MAMMALS FROM NEW GUINEA 615 



white above, without darker markings on the metapodials. Tail 

 long, slender, practically naked; scales about 10-12 to the cen- 

 timetre ; colour uniformly pale brown , the few minute hairs 

 white ; prehensile part of tail not very strongly differentiated 

 from rest. 



Skull almost exactly a miniature of that of P. loriae , but 

 the molars, though of similar pattern, are «lecidedly smaller in 

 proportion. 



Dimensions of the two co-types, both males : 



Head and body 119 and 120; tail 169 and 159 ; hind-foot 21 

 and 21.5; ear 14 and 14. 



Skull basal length 27.7; basilar length 25.6; greatest breadth 

 17.6; nasals 10 X 3.5; interorbital breadth 4.6; interparietal 

 3.9 X 8.5; palate length from henselion 14; diastema 9.7; pa- 

 latal foramina 5 X 2.6 ; length of upper molar series 4.8. 



Hab. Haveri. 



A single mutilated specimen from Gerekanumu may also be 

 P. lepidus, but is too imperfect for certain determination. 



This pretty little species is distinguished from all the others 

 by the rich rufous of its body-colour, w^iich contrasts markedly 

 with the sharply defined snowy white of the belly. Like P. loriae 

 and P. mollipilosm it belongs to the less specialized section of 

 the genus, to \n hich I believe the name Pogonomys is specially 

 applicable. 



25. Pogonomys forbesi, Thos. 



26 from Bara Bara, Milne Bay 1 February 1890. 



These specimens are closely similar to the types of this species, 

 obtained by Mr. H. 0. Forbes at Sogere in 1887, if allowance 

 is made for an accidental discoloration of Mr. Forbes's specimens 

 by rust. 



26. Pogonomys lamia, sp. n. 



a-e. Ighibirei (type locality). 

 f-g. Haveri. 



Size small , as in P. lepidus^ but form more squat than in 

 that species. Fur close, soft and woolly. General colour above 

 dull fawn, grizzled with silvery ; centre of face decidedly lighter
