Introductory. 



This paper continues the subject treated of in a previous 

 communication, (Linn. Soc, N.S.W., YoL vi., p. 796) and gives 

 some account of the organs of sixty kangaroos obtained during this 

 year. My attention has been directed chiefly to the question of 

 the presence or absence of a direct communication between the 

 median portion of the vagina and the urogenital canal, but some 

 of the more salient characters of these two chambers have been 

 noted, especially of such as previous accounts have made but 

 slight mention, or as in the case of species in which the urogenital 

 organs have been hitherto undescribed. 



The results arrived at are : — 



(1.) Corroborative of the post part urn existence of the direct 



communication in some species, in which this condition 



has already been met -with. 



(2.) Descriptive of the post partiim existence of the direct 

 communication in ten females belonging to two species 

 {TIahiiaturiis dorsalls and Onijclwgalea frcdiiata) of which 

 the urogenital organs have hitherto been undescribed. 



(3.) Corroborative of the anomalous condition prevalent in 

 Macwpus major, 



(4.) Descriptive of the conditions presented by a series of 

 unimpregnated specimens. 



Of my sixty specimens, forty-four were from animals which 

 had certamly produced young, while the remaining sixteen form
