5. On the Anatomy of Petrogale xanthopus, compared with 
that of other Kangaroos. By F.G. Parsons, F.R.C.S., 
F.Z.S., F.L.S., Lecturer on Comparative Anatomy at 
St. Thomas’s Hospital. 
[Received 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. Ihave been struck by the fact that of late years the 
Macropodide 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 Petrogale, 
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 I am fully alive to the importance of basing our knowledge 
of the anatomy of any animal on several dissections by different 
observers.
