710 CAPT.T. HUTTON ON HIMALAYAN BATS. [June 4, 



I strongly suspect Mr. Hodgson's Vespertilio muricola to be none 

 other than "this. Dr. Gray says of it :— " Feet large, elongate, half 

 free; tragus elongated, lanceolate, subfalcate." Mr. Hodgson did 

 not describe it. 



21. Vespertilio adversus. 



Vesp. adversus, Horsfield, Zool. lies, in Java ; Temm. Monogr. ii. 

 p. 221. 



This is a small species. The fur is somewhat long, dense, silky to 

 the feel, and slightly frizzled or wavy ; colour deep black, with the 

 tips hoary on the underparts, and in some lights with a faint tinge 

 of chestnut on the back ; ears and membranes also black ; nose, feet, 

 and claws the same, giving the animal a very sombre and lugubrious 

 appearance. 



The foot is very small, and in the wing to the base of the outer 

 toe, in the interfemoral to the ankle.

 Taken on 14th September. Another had the carpus l-Jy in. ; tibia 

 | in. ; ear § in. ; nose to tail Ijf ; tail 1| in. ; total length 3 T \ in. ; 

 expanse 9ff in. ; tragus T \ in., falcate. Taken the 30th September. 



A third, a male, had the carpus 1A in. ; tibia £ in. ; ear \ in. ; 

 nose to tail I j$ in. ; tail 1 T ^- in. ; total length 3 in. 



A fourth, a female, differed only in being from nose to tail ljfin. 



A fifth had the carpus \\ in. ; nose to tail lj|in.; in other re- 

 spects the same. These then, allowing for age and sex, are evidently 

 all the same species ; and all were recent specimens. 



The ears are wide apart, placed low on the side of the head, the 

 base being on a level with the gape, and the ear directed outwards. 

 The shape would be a long oval, were it not for the deep emargina- 

 tion of the outer edge, from which point to the base the lower part 

 of the lobe looks like a small second ear. The tragus is short, 

 pointing inwards, with an obtuse rounded top. 



This is a common species at Mussooree and in the Dehra Doom 

 It is early on the wing, coming out of caves and hollow trees, flying 

 high, and is very rapid in its movements. Like Vesperugo micropus, 

 when touched it opens the mouth wide, without emitting a sound, or 

 making the least attempt to escape or bite, and will thus keep on the 

 gape for several minutes, as if too much overpowered by sleep to be 

 at the trouble of shutting it again, allowing it gradually and slowly 

 to close, as if of its own accord. 



Genus Kerivotjla. 



Characters.— Feet half free ; face hairy ; ears lateral, diverging 

 outwards ; inner margin obtusely angular, outer margin rather sinu- 

 ated ; form, a long oval ; tragus slightly falcate, narrow, bending 

 outwards, half the length of the ear ; nostrils at the end of the 

 muzzle, divided by a slight notch; feet large; tail long; head 

 broad ; thumb long.
