The author confirms the statements of Owen, Chapman, and others as to 
the yelk-sac in the Marsupials performing the functions of the allantois 
in the Placentalia , and in addition he has discovered that nourishment is 
conveyed to the foetus by means of vascular villi placed on the outer 
surface of the subzonal membrane, over the attached portion of the yelk- 
sac.

The author believes that the humerus referred by Prof. Owen to 
Nototherium did not belong to it, and that a bone now described from 
the Darling Downs is really the humerus of that animal.
