68 PTEEOPODID^. 



Skull and dentition veiy similar to that of Ft. niedius (which this 

 species also resembles in the general colour of the fur), but the back 

 teeth are larger. Upper incisors well developed, close together, and 

 equal ; in one specimen (in the Leyden Museum) the outer upper 

 incisors on each side are broader and shorter than the inner incisors 

 and bifid ; inner lower incisors separated by a narrow space, about 

 one third the size of the outer incisors ; no trace of the first upper 

 premolar ; last molar about equal to the last lower molar, which 

 again is nearly equal to the first lower premolar, which occupies the 

 centre of the space between the canine and second premolar ; the 

 antepenultimate upper molar is narrow, but considerably exceeds in 

 antero-posterior diameter the preceding molar ; the last upper molar 

 has an almost circular crown, and is placed towards the inner side 

 of the tooth-row. 



Postorbital process very long, nearly meeting the weU-developed 

 corresponding process from the zygoma. 



Length (of the type specimen), forearm 4""7, thtmib 2"-], second 

 finger 3"-4 ; third finger — metacarp. 3"'2, 1st ph. 2"-35, 2nd ph. 

 3"-45; fifth finger— metacarp. 3"-l, 1st ph. l"-35, 2nd ph. l"-25 ; 

 tibia 2", foot l"-7. 



Length (of an adult 2 from Philippine Islands), head and body 

 7""5, head 2"-6, ear 0"-95, eye from tip of nostril 1", forearm 5"-4, 

 thumb 2", second finger 3"-7 ; third finger — metacarp. 3"-4, 1st ph. 

 2"-6, 2nd ph. 4"-l ; fifth finger— metacarp. 3"-7, 1st ph. l"-55, 2nd 

 ph. l"-65; tibia 2"-15, foot l"-8.

This species resembles Pt. medius in the colour of the fur pro- 

 bably more closely than any other species except Pt. edwardsii from 

 Madagascar, but is at once distinguished by the differently shaped 

 and much shorter ears and by its conspicuously smaller size. The 

 premolar and molar teeth are much broader and altogether larger, 

 and the last upper molar is placed towards the inner side of the 

 tooth-row.
