70 Mr. O. Thomas on 



The only specimen that I obtained was a female, wliicli 

 was captured alive and uninjured. A few days after its 

 capture it gave birth to three naked young. These the 

 mother promptly devoured, and she died three days later. 



This specimen (see PI. IV.), as preserved in formol, is 

 14 inches in length, exclusive of the tail, which measures 

 about 13 inches in length. 



The body and head are covered with sparse coarse hair, 

 which is reddish ferruginous from the eyes to the shoulders 

 and dusky brown on the rest of the body. 



The hair becomes veiy thin and scattered on the hind- 

 quarters, which for some distance on the back and sides are 

 naked, roughly corrugated, and warty, with a sparse, short, 

 ■woolly growth between the excrescences. 



The legs, snout, and eyelids are naked, and, with the bare 

 skin of the rump, are pinkish white. The ears are short, 

 thin, rounded, and are bluish grey with light edges. The 

 heavy rat-like tail is dark brown and naked. The claws are 

 horn-colour. The front feet and claws are large, heavy, and 

 mole-like, and well adapted to digging and tearing asunder 

 rotten wood &c. They are much smaller in proportion than 

 in the Cuban species, however. The snout is also more 

 flexible than in ^. cubunus, from which it also differs in 

 the naked skin of the rump, the colour, size, and other 

 characters. 



XIV. — On Three new Mammals from British New Guinea. 

 By Oldfield Thomas. 



In a further consignment of small mammals presented to the 

 National Museum by Mr. C. A. W. Monckton, Resident in 

 ISorthern British Guinea, there are examples of the two 

 following new Rodents, one of them forming a new and most 

 striking genus allied to Hydromys, but even more highly 

 fcpecialized for an aquatic life. 



The collection also contains specimens referable to Macro- 

 gJo.ssus aiistralis, Pseudochirus cortnnce and Forbesi, and 

 Fhalanyer cartnelitai., all being valuable acquisitions to the 

 Museum. 



In determining the last-named animal, a new Phalanger 

 allied to it has been noticed and is now described. It was 

 obtained by Mr. A. Meek.
