Mr. R. F. Tomes on the genus Kerivoula. 477 



The tail is as long as the head and body, is composed of six joints, 

 and has its tip enclosed in the membrane. 



The fur of the back extends sparingly on to the interfemoral mem- 

 brane, for half its length ; and all its transverse lines are studded with 

 very short and fine hairs, scarcely idsible without the assistance of a 

 lens. The upper surface of the tail itself, and of the legs and feet, 

 is sparingly, but visibly, clothed with fine hairs, which are most conspi- 

 cuous on the latter. The whole of the margin of the interfemoral mem- 

 brane, inclusive of the os calcis, is fringed with fine hairs, those on 

 the OS calcis being adpressed and similar to those of the feet, whilst 

 those on the edge of the membrane are projecting and bristle-like. 



On no other part of the membranes does the fur of the body en- 

 croach ; but that of the head extends for half the length of the ears, 

 on their hinder surface. 



The fur of the body is very fine, but without gloss, and nearly 

 unicoloured. That of the upper parts is buif for two-thirds of its 

 length, the remainder a bright and lively rust-colour. Beneath, it is 

 uniform whitish buff, tinged with rust-colour on the humeral region 

 and along the sides of the body. 



All the bones of the limbs in the dried specimens are of a light 

 yellowish-brown ; and the interfemoral and interbrachial mem- 

 branes are of the same colour. A part of the wing-membranes con- 

 tiguous to the sides of the body, from the foot to the elbow, and 

 from thence along the under side of the fore-arm to the wrist, is 

 of a similar colour ; and it passes from the wrist along each finger, 

 margining it on each side, and leaving three triangular interspaces 

 between the digits, of a deep chocolate-brown colour, which in many 

 places is elaborately marked with dotted lines of the same light 

 colour as that which accompanies the wing-bones. 



The above description having been taken from dried specimens, 

 I copy the following description of the colour of this species from 

 the excellent account given of it by Dr. Kelaart in his ' Fauna Zey- 

 lanica' : — 



" Body above, yellowish ferruginous-brown, or, as artists would 

 call it, yellowish crimson-brown. Below, fulvous whitish, with a 

 dark yellowish tinge on the sides. Alar membranes black and bright 

 yellow or citron-coloured. The former colour (black) confined to 

 triangular spaces between the citron rays along the digits, and on a 

 large triangular space between the last digit and body ; the alar 

 membrane adjoining the latter being also citron-coloured. Inter- 

 femoral membrane wholly citron-coloured ; above and below the 

 arms also, the same yellow colour prevails, as through the other parts 

 of the membrane already mentioned." " Tips of toes brown, the 

 rest yellow." " Ears yellow." " Sexes alike in colour." 



As Dr. Kelaart is speaking of the species in its native country, 

 and from personal observation when in a fresh state, the foregoing 

 account is doubtless the correct one, and the comparatively dull co- 

 lour which pervades all the specimens in our Museums is due to a 

 change having taken place after preservation.

 men very kindly given to me by Dr. Horsfield, (2) from a specimen
