.7). 



The present form is similar in general coloration to M . breyeri breyeri, 

 from the Waterberg District of the Transvaal, with two topotypes of which 

 the present series has been compared. The pubic region is pale fulvous, 

 however, instead of white, and the average size is considerably less, the 

 forearm in breyeri having a length (3 specimens) of 46 mm. and in mcinior 

 (16 specimens) 43.5, the largest specimen of the latter being smaller than the 

 smallest of the breyeri specimens. Jameson 1 gives the length of. the skull 

 in breyeri as 15.5; the average in mcinior is 1 mm. less, only one in a series 

 of 12 skulls reaching 14 mm. 



M. breyeri mcinior is readily separable from the M. natalensis group by 

 its paler, much browner coloration and by other features, as shown by 

 direct comparison with typical natalensis and with topotypes of natalensis 

 arenarius.

Thirteen specimens (9 males, 4 females, all adult, in alcohol), Thysville, 

 Lower Congo (midway between Matadi and Leopoldville), June 2, 1915. 



Forearm, 9 males, 45.2 (44.3-46), 4 females, 44.4 (44.2-44.9). Five 

 skulls (3 males, 2 females), total length, 15.9 (all 15.9), 9 15.5 (15.3- 

 15.7); zygomatic breadth, <? 8.63 (8.6-8.7), 9 8.65 (86-87). The females 

 are slightly smaller than the males. 



Pelage uniform blackish brown (nearly black) both above and below; 

 ears and membranes dark brown, somewhat lighter colored than the 

 body. (Figs. 23 and 24, pp. 540, 541, head of male, and left wing showing 

 the tip folded.) 



These may doubtless be safely referred to M. inflatus, described from 

 an adult male skin from "Efulen, Cameroons," of which the forearm length 

 is given as 46 mm. and the greatest length of the skull as 16.7, the latter 

 slightly more than the largest of my series of five skulls.
