(Plates XXIX.-XXXII.) 



A Norwegian traveller, Dr. Lumholtz, of Christiania, who has 

 now spent four years in Northern Queensland, collecting specimens 

 of natural history for the University of Christiania, has just sent to 

 our Zoological Museum a fine collection of mammals, birds, reptiles, 

 and fishes, besides invertebrates. In giving these short descriptions 

 of a few of the mammals, which I think may be undescribed, I take 

 the opportunity to offer my best thanks to my friend Mr. Oldfield 

 Thomas, for the kind assistance he has given me when examining 

 the skins of the Marsupials in the British Museum, and comparing 

 them with Dr. Lumholtz's specimens. 



1. Phalangista (Pseudochirus) archeri, sp. nov. (Plate 

 XXIX.) 



General characters.- — Male. Mottled yellowish green above, with 

 whitish lines on the back ; lower side white. Tail with short hairs 

 on its apical third. Ears short, rounded, with short hairs. 



Description. — Upper parts a peculiar mixture of yellowish green, 

 white, and grey, the root of the fur bluish grey ; two indistinct 

 stripes of silky white are visible on the back, the tips of their hairs 

 being yellowish ; a short and narrow black line from occiput along 

 the middle of the nape. Lower parts white ; the chin greyish 

 white. Head : snout ashy grey ; a white semilunar spot under the 

 ear, and a small pale yellowish one above and under the eye ; the 

 eyelids are dark brown. Ears short, almost hidden in the fur, 

 greyish externally, bordered with white ; hairs short ; inner surface 

 almost naked. Nose fleshy brown ; the naked area narrow below 

 (3 millim.), the upper lip being haired almost to the central groove. 

 Limbs yellowish grey, the base of the hairs grey like the back ; the 

 fore limbs whitish on inner side. Claws pale yellow. Tail on its 

 first third very thickly clad with woolly hairs, yellowish grey above 

 and underneath, everywhere with interspersed long whitish hairs ; 

 the apical third (short-haired part) whitish ; the naked line on 

 lower surface of moderate length, not reaching half the length of 

 the tail. 



Skull. — Much like the skull of Phalangista albertisii, described 

 by Peters and Doria in Ann. Mus. Genova, vol. xvi. tab. viii. and 

 ix. fig. 2. Ph. archeri differs, however, in having the parietal crests 

 diverging and finally converging, instead of regularly converging, as 

 in Ph. albertisii (if the figures on the plates quoted are correct). 

 In Ph. archeri the profile of the skull seems more oblique in the 

 post-parietal region and the nasal bones to be shorter behind, as in
