Abstract
1.Hipposideros fulvus fulvus breeds once a year in a restricted season. The uterus is bicornuate and is morphologically symmetrical. However, the left side shows a slight physiological dominance over the right side. During each cycle a single young is produced.
2. The foetal membranes at advanced pragnancy are described.
3. The amnion is a thin bilaminar membrane closely adhering to the body of the foetus.
4. The yolk-sac splanchnopleure lies as a collapsed bag near the placental disc. Both endodermal and mesodermal elements undergo hypertrophy.
5. The chorio-allantoic placenta is mesometrial. A deep cleft in the centre of the placental disc separates it into two moieties. The placenta is labyrinthine and vasodichorial.
