408 ME. OLDFIELD THOMAS ON MAMMALS 



Carpomys ph.eurus Thos. (Plate XXXIV. fig. 1.) 

 a-c. 3 ad. sks., d ? . Monte Data, 7000-8000 feet, Feb. 1895. 



Size rather less than in C. melanurus. Quality of fur and general colour almost 

 exactly as in that species. Ears rather smaller, less thickly hairy, and not prominently 

 black. Belly-hairs dull buffy white to their roots, not slaty basally. Tail with the 

 body-fur not extending on to its base more than in ordinary Rats, more thinly haired 

 than in C. melanurus, so that the scales, which are very small, running about 13 to the 

 centimetre, are visible through the hairs ; in colour it is uniformly dark brown, 

 occasionally approaching black, but never the deep shining black of C. melanurus. 



Skull (PI. XXXVI. fig. 7), as compared with that of C. melanurus, with the nasals 

 less expanded anteriorly and less abruptly tapering posteriorly. Interorbital space 

 comparatively broad and parallel-sided, the rudimentary ridges not approaching each 

 other on the top. Palatal foramina pointed in front, gradually broadening backward. 

 Palate ending opposite to front of m. 3 . 



Teeth light and delicate. Incisors comparatively narrow. Molars, in marked 

 contrast to those of C. melanurus, quite small in proportion to the size of the animal, 

 but of the same essential structure. 



Dimensions of the type, an adult male in skin : — 



Head and body (stretched) 195 millim. ; tail 178 ; hind foot (moistened) 31. 



Skull, see p. 404. 



Type. B.M. 95. 8. 2. 14. 



" The brown-tailed Carpomys was somewhat rare on Monte Data. The Igorrotes 

 used to hunt for the various Eats on Monte Data in small parties accompanied by their 

 dogs, and spent most of the day at this — to them — carious occupation. The animals 

 that I saw captured were dug out from among the roots of trees by the aid of spears 

 and choppers. The flat table-top of Monte Data is much burrowed by various species 

 of Rodents ; the Igorrotes, unlike the Kina Balu Dusans, not trapping Rats for their 

 food.

Crateromys. 

 Crateromys Thos. Ami. Mag. N. H. (6) xvi. p. 163 (1895), 



Size very large; general form not unlike that of Pliloeomys. Claws smaller and tail 

 bushier than in that genus. 



Skull, in a very general way, not unlike that of a gigantic Neotoma, strikingly 

 different from that of Phloeomys. Muzzle slender. Zygomata squarely and boldly 

 expanded. Interorbital region narrow, narrowing backward, edged with distinct but 

 not exaggerated ridges, which pass backward on to the parietal and interparietal 

 bones, and show no tendency to overhang the temporal fossae. Interparietal large.
