Diagnosis. — Allied to Pt. samoensis, which ib resembles in most 

 cranial and dental characters (short rostrum, large i^ and pj, verj- 

 strong posterior ledges of cheek-teeth), but with posterior ledge of 

 p^, m^, and m, extending forward on lingual face of tooth as a 

 broad, well-defined shelf. Externally (fur, colour) much like 

 Pt. dasymallus. Size below medium : forearm 123'o-130 mm. 

 Ifab. Aneiteum, New Hebrides. 



SJcull (fig. 14). — General shape as in Pt. nawaiensis and samoensis ; 

 size as nawaiensis, smaller than samoensis. — Deflection of brain- 

 case moderate, alveolar line if projected backward passing through 

 middle or upper half of occipital condyles. Rostrum very short, 

 still a little shorter than in Pt. samoensis, stout ; length from front 

 of orbit to tip of nasals subequal to (rather less than) three-fourths 

 the width of the brain-case at root of zygomata ; width of rostrum 

 externally across alveolar borders of p'-p' subequal to orbital 

 diameter ; front of orbit vertically above middle of p''. Size of 

 orbits as in the allied species. Sagittal crest well developed. 

 Zygomatic arch unusually deep (vertical extent); iu none of the 

 skulls examined (eight) any trace of postorbital processes on 

 zygomatic arch. Coronoid process extremely high, its front margin 

 steeply ascending; coronoid height of mandible much more than 

 length of lower tooth-row, c-mj. 



Teeth(6g. 14). — Chief characters: see diagnosis of species.— Upper 

 incisors as in Pt. samoensis. Upper canines short, stout, recurved ; 

 inner cingulum very strong, forming a broad shelf with raised 

 margin, the latter in most specimens simple, in others indistinctly 

 subdivided into a series of small rounded tubercles. p^ as in 

 Pt. nawaiensis and samoensis, less reduced than usual, sometimes 

 terete, but generally with crown rather distinctly differentiated 

 from shaft, present in all skulls (eight) examined, none of which 



* Spelt aneifeamis by most of the authors referred to above, by one (Troues- 

 sai-t, 1897, 1904) aneitanvs, and by two (Matschie, Miller) anetianus. The 

 latter is the earliest (Gray, 1870), and technically therefore only admissible, 

 form of the name.
