of the Esk above Penicuik, and one which I succeeded in ~ 
striking down with a walking-stick proved to be of this 
species. In the Edinburgh Museum there are three specimens 
(two adults and a newly-born young one), identified by Mr 
Eagle Clarke (Scottish Naturalist, 1891, p. 92), which were taken 
at The Inch, near Liberton, in July 1880 by Mr T. Speedy, 
who tells me they were found with many others in the hollow 
of an old ash. He assures me there were many dozens 
clustered together in this dormitory, which, however, they 
forsook immediately after its discovery. I have little doubt 
the feeding-ground of the colony was Duddingston Loch, 
over whose surface, on calm summer evenings, numbers of 
V. daubentoni may generally be seen.t On two occasions in 
June of the present year (1891) I was on the south side of 
the loch at dusk, and identified several pairs, their larger size, 
and habit of gliding in easy circles close to the surface of the 
water, serving at once to distinguish them from the Pipi- 
strelles. In other suitable localities I have from time to time 
seen bats that doubtless were of this species. In the Pro- 
ceedings of the Berwickshire Naturalists’ Club (vol. ix., p. 441), 
Dr Hardy states—on the authority, he tells me, of the late 
Mr Robert Gray—that Daubenton’s Bat is well known about 
Dunbar, a district from which, through the attention of Mr 
G. Pow, I have received three examples in the flesh. Two of 
these—male and female—were shot as they flew over a sheet 
of water at Broxmouth on 20th June of the present year 
(1891), and the third by the Tyne at East Linton four days 
later. The expanse of the wings in the first of these was about 
9? inches, while in the last it was barely 9. The species has 
likewise been recorded more than once from Roxburghshire 
(Proc. Berw. Nat. Club, ix., p. 441; and Scottish Leader of 22nd 
June 1888). Its Scottish stronghold, however, would appear 
to be in the neighbourhood of Dumfries, where Mr Service 
tells me it is commoner than the Pipistrelle. As in the case 
of other Bats, July seems to be the usual time for the pro- 
duction of the young. 
1 Vogt, in his Natural History of Animals (London, 1887, vol. i., p. 106), 
says of this Bat, ‘‘Its winter quarters are in hollow trees, often pretty far 
from its hunting-ground,”
