LVILI.— On a new Genus and Species of Vespertilionine Bat 
Jrom East Africa. By OLDFIELD THOMAS. 
Harpy had my description of Scotecus Hindei * been pub- 
lished than the Museum received from Dr. Hinde a second 
new bat, so distinct from all previously known as to require 
the formation of a new genus for its reception. 
It is the analogue of the South-American Histiotus in 
Africa, and may be called by a name having a similar 
meaning to that word— 
L2PHOTIS +, gen. nov. 
Most nearly allied to Vespertil’o, but the ear and tragus 
enlarged as in L/istiotus. 
Skull, as compared with that of the allied form, long and 
narrow, flattened above, very smooth and little ridged, the 
crests scarcely perceptible. Palate narrow, its posterior part 
unusually produced backward. Bulle rather large. 
Dental formula as in Vespertilo. 
Upper incisors close to canines, instead of being well sepa- 
rated from them, the tip of the lower canine biting on to the 
top of, or outside, the outer incisor, instead of between it and 
the upper canine. In correlation with this the lower canine 
is unusually short and feeble, its length from cingulum to tip 
not exceeding the outer horizontal length of m.'. Detailed 
proportions of teeth as described below. 
Type and only species 
Lephotis Wintont, sp. n. 
Size ratber less than in Histiotus velatus ; general appear- 
ance very much as in that species, although the ears are not 
so large. Fur close and fine, the hairs of the back about 
6-7 millim. in length. General colour above coppery brown, 
the basal halves of the hairs sooty, the terminal halves clear
