186 ON THE NEW-GUINEA MAMMALS. 



135 mm., tail 137 mm. Based upon a female, collected 

 by Mr. Stalker on the Gira-river, British New-Guinea 

 (Ann. Mag. Nat. Hist. 1904, p. 202). 



65. Uromys gracilis Thomas. 



A medium-sized animal with a long tail and narrow 

 skull; readily distinguishable from its nearest ally, U. 

 Stalkeri^ with which it agrees in colour, by its longer tail 

 and markedly narrower interorbitai region. Head and body 

 about 140 mm., tail 175 mm. The species is based upon 

 two specimens, collected by Meek at Owgarra, Angabunga- 

 river, S. E. New-Guinea (Ann. Mag. Nat. Hist. 1906, 

 p. 328). 



QQ. Uromys rufescens Alston. 



The type-specimen is from Duke-of- York-island and des- 

 cribed by Alston in P. Z. S. L. 1877; in the very year 

 1877 described under the name musavora by Ramsay from 

 the same island. It is most allied to Uromys Bruynii, but 

 a third smaller, more uniformly rufous in colour and the 

 tail, 107 mm., markedly shorter than head and body (125 

 mm.). In the Leyden-Museum there are three specimens 

 from Sorong, W. N. G., collected by Dr. Bernstein in 1859. 



67. Uromys papuanus Meyer. 



Dr. A. B. Meyer discovered in May 1873 a to Uromys 

 aruejisis Gray (Aru-islands) closely allied species, on New- 

 Guinea, near Rubi, the south point of Geelvink-Bay, 

 and called it Uromys papuanus. No further description 

 exists, as far as I am aware (Ann. Mag. N. H. 1876, 

 p. 146).
