AMNIOGENESIS IN SCHREIBER LONG-FINGERED BAT MINIOPTERUS-SCHREIBERSII-NATALENSIS

Schreiber's long-fingered bat, Miniopterus schreibersii natalensis is seasonally monoestrous, carrying a single foetus in the right uterine horn. Implantation is superficial, the amnion being a pleuramnion. Lat eral folds, originating from the ends of the caudal and cephalic folds , are the main contributors in the formation of the definitive amnion. The formation of the amnion by folding is preceded by the development of a primitive amniotic cavity within the inner cell mass which event ually disappears.
