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. 
Pipisirellus pipistrellus, Schreber. 
Plate 3. 
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 plentifial 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 3iaturalist, 
December 191 7). 
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
