The author describes the female generative organs of the 
Tenrec, and the maternal and foetal structures developed in 
utero in connexion with the embryos, and compares them Avith 
those of other Mammals known to him from autopsy or from 
a careful study of the literature on the subject. He believes 
that the modifications of the placental structures form a very 
safe basis for the classification of the Monodelphous Mammalia.
