In this paper the author gives a description of the fœtal membranes and placenta of the Indian Elephant. The chorion forms a transversely oblong sac about 2 feet 6 inches in long diameter, encompassed at its middle part by a placenta of an annular form, 2 feet 6 inches in circumference, from 3 inches to 5 inches in breadth, and from 1 inch to 2 inches in thickness; in structure resembling that of the annular or zonular placenta of the Hyrax and Cat.
