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 interferaoral 

 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 colours, 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. 



It is perhaps somewhat 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 ditler 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.
