Diaijnosis. — Rostrum broad, nearly parallel-margined, orbits 

 small, sagittal crest low or incomplete, coronoid process low and 

 sloping. Ciiigulum of canines and upper incisors nnusually broad, 

 \\ large, posteiior ledges of p\ p^, and p, strong, p^ p', p^, and p^ 

 with distinct antero-internal basal ledges. Ears moderate, tibia 

 naked above. Back dark brown, mantle varying from buffy to 

 deep tawny ; a buffy pectoral patch contrasting with dark brown 

 belly and sides of breast. Size small : forearm 101-106 mm. 

 Hah. Ruck group. Central Carolines. 



Skull. — Brain-case moderately deliected, alveola.' line if continued 

 posteriorly passing very nearly through upjier point of occipital 

 cond5de. Rostrum broad and low, lateral margins viewed i'rom 

 above only slightly converging anteriorly (subparallel) ; width of 

 rostrum across alveolar borders of p^-p' (10 mm.) much greater 

 than depth at middle of p* (S-8-3mm.). Orbits small, diameter 

 (9-9"2 mm.) less than width of rostrum across p'-p' (10 mm,); 

 front of orbit above or very slightly in front of middle of m'. 

 Postorbital processes thin, reaching little more than half the 

 distance from frontal to zygoma : corresponding processes on 

 zygoma undeveloped ; distance from tip of postorbital process to 

 gnathion greater than from former point to lambda: frontal 

 region between bases of postoi'bital processes nearly flat. Temporal 

 ridges in one adult skull, of three examined, rather closely 

 approximated, but not fused in median line ; in two adult skulls 

 fused and forming a low sagittal crest in frontal and interparietal, 

 but slightly separated in parietal region. Coronoid process low, 

 narrow antero-posteriorly, and vloping ; coronoid height of mandible 

 subequal to length of ujjper tooth-row, c-m", much less than c-m^ ; 

 condyles not much above level of alveolar lino, this latter projected 

 backward nearly lunching lower margin of condyle.
