162 THE ZOOLOGIST. 
of Sand Martins, over the surface of the river near the bridge in 
the town, never appearing to rise very high in the air, and seldom 
flying much beyond the river-banks. He adds (Zool. 1874, pp. 
4127, 4128) that in April, 1856, he obtained this species from the 
Isle of Purbeck, and in July, 1863, from Ulleswater, where (as well 
as at Grasmere) they do not fly till late at night over the lakes, 
but in the boat-houses they fly by day. He has also seen 
specimens taken at Preston, near Brighton, a locality in which 
he would not have expected them, as they appear to be especially 
addicted to water, and there is none there. Before quitting the 
Isle of Purbeck, it may be well to note another locality for this 
Bat in the same county of Dorset, namely, Glanville’s Wootton, 
where Mr. J. C. Dale, in his account of the local fauna, states 
that it is abundant. From the Isle of Wight it has been reported 
by the Rev. C. A. Bury, and it is probably the species referred 
to by Mr. W. P. Cocks, under the name Vespertilio emarginatus, 
as not uncommon in the neighbourhood of Falmouth, V. emar- 
ginatus of Jenyns being identical with V. daubentonit of Leisler 
and Kuhl, but not with V. emarginatus of Geottroy, a continental 
species (with a longer, more pointed, and more deeply emarginate 
ear) which has not yet been found here. Amongst other localities 
for V. daubentonit Bell gives Milton Park, near Peterborough, 
and even mentions its occurrence in London, at Islington, whence 
three examples were procured by Yarrell. To these may be 
added another locality near London, namely, Kingsbury Reservoir, 
where we have seen it ilying over the water near the Hyde bridge, 
and where, to identify the species, we shot one about seven o'clock 
one evening in August, 1867. Another, in the collection of 
Mr. Bond, was found clinging to the wall at the head of this 
same reservoir one cold wet day in summer. On turning to an 
old note-book of that date we find the following entry :— 
“ Daubenton’s Bat seen at the Hyde bridge on the Brent several 
times. Frequents stagnant water. Flies very late; is slower on 
the wing than most of the other Bats. Wings more pointed, and 
does not turn and twist like many, but skims like a Sand Martin 
over the water.” This peculiarity seems to have struck most 
people who have had an opportunity of obtaining it alive. 
Mr. Tomes, writing in 1874 of its habits, as observed by him in 
Warwickshire, says :—‘ So peculiar are the vespertinal habits of 
this species that, while very abundant, an ordinary observer might
