Glossonycteria, Peters, MB. Akad. Berl. 1868, p. 365. 



General characters those of Lonchoglossa, with which this genus 

 also agrees in the dental formnla, but differs in the form and arrange- 

 ment of the teeth and in the non-develox)ment of the zygomatic 

 arches.

Muzzle and nose-leaf as in Ischnoglossa nivalis, the anterior angle 

 of the eye is equally distant from the tragus and the extremity of 

 the muzzle ; ears slightly more than half the length of the head, 

 rounded off above, the outer margin of the ear-conch deeply concave 

 in its upper half, then convex, again emarginate opposite the tragus, 

 thence convex to the base ; tongue as in G. soricina, the sides very 

 thickly set with long filiform papillae. 



Thumb considerably shorter than the foot ; wing-membrane from 

 the distal third of the tibia ; interfemoral very short, the emargina- 

 tion extending upwards as high as the proximal third of the tibia ; 

 no trace of a tail externally ; calcaneum rudimentary ; feet large, 

 nearly as long as the tibia. 



Fur, above, dark brown, the basal half or three fourths of the hairs 

 pale buff-brown ; beneath, brown at the base of the hairs, the extre- 

 mities greyish brown. The wing-membrane is clothed on the upper 

 surface almost as far outwards as a line drawn from the elbow 

 to the knee, and the fur extends thickly along the legs and upon 

 the narrow interfemoral membrane to the ankles ; the greater part 

 of the antebrachial membrane is thinly covered, and some hairs 

 appear upon the metacarpal bone of the thumb ; beneath the wing- 

 membranes are nearly naked, but the margin of the interfemoral has 

 a long fringe. 



Upper outer incisors larger and longer than the inner ones, which 

 are round and obtusely pointed, the outer incisors triangular and 

 subacute ; first upper premolar scarcely one third the size of the 

 second, with an oblique cusp and a small posterior basal x^rojection 

 placed in the posterior part of the wide space between the canine 

 and second premolar ; second premolar very narrow, with an acute 

 cusp and a prominent basal projection in front and behind, nearly 

 equal in antero-posterior diameter to the third premolar, which 

 exceeds it in vertical extent ; molars with small W-shaped cusps and 

 horizontal flat internal basal projections, the last molar equal to three 

 fourths the antepenultimate molar, with a V-shaped cusp. 



In the lower jaw the incisors are deciduous ; the three premolars 

 are as large as the second upper premolar, the first is close to the
