TYPICAL BATS. 27 



county; while it has also been recorded from Warwickshire 

 (where it is not uncommon), Cambridgeshire, Northampton- 

 shire, Norfolk, and Suffolk. According to Mr. Montagu 

 Browne, a single example was taken in Leicestershire about 

 the year 1876 ; and the Rev. H. A. Macpherson informs us 

 that a few examples were captured many years ago near Car- 

 lisle, which seems to be the northern limit of its range in 

 Britain. Their presence in Cumberland, writes the observer 

 last mentioned, can only be accounted for on the supposition 

 that they are summer migrants into the district ; the fact that 

 Bats do migrate, either occasionally or periodically, being well 

 ascertained on the testimony of several trustworthy observers. 



Habits. Nearly allied to the Long-eared Bat, the Barbastelle 

 is a species of delicate constitution, and becomes torpid very 

 early in the autumn. It appears early in the evening, and flies 

 higher and more rapidly than the Long-eared Bat. The Indian 

 Barbastelle is remarkable for its habit of squeezing itself into 

 chinks and crevices, which are so narrow as to render it a 

 marvel how the creature gets in. 



Bell states that he has seen a white and also a parti-coloured 

 individual of this species ; while a variety from Warwickshire 

 had, when fresh, the fur of the under-parts tinged with purplish- 

 red or rose-colour.
