LEISLER'S BAT 



From careful observations made by Mr. Moffat in Ireland, as quoted 

 by Major Barrett-Hamilton {A History of "British Mammals), Leisler's Bat 

 does not fly throughout the night, the evening and morning flights 

 lasting a little more than an hour each. 



The voice is sharp and high-pitched. 



THE PIPISTRELLE OR COMMON BAT. 



Pipistrellus pipistrellus, Schreber.

The expanse of wings in this species averages about 8 inches. The ears 

 are rather oval and comparatively narrower than in the Noctule and Leisler's 

 Bat, the tragus barely half the length of the ear and rounded at the tip. 

 The feet small ; teeth thirty-four in number. The colour is usually reddish- 

 brown on the upper parts, a little paler below, but some examples are of a 

 much deeper tint, the darkest I have seen being a dull sooty black. 



The Pipistrelle inhabits the temperate parts of Europe, ranging as far 

 as Kashmir in Asia, and also to North Africa. 



It is more or less plentiful all over the British Islands, in Scotland 

 occurring as far north as the Orkneys and westwards to the Outer 

 Hebrides. Dr. Eagle Clark mentions a pair which he observed at an 

 altitude of 1300 feet at Corrour Lodge, Inverness-shire (Scottish ^}{aturalist, 

 December 1917)- 



It is also plentiful in Ireland. 



This species was considered by Pennant, and others who followed him, 

 to be identical with the common Bat of Continental naturalists, namely 

 the mouse-coloured Bat, Vespertilio murinus, which is a much larger animal 

 and not now recognized to be British. The Rev. L. Jenyns was the
