SECOND YARKAND MISSION. 



wing membrane between the fourth finger and the foot is faintly margined with white ; the 

 outer upper incisor, on each side, is as long or slightly longer than the outer cusp of the 

 inner incisor ; the lower incisors stand at right angles to the direction of the jaws ; the 

 first lower premolar is about two-thirds the vertical height, but scarcely one- third the size of 

 the second premolar. Fur pale yellowish-brown above, yellowish-white beneath ; the basal 

 half of the hairs dark-brown on both surfaces. The hair of the back extends upon the 

 interfemoral membrane rather densely as far as the end of the fourth caudal vertebra ; a fringe 

 of fine straight hairs extends round the upper lip in front, beneath the nostrils, and along the 

 sides.

One specimen taken at Kizil. 



This agrees in all its principal characters with European specimens of the species, differ- 

 ing slightly in the form of the tragus, which is less broad above, reaching its greatest width 

 about the middle of its outer margin. Post-calcaneal lobe distinct, rounded as in V. 

 pipistrellus. Outer upper incisor, on each side, small, not equal to half the vertical extent 

 of the inner incisor ; first lower premolar short and blunt, not half the vertical extent of 

 the second premolar ; lower incisors not crowded, placed in the direction of the jaws. 



Eur similar in colour to that of V. borealis, extending less densely upon the interfemoral 

 membrane, and not forming a fringe along the upper lip in front beneath the nostrils. This 

 absence of a thin fringe of hairs along the upper lip below the nostrils affords an easy 

 method of distinguishing badly preserved skins of immature specimens of this species from 

 V. borealis. This has not been previously noticed.

Kashmir. 



This species is so widely distributed, and varies so much in the colour of the fur, that it 

 has received not less than seven different names. The specimens obtained by Dr. Stoliczka 

 in Kashmir differ from European forms in the colour of the fur only, which is pale-brown 

 above and almost white beneath, the basal half of the hairs on both surfaces being dark.

Yangihissar. 



The single specimen in the collection agrees in the form of the ear with specimens exam- 

 ined by me from Darjiling, the Khasi Hills, Masuri, Simla, and other Himalayan local-
