very minute gnats, while resting on the outer leaves, or when about 
to settle on them. 
If watched very closely for a little time, they move on to some 
other tree, appearing to shun observation very carefully. 
Gilbert White, I think, remarked of the Noctule, that it usually 
came abroad later than the Pipistrelle, which I can from personal 
experience affirm to be the case. The species now under considera- 
tion is even later than the Noctule, seldom being seen until the latter 
has been abroad for an hour; so late that, excepting on very clear 
evenings, there is little chance of either observing or obtaining spe- 
cimens. 
It is probable that they may be seen during the greater part of the 
summer months, for I remember to have seen and particularly no- 
ticed them for a long time before I thought of shooting one, and also 
for a considerable length of time afterwards. ‘They may at any time 
be known by a person at all conversant with the method of flight of 
the different species of Bats, by their unsubstantial, butterfly-like 
appearance. 
Both the specimens which came into my possession in the way 
alluded to were females, and on dissection contained a single foetus, 
about half an inch in length; yet even at this early age the mem- 
branes were considerably developed, and all the parts bore nearly 
the same relative proportion to each other as in the adult. 
The auricle of the ear appeared to be nearly, if not quite fully 
formed, and folded forward over the eyes, reaching almost to the end 
of the nose. 
When skinned and dissected this Bat was quite free from all un- 
pleasant smell.

Since the specimen obtained by Brongniart in the neighbourhood 
of Dover, none are recorded as having occurred till the present time, 
with the exception of a single specimen mentioned by Professor Mac- 
Gillivray, from Winchester, and described by him in the ‘ Naturalists’ 
Library,’ vol. xvii. He there states that the ears have ‘‘a semi-
