SECOND YAKKAND MISSION. 
* 
wing membrane between tlie 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. Pur 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. 
3. Vespertjgo discolor. 
Vespertilio discolor, Natterer, Kuhl. Deutsch. Flederm. Wetter. Ann. iv (1819). 
Vesperugo discolor, Keys. Bias. Wiegm. Archiv., 1839, p. 312. —Dobson, Mon. As. Chir., p. 106 ; Cat.

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. 
Pur 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 previou sly 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-
