Diarj)wsis.—'Ro&tTi\m short aud broad, coronoid high, i , p' 

 and p, larger than usual, posterior basal ledges of p\°p and p' 

 strong. Tibia thickly clothed above. Colour of fur dark brownish 

 above and beneath, lightened with huffy or wood-brown tips to the 

 hairs, but very variable, according to greater or less predominance 

 ot dark brown or buffy (wood-brown) element; mantle and crown 

 bufty or tawny ; face mixed blackish, greyish, and buffy. Size below 

 medium : forearm 124-131-5 mm. Hah. Fiji Is. 



/S^-M«.— Eostrum short and stout ; length from front of orbit to tip 

 ot muzzle much less than width of brain-case at root of zygomata, 

 only a little more than maxillary width externally across m'-m' • 

 front oi orbit vertically above back of p^ or front of m'. Sa'^ittal 

 crest well developed. Postorbital processes long and slender 

 extending two-thirds or three-fourths the distance from frontal to 

 zygoma ; corresponding processes of zvgoma small or undeveloped 

 Coronoid process of mandible high, coronoid height larger than or 

 equal to length of lower tooth-row, c-m^. 



Tee/A.— Chief characters: see diagnosis' of species.— Upper canines 

 short, stout, distinctly recurved ; cingulum strong, forming a well- 

 detmed ledge on inner base of tooth, p^ larger than usual, not rarelv 

 equal in size to i^, as a rule with crown distinctly differentiated 

 from shaft ; present in all specimens examined, most of which are 

 fully adult, but none very aged. Posterior basal ledge of p^ lar-e 

 sharply marked off by a notch from main cusp of tooth postero- 

 exterually where it develops a small projecting tubercle. Posterior 

 Jedge ot p smaller and much less distinctly marked off from tooth 

 though generally a minute notch is detectable postero-externally 

 the ledge is m some individuals slightly more projecting backward 

 on postero-internal than on postero-external corner of tooth m' 

 almost twice as long as broad. m= subequal to p .— i twice or 

 three times the bulk of i,. Lower canines short, stout, recurved • 

 cingulum very strong, forming a broad ledge, p, once and a half 

 to twice the size of i.^. Posterior basal ledge of p and p very 

 strong, sharply marked off from teeth by a notch postero-externally 

 mm, and m^ the ledge, though easily observable, is indistinctly 

 difierentiated from the teeth. Cingulum of p, distinctly projecting 

 antero-mternally but without any trace of minute tubercle (cf. Pt. 

 anetiamts). m^ normal, somewhat smaller than p . 



Palatc-rid^es.— 5 + 5 + 3. Pirst ridge terminating laterally at 

 front of canines; second at back of canines ; third at front of p^ - 

 lourth at back of p' ; fifth at middle of p^ ; sixth at middle (or front) 

 of ra ; seventh at front of m= (or back of m') ; eighth to tenth 

 behind m ; eleventh to thirteenth situated at palation border
