FROF. OWEN ON HYPSIPRYMNODON. 



todont suborder *, and must therefore be set aside in the consideration of the affinities 

 of Hypsiprymnodon, a genus which I regard as the type of a distinct group of the 

 Diprotodontia, for which group, from the typical completeness numerically of the toes, 

 the name Pleopodidse t is proposed.

This group is at present represented by a single species, Hypsiprymnodon moschatus, 

 E-amsay, the description of which, unaccompanied by illustration, excited much interest, 

 and a strong desire with the students of the Marsupial order to make a further acquaint- 

 ance with the new form +. 



I have recently been gratified by the reception of skins of mature male and female 

 specimens kindly transmitted to me by the describer of the species, the present accom- 

 plished Curator of the Australian Museum, Sydney. The skull and bones of both fore 

 and hind feet were included in the dried skins ; and these, being extracted, have afforded 

 the materials for the following notes, which, with the accompanying illustrations (Plates 

 LXXI. & LXXIL), may be acceptable to the Society, although they add little to the 

 accurate description in the ' Proceedings of the Linnean Society ' of the capital of one of 

 our most remote and prosperous colonies.
