Placental scars were recorded in the uteri of forty-four non-pregnant mature elephants. Some 159 scars were observed averaging 3·6/female (range 1 to 9). They were almost equally distributed between the right and left cornua, and the distribution of implantation sites is illustrated. The relation between estimated ages of the elephants and the number of placental scars they show indicates a mean calving interval of about 4 years but there is evidence that the calving interval has increased in recent years.
