616 OLDFIELD THOMAS 



tlkan back , the eyes surrounded by a blackish rim ; a lighter 

 patch behind base of ears. Undersurface pure white or yellowish 

 white throughout. Hands and feet white, the metapodials not 

 darker. Tail rather coarsely scaled, more hairy than in P. loriae 

 and lepidus^ though still not more thickly haired than in an 

 average Mus; its colour pale brown throughout ; smooth prehen- 

 sile portion on the upper side of the tip markedly distinct from 

 the scaly and hairy remainder. 



Skull short and broad, with a very short muzzle, and very 

 abruptly expanded zygomata ; interorbital region narrow , con- 

 cave above, sharply edged. Molars small, their pattern as in the 

 highly specialized " Chiriiromys " group, typified by P. forhesi. 



Dimensions of the two co-types , male and female : 



Head and body 111 and 118; tail 161 and 158; hind-foot 

 24 and 25 ; ear 17 and 17.5. 



Skull {d^) basal length 28; basilar length 25.5; greatest 

 breadth 20; nasals 10.3 X 3.8; interorbital breadth 4.8; inter- 

 parietal 3.7 X 9.3; palate length from henselion 13.5; diastema 

 9 ; palatal foramina 4.2 X 1-8; length of upper molars series 4.7. 



Typical locality. Ighibirei. 



P. lamia belongs to the '' Chiruromys " section of the genus, 

 with more complicated teeth, such as were figured in the ori- 

 ginal description of P. forhesi, and with the tail rather more 

 hairy, and more markedly speciaHzed for prehension. From the 

 other species of this section , P. forbesi and P. pulcher^ it is 

 readily distinguishable by its much smaller size, while from 

 P. lepidus, similar in size, it is separated not only by the im- 

 portant sectional characters, but also by its grizzled fawn, instead 

 of rufous colour. 



The two Haveri specimens are quite similar to those from 

 Ighibirei, the typical locality.
