This formed part of the original Hunterian Collection, and the name " Wha-tapoa-roo " 

 was attached to it, indicating it to have been of the same species as the Phalangista vulpina, 

 originally described by Hunter under the above native name in White's ' Journal of a Voyage

Its dentition agrees with that of the preceding specimen, but it has belonged to an older 

 individual. The cranium is bisected vertically and transversely, through the cellular bases of 

 the zygomata and the tympanic cavities, exposing the otosteals. The falx extends from the 

 roof to the floor of the prosencephalic chamber of the cranium, but has two perforations. The 

 tentorium is exposed in the hinder moiety of the cranium.

 of the junction between the basi- and ali-sphenoid, and terminates above the hinder third of 

 the basisphenoid.
