In form and colour of the fur almost quite similar to V. noetula, but 

 differing remarkably in its much greater size and in the extent of 

 hair upon the wings. Ears and tragus precisely as in V. noetula, but 

 very much larger, and the upper half of the surface of the conch and 

 the flattened and reflected external margin thickly covered with erect 

 hairs ; the glandular prominences of the muzzle are greattly deve- 

 loped, and are covered with long straight hairs, which also extend 

 along the hps (Plate XII. fig. 4). 



The fur of the abdomen extends upon the wing-membrane very 

 densely as far as a line drawn from the knee to the elbow, and thence 

 outwards posterior to the forearm to the proximal fourth of the me- 

 tacarpal bone of the third finger ; along the fifth metacarpal bone 

 the wing-membrane is covered for nearly one inch in breadth ; 

 above and beneath, the interfemoral membrane is densely covered 



* These specimens from Chefoo, although undoubtedly referable to this 

 species, difier from all other specimens I have ever seen in the following 

 respects : — The outer margin of the ear is very shghtly folded backwards, the 

 tragus is larger, and the triangular lobe at the base of its outer margin very 

 acute. The prominences between the nostrils and eyes are much less developed, 

 and the inner margins of the nasal apertures project. Foot smaller and much 

 more slender ; the postcalcaneal lobe triangular, not rounded behind. Fur 

 very dark brown, with shining tips throughout. Lower incisors smooth, not 

 trifid. 



The completely ossified condition of the extremities of the finger-bones, and 

 the development of the pectoral teats, as well as the slightly worn condition of 

 the teeth, show that the specimens are quite adult.
