Description. — Head large, flat, hairy. Snout high, emargi 

 nate, aud of a brown color. Nostrils opening sublaterally. Sides 

 of face moderately inflated. Mouth and lower jaw fi'inged 

 slightly with short hair. Small naked space at mentum. Ears 

 high, elliptical, pointed, and nearly naked — strongly convex on 

 their inner border, nearly straight on their outer — the lobe at the 

 base of the outer border well dev^eloped. The tragus similar in 

 shape to that of L. cinereus, but has a blunter incurved tip ; it 

 is slightly haired on facial surface. Eyes diminutive, placed near 

 the ear. Thumb rather small. Feet moderate. 



Fur not so extensive as in other species of the genus, posteriorly 

 extending upon the wing membrane from body, as in L. cinereus 

 — running down the interfemoral membrane but two-thirds 

 the distance and on to the foot ; a very small brownish tuft is 

 seen at base of thumb, and on the membrane at and above the 

 elbow, while the fourth and fifth fingers are naked. Anteriorly 

 the hair spreads up under the arm to wrist as in other species, 

 but less thickly. It also runs down a little way upon the inter- 

 femoral, and is observable upon the interbrachial membrane. The 

 wing membrane extends to base of toes. The calcaneum is 

 moderately developed. 



General hue olive brown. Hairs blackish at base, dirty brown 

 at centre, with a clearer tip. The color is somewhat darker 

 behind than in front.
