 No. 166520, adult female in alcohol (skull removed). Collected 

 February 15, 1910, by J. Alden Loring. Orig. No. 9022. 



Description. — A small brown species related to Eptesicus capensis 

 somaliciis (Thomas), but with larger, flatter skull. Ears broad, 

 somewhat evenly triangular, with rounded tip ; when laid forward 

 reaching to tip of muzzle. Tragus comparatively long, broadest at 

 center, the tip bluntly rounded and not turned forward ; inner side 

 nearly straight for two-thirds its length ; outer side evenly convex 

 from tip to opposite anterior notch, where there is a small sharp 

 lobe, beneath which is a sharply concave margin and a larger tri- 

 angular basal lobe, immediately above the outer notch. Wing from 

 base of toes ; tail vertebrre entirely within the interfemoral membrane, 

 but a small fleshy tip extending very slightly beyond ; postcalcaneal 

 lobe comparatively small, sharply emarginate anteriorly and evenly 

 sloping posteriorly. Hair extending only slightly on to wings but 

 thinly covering the interfemoral membrane to line of ankles and. 

 along tail, to slightly beyond. Color (from alcoholic specimens) 

 apparently much as in souialicus but somewhat darker throughout ; 

 wings dark grayish brown, faintly lined along posterior edges with 

 bufit'y ; interfemoral membrane slightly lighter than wings. Skull 

 decidedly larger than in souialicus (as represented by specimens from 

 the Northern Guaso Nyiro) with relatively and actually broader 

 rostrum and braincase, and relatively much lower sinciput. Upper 

 inner incisors broad and heavy, distinctly bifurcate at tip (except in 

 a much worn specimen) ; outer upper incisors small, barely reaching 

 beyond cingulum of inner incisors. Lower incisors all trifid, con- 

 siderably crowded in the row. Cheek teeth essentially as in somaliciis 

 but slightly more robust.
