PSEUDOCHIRUS. 109 



In the above quoted work Gould adds a new species, 

 Pseudochirus lanuginosus , from het Upper Hunter , Dart- 

 book District. He says: „while in the country I had no 

 difficulty in distinguishing them (viz : cookii and lanuc/i- 

 nosus), and never had a doubt of their being distinct; 

 but what was plain to me in Australia , 1 am unable 

 to render so clear to the Mammalogists of Europe," and 

 further on „I may remark that there is a greater diffe- 

 rence between the P. lanuginosus and cookii, than there 

 is between P. cookii aiid fuliginosus''' (this must be a mis- 

 take ; one should read viverrinus , as fuliginosus belongs 

 to quite another genus). My opinion is that we have here 

 to do with another mere variation in color, and conse- 

 quently that Ps. lanuginosus is synonymous with Ps. 

 cookii. 



The large and broad ears and the slender tail, which is 

 constantly white at the apex, distinguish Pseudochirus 

 cookii at first sight from the other species of the genus. 

 The skull in its principal parts agrees with the skull of 

 Ps. albertisii , but the muzzle is broader, the nasalia are 

 more elongated , the upper incisors are smaller and the 

 lower incisors are otherwise shaped than in that species 

 and agree uiore with the same parts in Ps. bernsteinii. 



Pseudochirus bernsteinii Schlegel (1866) from Salawatti, 

 has been collected by d'Albertis in New Guinea (1872). 

 Compared with Ps. albertisii it is of a smaller size, the 

 fur is shorter and less woolly and a dark brown line or- 

 nates the middle of the head and a ditto patch the base 

 of the ears; the peculiar shape of the skull and the weak- 

 ness of the dentition (see Schlegel , Nederlandsch Tijd- 

 schrift voor de Dierkunde. HI, p. 358) distinguish this 

 species from the other PseifC^oc/wVws-species. 



Pseudochirus albertisii Peters (1874) from the Arfak- 

 mountains, New Guinea, is stouter in all proportions than 

 the foregoing species, the ears are shorter and more hairy, 

 the fur is longer and more woolly and a broad dark line 

 runs along the spine of the back (there is no trace of a line
