12 Whitaker: Notes on the Habits of Bats. 
back of one of the side trees. They woke up quicky when the 
light of our candles shone upon them, and began to drop off 
and fly about, re-assembling from time to time in smaller 
clusters in different parts of the roof. I procured twenty-two 
specimens for examination and found these consisted of eleven 
males and eleven females. The average wing expanse of the 
eleven males was 9.33 inches and of the females 9.56 inches. 
This confirms my opinion that in the case of the Long-eared 
Bat, (and probably some other species also), the female is 
usually larger than the male. 
On Plate III., Fig. 2, is a picture of an old oak tree on the 
Stainbrough estate, in which a colony of Leisler’s bats have 
made their home. The small x to the left of the main trunk, 
and fairly high in the picture, indicates the position of the den, 
which is in a long slit in the dead stump of a broken branch 
immediately above it. On Plate II., Fig. 2, four Long- 
eared Bats are shown disturbed by the removal of a large piece 
of loose bark under which they were clinging. Fig. 3 is a 
typical ‘cluster’ of long-eared bats clinging to an old wall. 
Many of he bats in the centre are quite buried by others which 
are clustered over them. In the group shown there were 22 
bats. Plate III., Fig. 2, is from a photograph taken by Mr. 
E. H. Wakefield. 
On plate Plate II., Fig. 1, is a twilight haunt of Natterer’s 
Bat, the place where the two specimens referred to above 
were obtained. Plate III., Fig. 1, shows the cottage in- 
habited by the colony of Pipistrelles. The position of the exit 
hole is marked by a small x immediately beneath it, and near the 
apex of the gable. 
The difficulty of solving many interesting points relating 
to the distribution and relative abundance of different species 
of bats lies chiefly in the meagreness of the data available. 
May I remark here that I shall be exceedingly grateful to any 
reader who will, at any future time, forward to me any specimen, 
either alive or dead, which may happen to fall in his way. 
These I should be pleased to name and immediately return or 
liberate as desired. The fullest possible particulars relating 
to date and place of capture should accompany any specimens 
sent, which should be addressed to me at Kingwell, Worsboro’ 
Dale, Barnsley.

On the suggestion of Mr. Mark Sykes, M.P., Sir Tatton Sykes has 
kindly sent for exhibition in the Hull Museum the objects of pre-historic 
date in his possession. These include the contents of the famous Duggleby 
Howe burial mound, which contained flint and bone weapons and im- 
plements of exceptional interest ; a pre-historic jet necklace containing 
several hundred beads; a fine series of pre-historic implements in flint, 
sandstone, bronze, etc., and some earthenware vases taken from British 
burials on the Yorkshire Wolds.
