18/2.] CAPT. T. HUTTON ON HIMALAYAN BATS. 699 



where it is very common, the colour is brown, with a slight tinge of 

 fulvous in some specimens, somewhat paler beneath ; membranes 

 dusky black. Male, carpus l-}-£ in. ; tibia -ft m - : ear It m - ; 

 nose to tail, in some 3 in., in others 3| in.; tail from J-| in. to 

 I in. ; total from 3J-^ in. to 4^ in. in others. 



Foot in both membranes to the ankles ; in some the extreme tip 

 of the tail is exserted, in others only to the edge of the membrane ; 

 interfemoral membrane straight and narrow ; longest finger 2| inches. 

 The female has 2 pectoral and 2 false pubic mammae. One female 

 had the carpus 2 inches. These are the measurements of seven speci- 

 mens, males and females. Ears acuminated, erect, semifalcate, 

 with outer lobe rounded, and divided from the interhelix as usual 

 by a notch. 



This Bat is on the wing from early in the spring to the end of 

 autumn. I discovered it, when taking an evening walk, coming out 

 by dozens from a narrow crack in a rock by the roadside on the hill 

 called at Mussooree the " Camel's Back," and while it was yet 

 quite light in the early evening. At a lower elevation I afterwards 

 observed that when the damp mists during the rainy season were 

 very thick, or the evening was dull and lowering, these Bats kept 

 within their cave and did not come forth at all, being thus some- 

 times imprisoned for two or three nights together. 



The facial crest is as usual in the genus ; but the posterior vertical 

 leaflet is exceedingly small as compared with that of the foregoing 

 species, being a mere narrow perpendicular stile crossed by a 

 narrow transverse bar sloping downwards.

This is a small species, with, as the name indicates, rather 

 unusually large ears for the size of the animal. The facial crest 

 much as usual ; but the central raised process is very much broader 

 in proportion than usual, and the posterior perpendicular membrane 

 is broad and somewhat elliptical in form. 



Carpus 1^ in ; tibia -ff in, ; ear 1 in. ; nose to tail 2\ in. ; tail 

 \\ in. ; total length 3^- in. ; expanse 9 in. ; longest finger 2| in. ; 

 tip of tail exserted. Colour brown, somewhat paler beneath ; mem- 

 branes and ears dusky black ; interfemoral membrane straight and 

 narrow ; feet in both membranes to the ankle. 



Another, which flew to the light in a room about 8 o'clock in 

 September, at 5530 feet, bad the carpus \\\ in. ; tibia \\ in. ; 

 ear 1 in. ; nose to tail 2^ in. ; tail 3 in. ; point of tail not 

 exserted (or perhaps broken off) ; interfemoral straight ; feet in 

 both membranes to the ankle. 



They come out of caves in the earlier twilight hours, and may be 

 seen flitting rapidly at some height in the air, chasing the small flies 

 and beetles which abound during the rainy season. The above 

 measurements are taken from recent specimens ; and although they
