Diacjnosis. — Brain-case slightly more deflected than usual ; orbits 

 large ; sagittal crest low or undeveloped ; coronoid process low and 

 sloping. Cingulum of canines narrow ; cheek-teeth shorter, but 

 scarcely narrower than usual ; upper jn'cmolars subsquarish ; 

 posterior ledges of premolars obsolete, except postero-internally in 

 p*. Ears long and pointed ; tibia naked above. Blackish above 

 and beneath, with strongly contrasting huffy mantle; glandular 

 neck-tufts in males. Forearm 13G-141 mm. Bah. British New 

 Guinea. 



Sl-ull (fig. 17). — Deflection of brain-case greater than usual, 

 alveolar line if projected backward passing through supraoccipital 

 above upper margin of occipital foramen. Kostrum low, somewhat 

 compressed laterally ; width of rostrum across alveolar borders of 

 p'-p' subequal to depth at middle of p\ Orbits large, diameter 

 (14-I4'2mm.) much more than width of rostrum at p' (11-12 mm.); 

 front of orbit above front of m', Postorbital processes long, reaching 

 within short distance of corresponding processes of zygoma; distance 

 from tip of postorbital process to gnathion much more than from 

 former point to lambda ; frontal region between postorbital pro- 

 cesses flatly concave. Temporal ridges in adult individuals closely 

 a])proximated or united into a very low sagittal crest. Coronoid 

 process low, narrow antero-posteriorly, and sloping ; coronoid height 

 of mandible subequal to length of upper tooth-row, c-m", much 

 less than c-m, ; condyle somewhat above alveolar line, which 

 projected backward passes a little below, or nearly touches, lower 

 margin of condyle. 



Teeth (fig. 17). — Upper incisors typical Pteropine, slightly spaced, 

 i.^ once and a half to twice the bulk of i^. Cingulum of canines 

 narrow ; profile of front margin of upper canines slightly convex 

 or nearly straight, of lower canines more convex ; vertical groove 

 on front face of upper canines deep, terminating above tip of tooth, 

 p' spiculiform. Pj slightly larger than i., and m.^, smaller than m*. 

 p^ and p* shorter than usual, basal outline subsquarish with rounded 

 corners; posterior basal ledge obsolete in p', in p^ developed only 

 at postero-internal corner of tooth, forming a distinct rounded 

 tubercle behind inner main cusp of tooth ; antero-internal base 

 (cingulum) of p* rather more developed than usual, forming a low, 

 projecting, but incompletely differentiated ledge in front of inner 

 main cusp; some trace of a similar antero-internal ledge detectable 

 also in m'. m'- slightly larger than p,. Posterior basal ledges 

 undeveloped in lower check-teeth. 



Palate-ruhjes. — 5-f-4-|-2. First ridge terminating laterally at 

 front of canine ; secoud at back of canine ; third at front of p' ;
