the same iu outline as M. hlainvillii, but the lower margin deeply 

 divided between the two processes, the incision being widened 

 at the end, the margins adjoining these processes but slightly 

 eraarginate with the lower angles rounded; surface of lappet 

 similar to M. hlainvillii. Labial fold very much as in the above- 

 mentioned species.^® 



Limbs. — Forearm long, metacarpal of the third finger not 

 reaching the elbow; thmub short and weak. Tibia and femur 

 slender. 



Fur. — Fur rather sparse in the region of the nape, the crown, 

 of the head being devoid of hair. Upper fur silky, under fur 

 woolly. 



Color. — Upper surface prout's-brown, the hair lighter basally, 

 which under tint shows in the sparsely haired region of the nape, 

 imparting a dull ochraceous touch to that portion. Membranes 

 clove-brown. Under surface varying from wood-brown to taAvny- 

 olive. 



Skull. — Rather large, strongly inflated, brain-case capacious, 

 gently curving down into the rostrum which is strongly inflated 

 posteriorly. Zygoma not bowed, widest posteriorly. Basi-crauial 

 axis forming an obtuse angle with the facial axis. 



Teeth. — Middle upper incisors broad, with a faintly bilobed cut- 

 ting edge ; outer upper incisors minute, placed in close proximity to 

 the middle incisors. Lower incisors aiTanged in a semi-circle, each 

 finely trilobed. Upper canines long, slightly divergent at the tips. 

 Lower canines rather long, divergent, with the cingulum well 

 marked posteriorly. First upper premolar low, conical, slightly 

 directed inward; second premolar with the external cusp long, 

 hastate, the internal portion forming a low roimded shoulder, the 

 basal proportions of the tooth being longer (on the external mar- 

 gin) than wide. Lower premolars conical, the second shorter iu 

 lateral outline than the first or third, the latter more attenuate than 

 the others. Upper molai-s broad, the first and second w4th 

 AV-shaped external cusps, the internal paraconoid ridge heaviest 

 anteriorly, posteriorly low and free from the external cusps; third 

 molar with a V-shaped pattern, the metacone not being developed, 



" Dobson's figure (Catal. Chiropt. Brit. Mus., PI. XXIII, fig. 5) of this 

 Bpecies shows the chin-lappet quite diflferent in form from that of 31. 

 blainvillii. This is not so aiiparent in my specimens and was probably 

 due to a disarrangement iu the specimen figured.
