216 On some new Species of Uromys. 



distinct U. banjieldi, de Vis, of Dunk Island, N. Queensland, 

 Lave the skull markedly longer than in U. melicus. 



Uromys lutillus, sp. n. 



A small species with buffy-greyish under surface. 



Size much smaller than in any of the described species. 

 General colour above dark clay-colour or dull fulvous. 

 Under surface similar but paler, the hairs slaty at base, buffy 

 terminally ; throat, axillary region, and centre of belly with 

 some ill-defined whitish patches, a large white patch covering 

 the inguinal region. Hands and feet whitish. Tail uni- 

 formly brown ; hairs very few; scale-rings about fifteen to 

 the centimetre. 



Skull with square unbeaded supraorbital edges. Palatal 

 foramina unusually long, reaching back to the level of the 

 front of to 1 . 



Dimensions of the type (measured in skin) : — 



Head and body (c.) 112 mm. ; tail 115; hind foot 24. 



Skull : greatest length (c.) 29 ; condylo-incisive length (c.) 

 27; tip of nasals to lambda 25*7; zygomatic breadth 15*2; 

 nasals 10'3 ; interorbital breadth 4*3 ; palatilar length 12*7 ; 

 palatal foramina 5'1 ; upper molar series 5'3. 



Hah. Owgarra, Angabunga R., S.E. British New Guinea. 



Type. Adult male. B.M. no. 5. 11. 28. 20. Original 

 number 20. Collected 3rd November, 1904, by A. S. Meek. 

 Two specimens. 



This Uromys is distinguished from all previously described 

 species by its small size, and from the two next following by 

 its long palatal foramina, comparatively large teeth, and 

 buffy-grey underside. 



Uromys murinus, sp. n. 



A small insular species with white belly. 



Size quite small, about as in U. lutillus. General colour 

 above strong fulvous, but both the specimens have been 

 skinned out of alcohol and are probably discoloured. Under 

 surface white, the white narrowed on the belly. Hands and 

 feet white. Tail of normal proportions, brown above, slightly 

 paler below, its hairs few and short ; scale-rings fourteen to 

 the centimetre. 



Skull with the supraorbital edges sharply square, not 

 ridged. Palatal foramina of medium length, not quite 

 reaching to the level of the front angle of m 1 . Molars as 

 long as, but rather narrower than, in U. lutillus^ decidedly 

 larger than in the next species.
