184 ON THE NEW-GUINEA MAMMALS. 



one, while in depth the lower teeth exceed the upper by 

 a third. Head and body measure 30 cm., tail 32 cm. 

 Externally it can only be distinguished from large Papuan 

 ZJromï/s-species by its darker colour and its slightly hairy 

 tail (Thomas, Ann. Mag. N. H. 1903, p. 200). 



59. Uromys validus Peters et Doria. 



The genus Uromys has been created by Peters in 1867 

 for the reception of mice characterized by "dickern poly- 

 gonalen, nicht in so regelmassigen Ringeln stehenden 

 und nicht sich deckenden Schwanzschuppen". Uromys 

 validus-STpecimens have been collected by d'Albertis at 

 Katau, S. E. New-Guinea; other ones from Loria's col- 

 lections are from Haveri, near Mount Wori-Wori and from 

 Kapa Kapa and Aroma, east from the mouth of the Kemp 

 Welch-river. Probably not distinct from Uromys macro- 

 pus Gray, said Thomas (Ann. Mus. Genova, 1897, p. 616). 

 Head and body 20 cm., tail 20 cm. 



60. uromys Bruynii Peters et Doria. 



Type-specimens from Salawattie described in 1876 by 

 Peters and Doria; collected by d'Albertis on the Yule- 

 island and at the Fly-river, and by Loria everywhere be- 

 tween the Owen Stanley Range and the sea, in or near the 

 watershed of the Kemp Welch-river. There seems to be an 

 extraordinary variability of this animal in size, according 

 to Thomas, varying between 9 to 16 cm. The same 

 author remarked that it is possible that the name Bruynii 

 will ultimately have to give way to cervinipes^ Gould's 

 Mus cervinipes being a member of this group (Ann. Mus, 

 Genova, 1897, p. 617). 



61. Uromys levipes Thomas. 



Collected by Loria at Haveri, near Mount Wori-Wori, 

 and at Gerekanumu, on the southern slope of the Astro-
