256 New Species of Macroscelides and Glauconycteris. 
Glauconycteris beatria, sp. n. 
A small blackish species of the group with brown unicolor 
wings. 
Size rather less than in G. poensis. General colour above 
and below uniform blackish brown without lighter markings; 
wings and interfemoral membranes uniformly brown through- 
out. Muzzle broad and tumid; lobes at corner of mouth 
well developed. Inner margins of ears extremely convex 
forwards, forming, from the rounded basal lobe to the tip, 
approximately the half of a circle; tip scarcely perceptible ; 
outer margin straight above, then convex, with a well-marked 
angular antitragal lobe. 
‘Tragus short, fairly broad, its inner margin straight, its 
tip rounded, its outer margin evenly convex, with a well- 
marked basal lobule. 
Wings to the base of the toes. No postcalcareal lobule. 
Tail included in membrane to its extreme tip. 
Skull, as compared with that of G. poensis, smaller, more 
delicately built, and with a narrower muzzle. 
Inner upper incisors with the secondary cusp longer and 
more widely separated from the main one than in G. poensis ; 
- outer incisor fairly large, pressed against the canines behind, 
and reaching vertically about half the height of the secondary 
cusp of 2’; in transverse section it appears to be about half 
the area of the same tooth. In G. poensis it is shorter, smaller 
in area, and is separated on each side from the canine. 
Lower incisors bifid, slightly overlapping. Anterior lower 
premolar with a long well-defined main cusp half the height 
of the posterior premolar. 
Dimensions of the type (measured in spirit) :— 
Forearm 39 millim. 
Head and body 45; tail 43; ear 10; tragus on inner 
edge 3; middle finger, metacarpal 38, first phalanx 13:5, 
second phalanx 23; lower leg 19°5; hind foot (c. u.) 75; 
calcar 13. 
Skull: occiput to gnathion 11°1 ; interorbital breadth 4°2 ; 
breadth across brain-case 7; front of canine to back of 
m* 4:2. 
Hab. Benito River, French Congo, fifteen miles from 
mouth. 
Type. Female. B.M. no. 98.5. 4.19. Collected January, 
1898, by Mr. G. L. Bates. 
The only near ally of this species appears to be G. poensis, 
and from that it is readily distinguishable by its smaller size,
