24 PSEUDOCHIRUS CAUDIVOLVULUS. 



11. Adult male. Van Dieraenslaud. Less dark colored 

 than No. 10. 



12. Not fullgrown female. Van Diemensland. Frank, 

 1845. Colored like N». 11, but legs and circle round the 

 eyes browner. 



13. Adult male. Van Diemensland. Presented by the 

 Sydney-Museum, 1881. Colored like N». 10, but under- 

 parts of head and body and inside of legs greyish white , 

 the base of the hairs being of a slate color. 



There are seven skulls of this species in our Museum. 



Since I wrote my paper »on the species of the Phalan- 

 ger-genus Pseudochirus" (Notes from the Leyden Museum, 

 1884, p. 108) W. Collett published (^Proc. Zool. Soc. Lon- 

 don, 1884, p. 381) a paper »on some apparently new Mar- 

 supials from Queensland, collected by D^". Lumholtz." M^ 

 Collett describes three new species of the Phalangista-grou^ , 

 one belonging tho the genus Pseudochirus ^ Ps. Archeri, 

 another being , according to the author , a true Phcda7igista , 

 Ph. Herhertensis y meanwhile the third should be the type 

 of the new genus Hemibelideus , H. lemuroides. Notwith- 

 standing the fine figures of the animals and of their skulls it 

 is very difficult to get a good idea of the species , as the 

 descriptions are somewhat confuse and not always agree 

 with the figures. As to the measurements the author al- 

 ways gives the length of the body (with or without the 

 head?). Ph. Archeri belongs to the Pseudochirus-genns 

 according to M"^. Collett, but either in the figure nor 

 in the description I can find any reason to believe that 

 the character of Pseudochirus (the two inner toes of 

 the fore foot separated from and partially opposable 

 to, the other three) is really present. The female of Ph. 

 Herbertensis shows in the figure this peculiarity and , if 

 this figure is correctly drawn , Ph. Herbertensis too may 

 belong to the Pseudochirus-genus and differs still less from 

 Ph. viverrina Ogilby {Pseudochirus caudivolvulus) than M"", 

 Collett believes: in the description of Ph. Herbertensis he 

 does not mention this peculiarity of the fore feet; and
