12 SECOND YARKAND MISSION. 
wing membrane between the fourth finger and the foot is faintly margined with white ; th e 
outer upper incisor, on each side, is as long or slightly longer than the outer cusp of 1 1 
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 o 
the second premolar. Fur pale yellowish-brown above, yellowish- white beneath ; the bas» 
half of the hairs dark-brown on both surfaces. The hair of the back extends upon the 
interf emoral membrane rather densely as far as the end of the fourth caudal vertebra ; a fring e 
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, difh' 1 ' 
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 ^ 
pipistrellus. Outer upper incisor, on each side, small, not equal to half the vertical exten 
of the inner incisor ; first lower premolar short and blunt, not half the vertical extent oi 
the second premolar ; lower incisors not crowded, placed in the direction of the jaws. 
Fur similar in colour to that of V. borealis, extending less densely upon the interfernorfd 
membrane, and not forming a fringe along the upper lip in front beneath the nostrils. Th lS 
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 fr oJ3J 
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 ^ 
has received not less than seven different names. The specimens obtained by Dr. Stolid ‘ 
in Kashmir differ from European forms in the colour of the fur only, which is pale-bi‘0' v 1 
above and almost white beneath, the basal half of the hairs on both surfaces being dark.
