These were all captured in an old ruin not far from the sea, and, along with a dozen or so more, were taken from a hole in the masonry formerly occupied by Jackdaws. The collection consisted of both old and young, and nearly all have been most carefully preserved.
The occurrence of this comparatively rare British Bat in such large numbers is most interesting, and especially so because the young are of almost all ages—some so very juvenile as to be hardly capable of spreading their membranes.
