Total length, 77.6 mm.; head and body, 44.6; tail, 33; forearm, 33; third meta- 

 carpal, 31.3; tibia, 12.6; foot, 9.1; ear from crown, 7.7; from notch, 12; length of 

 tragus, 5.8. 



Skull, total length, 13.7; condylobasal length, 13.1; zygomatic breadth, (?); 

 mastoid breadth, 7.6; interorbital breadth, 4.7; breadth of braincase, 6.7; maxillar 

 breadth, 5.4; breadth at canines, 4; upper toothrow (c-m 3 ), 4.5; length of mandible, 

 9.4; angle to condyle, 1.7; depth at coronoid, 3.4; lower toothrow, 4.8. 



Eptesicus garamboe, in size and external characters, resembles E. ugandce 

 Hollister, from Ledgus, Uganda, but exceeds it considerably in size, and 

 differs from it in the form of the tragus and other characters, the last caudal 

 vertebrae extending half its length beyond the membrane instead of wholly 

 enclosed within it as in ugandce. The skull proves, on comparison with 

 topotype skulls of ugandce, to not only exceed it greatly in size, but is much 

 broader and flatter, and the rostral portion much broader, the skull as a 

 whole much more massive and depressed.

Vesperugo (Vesperus) moloneyi Thomas, Ann. and Mag. Nat. Hist. (6), VII, p.

Four specimens, all adult males (2 skins with skulls, an extra skull and a 

 specimen in alcohol), collected as follows: Stanleyville, 1 (skin and skull), 

 Aug. 25, 1909; Medje, 2 (skin and 2 skulls), June 26, 1910; Avakubi, 1 

 (alcoholic), Dec. 19, 1913. 



Collectors' measurements of the two skins: Total length, 84, 85 mm.; 

 head and body, 58, 58; tail, 26, 27; foot, 6, 8; ear, 13, 15. 



Forearm (from skin), 27, 28.7; third metacarpal, 29, 30.6; third finger, 

 42.8, 44; fifth finger, 29, 30.6. Avakubi specimen (alcoholic), forearm, 

 28.2; third metacarpal, 28.8; third finger, 42.4; fifth finger, 30.4; foot, 6; 

 ear from crown, 7.4, from notch, 11. (Skull badly broken.) 



Three skulls, total length, 14.1 (13.8-14.3); condylobasal length, 13.7 

 (13.6-13.8); zygomatic breadth, 10.3 (10.2-10.3); breadth of braincase, 

 8.2 (8.1-8.2); upper toothrow, 4.6 (4.5-4.8). 



The remarkable reduction in the size of the wings of this species, as 

 mentioned by Thomas in his original description (/. c), and later made by 

 him the basis of the genus Mimetillus (Proc. Zool. Soc. London, 1862, II, 

 p. 188), is graphically shown by Chapin in Plate LV, and is the subject of 

 special comment in Part III, pp. 535-536, of this paper.
