[ReceiTed June 5, 1896.] 



The specimen from which the following notes were made was 

 kindly placed at my disposal by Mr. F. E. Beddard, the Society's 

 Prosector. I have been struck by the fact that of late years the 

 MacropodidsB have not received nearly so much attention as the other 

 members of the Marsupial order, and for this reason I have thought 

 it worth while making a fairly exhaustive dissection of Petrojale, 

 laying special stress on the vascular, nervous, muscular, and 

 ligamentous systems, and comparing them with the accounts of 

 other writers to which I have had access. The other systems, 

 which are already well known, I have passed over more rapidly, 

 though 1 am fully alive to the importance of basing our knowledge 

 of the anatomy of any animal on several dissections by different 

 observers.
