58 Rev. LEoNARD Jenyns on the Distinctive Characters 
vimanus, not only have the upper parts a reddish tinge, which 
in a slight degree pervades the ears, wings, and interfemoral 
membrane ; but what is more striking, they present a marked 
contrast with those underneath, which approach to yellowish- 
white. Moreover, it is worthy of note, that in this last species 
the hair is everywhere of the same colour throughout its whole 
length, whereas in the former it is of two Sakei being always 
blackish at the roots: - | 
I have contented myself on this occasion with mentioning 
those particularities which offer points of difference between 
the two species. Such as are the same in each, including the 
general appearance of the head and face, the singular formation 
of the nostrils, the peculiar shape of the auricle, tragus, &c., 
which are noticed with much accuracy in the Mammalogie of 
Desmarest and by other authors, I have not judged it necessary 
to speak of. B ee : 
It is Paps iaiagthat hazardous to form any conjectures on 
the habits of an animal from the case of a single individual, or 
we might have inferred, from the situation in which the above 
specimen of the P. brevimanus was found, that its natural place 
of abode was in the open country, remote from the habitations 
of men, and that during the hours of repose it retired to the. 
hollows of trees. In this respect it would differ widely from the 
P. auritus, which resides altogether in buildings, more particu- . 
larly within the roofs of dwelling-houses, where they may often 
be observed assembled in clusters of twenty or thirty together 
in the angles formed by the meeting of the rafters. 
This bat must certainly be rare in Cambridgeshire, from the 
circumstance of my never having seen a second specimen *; but 
it may be common elsewhere, and, as I hinted at the beginning, 
* Last summer (1827) I had an opportunity of again searching the neighbourhood 
of the spot where I first discovered this bat, but met with no success.
