SUMMARY. One hundred and eighty‐five common bats ( Pipistrellus pipistrellus ) were collected during June and July from two cottages near Clovenfords, Selkirkshire. Most of them were pregnant or lactating females, and their examination has provided fresh data on the length of gestation, the distribution of pregnancies between the two horns of the uterus, and other points of interest in connection with the reproductive cycle.
