24 MAMMALIA PRIMATES. [VESPERTILIO. 



colour occupying the tips of the hairs, the roots of which are deep brown ; 

 under parts darker than the upper, the hair being grayish brown at the 

 tips, dusky at bottom : flying membranes dusky ; the portion contiguous 

 to the body very hairy ; a band of scattered hair also extends along and 

 beneath the fore arm, about five lines in breadth : upper half of the in- 

 terfemoral membrane both above and below likewise very hairy. Thumb 

 short: bones of the arm and fore-arm much slenderer than in the 

 Noctule. 



The only indigenous specimen which I have seen of this species is in 

 the British Museum. It is not known where it was taken. According 

 to Desmarest it resides constantly in hollow trees in large companies, and 

 is attached to the neighbourhood of stagnant waters.

oval, bending outwards, with a projecting lobe on the 

 inner margin ; tragus of equal breadth throughout : fur 

 above reddish brown, with the tips of the hairs white ; 

 beneath dirty white. 



V. discolor, Desm. Mammal, p. 139. 



DIMENS. Length of the head and body two inches four lines ; of the 

 head nine lines ; of the tail one inch five lines ; of the ears six lines and a 

 half ; of the tragus two lines and a quarter ; of the thumb three lines :

DESCRIPT. Forehead broad and hairy ; muzzle long, and very broad ; 

 nose thick and obtuse, measuring one line and two-thirds across the 

 extremity : eyes very small : ears shorter than the head, rounded, oval, 

 bending outwards and reaching almost to the corners of the mouth, with 

 a projecting lobe near the base of the internal margin, clothed externally 

 on their lower half with thick woolly hair ; tragus short, and nearly of 

 equal breadth throughout. Fur on the back reddish brown, with the 

 extreme tips of the hairs white, presenting a marbled appearance ; under- 

 neath dirty white, with a large patch of a somewhat darker tint covering 

 the breast and abdomen ; throat pure white. Tail protruding from the 

 interfemoral membrane to the extent of three lines. 



A single individual of this species, taken at Plymouth by Dr Leach, 

 is now in the British Museum. Said to be peculiar to houses, and 

 never to be found in trees.

 than the head, oval-triangular, deeply notched on their 

 external margins ; tragus nearly straight, terminating in a
