search of insects, cruuching the hard-winged beetles as it flies, with 

 a sharp crackling sound. It often flies so low as to be easily caught 

 in a common butterfly-net. It does not appear to be so abundant 

 as some other kinds, and does not ascend so high as Mussooree, but 

 in the summer rainy season is found at from 5000 to 6000 feet 

 elevation.

Rhinolophus rouxii, Temminck, Monogr. ii. p. 306. 



This species was taken by me at Mussooree and in the Dehra 

 Doon. 



At Mussooree, even at an elevation of 7000 feet, it makes its 

 appearance so early as March, remaining inactive d uring the winter, 

 but in the summer months coming forth from its retreat during the 

 very earliest hours of twilight, when it may be easily captured in a 

 butterfly-net while skimming over the surface of a pond or tank, or 

 wheeling rapidly, with somewhat devious flight, around the mountain- 

 oaks {Quercus incana) in search of prey. 



The colour of recent specimens is a rather light brown, in some 

 rather darker on the lower part of the back, beneath somewhat 

 paler ; fur soft, dense, and moderately long ; membranes dusky 

 black; expanse of wings 12| in.; carpus 2g in.; tibia \^ in.; 

 ear \^ in. ; from nose to insertion of tail 3 in. ; tail \^ in.; total 

 length of female 3^ in. The interfemoral membrane, as will be 

 seen by the shortness of the tail, is short, narrow, and straightened, 

 tending towards emargination about the end of the tail ; hairy to 

 some little distance below the vent ; the foot is in the wing to about 

 ^ in. above the ankle, and in the interfemoral to the ankle. 



Another female had the carpus 2 in. ; tibia \^ in. ; ear \\ in. ; 

 nose to tail 2|f in. ; tail -j-| in. ; total length 3ff in. The 

 length of the foot and claws from the heel is -\ inch ; a tinge of 

 maroon in the fur of the back. The females have 2 pectoral 

 mammae and 2 false pubic teats. The measurements of another 

 specimen, taken in September at about 5400 feet, where it flew into 

 the lights, were: — expanse of wings 13 in.; carpus 2g in.; tibia 

 |f in. ; ear \^ in. ; nose to tail 3g in. ; tail |f in. ; total 4 in. ; 

 long finger 3g in. ; heel bone 4- in. 



A specimen of this species sent to Calcutta for inspection was 

 returned labelled " Rhinolophus tragatus," which, if Messrs. Hodg- 

 son and Blyth's measurements are to be depended upon, it cannot 

 be. Neither of them notices the narrowness and semiemargination 

 of the interfemoral membrane, which constitutes so strongly marked 

 a feature in the species ; and, indeed, Mr. Hodgson at once does away 

 with such character by declaring the tail to be lg in., or 1 inch in 

 excess of mine ! 



Mr. Hodgson gives to his Nipal " tragatus," " length 2§ in., 

 and tail lg in.; expanse 15| in.;" which would give the total 

 length as 4^ in. Blyth gives the carpus as " 2\ in., and tibia 

 l^ 1 ,. in. ;" besides that, he says of the posteal nose-crest, " incon- 

 spicuous, being nearly concealed by the fur of the forehead."
