2. MOKMOPS. 457 



this process, which arises from the posterior margin of the conch, is 

 as high as the summit of the ear, from which an angular notch 

 separates it, and its anterior prolongation extending forwards upon 

 the muzzle is united with its feUow of the opposite side at a short 

 distance hehind the extremity of the muzzle, differing remarkably in 

 this respect from M. megalophylla, in which the anterior prolonga- 

 tions of the inner margins of the ears, though very close together 

 in front, are not united ; the tragus terminates above in a triangular 

 instead of in a rounded process, and in front of its base the inner 

 surface of the ear-conch supports a round process quite different from 

 the corresponding longitudinal low ridge in the other species ; the 

 wart, also, near the posterior commissure of the eyelids is placed di- 

 rectly behind, not in a plane inferior to the eye (Plate XXIII. fig. 6). 



The sides of the upper lip have two distinct fleshy processes — one 

 immediately behind the nostril, a conical longitudinal process, the 

 second opposite the first upper premolar, a long slender process 

 standing at right angles to the lip ; near the angle of the mouth, 

 opposite the second premolar, the upper lip is notched, as in M. 

 megalofliylla, biit a much deeper and more projecting lobe is thus 

 cut off which projects directly forwards from the angle of the mouth 

 (Plate XXIII. fig. 6). 



The central cutaneous process hanging from the front surface of 

 the lower lip is not divided beneath by a vertical incision ; its lower 

 and upper margins are slightly concave and its sides straight ; from 

 the centre of its lower margin two small projections are directed 

 downwards (Plate XXIII. fig. 6). 



Wing-membranes and extremities as in the other species. The 

 acute extremities of the calcanea project nearly 0-1 inch beyond 

 the interfemoral membrane. 



Fur bright orange throughout ; quality and distribution as in M. 

 megalophylla. 



The following notes by the late Mr. W. Osburn are derived from 

 an examination of a recently killed specimen: — 



" Volar membrane semitransparent, and tissue so thin it dried 

 almost before I had finished preparing the specimen; much wrinkled 

 between elbow and hand into angular plicae like shagreen. Nerves 

 of interfemoral very beautiful when held against the light; one 

 central in line of tail, giving off at right angles pairs of branches 

 like a pinnate leaf. Fur bright chestnut, above rather paler ; very 

 long, silky, and soft. Eound the shoulders it is longer, so as to 

 form a narrow frill longer than the rest." 



Mr. Osburn also noticed the " extreme fragihty and thinness of 

 its whole structure. The light was visible through the roof of the 

 open mouth. ... The tail was curled upwards so as to carry the 

 interfemoral with it ; this was caused by the calcaneum bearing up 

 the interfemoral. Femora long ; so that when reposing the knees 

 were above the back, like a grasshopper's. ... It easily took wing 

 off a flat surface, and its efforts to escape during the night broke some 

 of the phalangeal bones. ... It refused flies, but it drinks greedily. 

 The tongue was protruded ; but the water taken up by it and the
