Attention may also be drawn to Winge's severance of the 

 -crescent -toothed or subselenodont Phalangers {Pseudochirus and 

 Petau7'oicles) from the rest as representing a special subfamily 

 Pseudochirini equivalent to the' Phalangerinte containing not 

 only the rest of the genera Thomas assigned to that subfamily, 

 but all of those constituting the family Macropodidfe of that 

 author. 



Max Weber (Die Siiug. p. 348, 1904) followed Winge in 

 admitting the two families Phalangeridte and Phascolarctidte as 

 he defined them ; but he did not admit the subfamily groups 

 Phascolarctinae and PhascolomyinsB for Phascolarctos and Phasco- 

 ■lomys respectively, and in the case of the Phalangeridse he made 

 a compromise between Thomas's and Winge's systems by dividing 

 the family into three subfamilies : Phalangerinae, Hypsiprymno- 

 dontinae, and Macropodinpe. 



It will be noticed that neither Winge nor Max Weber attaches 

 any particular importance to the structural peculiarities of
