(1 Oct. 1908: Telew Is.\ 



Diagnosis. — Allied to Pt. 2^sehiphon, but with rather larger orbits, 

 luuch longer canines, larger i., and p,, miicli shorter fur, less thicljly 

 clothed forearm and tibia, naked feet, much paler colour, and larger 

 external dimensions. Chocolate above, psiler brown beneath, con- 

 spicuously sprinkled with long, coarse, huffy or whitish hairs ; 

 mantle deep tawny. Forearm 1.31'5 mm. HaO. Pelew Is. 



SJcuU. — Characters and general size as in Pt. 2^-^&^(tp^^on, but 

 orbits slightly larger (13'2 mm., as against 12-2-V2-S in psela^^hon). 



Teeth. — Essential characters as in Pt. pselaplion. Posterior 

 cinguUim of upp3r incisors less expanded than in pselaplion. Upper 

 and lower canines considerably longer ; upper canines from alveolar 

 border to tip 9'2 mm., m pselaplion 7'7 mm. ; shape of crown, and 

 excessive development of cingulum as in pselaplion. p' slightly 

 larger, crown a little more differentiated from shaft, i, markedly 

 larger, more than thi'oe times the bulk of i^. Pj much larger, 

 about twice the size of m,. Posterior basal ledge of p^, p^. and m^ 

 extending inward distinctly beyond the line of the inner longi- 

 tudinal ridge of the tooth, thus exhibiting a slight tendency to 

 form a lingual ledge (compare Pt. samoi'nsis and a)ieliani(s). No 

 transverse depression in inner ridge of nij. 



Palate-ridges.— + 5 -^'A:, arrangement as in Pt. pyselaplton An(i 

 nawaiensis (p. 281). 



Ears. — Small, half exposed ; falling short of hinder corner of aya 

 by about K3 mm. Subtriangular in shape ; inner margin evenly 

 convex ; outer margin very Hatly convex (nearly straight) from base 

 to tip ; tip rounded off. Naked posteriorly, except at base. 



lym^/s.— About 30 ram. apart at origin from sides of back. 



Inter femoral. — Undeveloped in centre. 



Fur. — Much shorter than in 7^^ pselaplion ; as in that species, 

 everywhere mixed with longer, coarser (buffy or whitish) hairs. 

 Approximate length of longest hairs, back 20, mantle 21, middle of 

 belly 19 mm. 



Above, humerus covered with rnther long, thinly spread, adpressed 

 hairs almost to elbow. Elbow naked ; proximal third of forearm 

 clothed with very thinly spread, adpressed hairs, the skin everywhere 

 showing through. Proximal two-lhii-ds of til)ia I'urred, but hairs 

 more thinly spread than in psthiphon-., distal extremity and foot 

 practically naked.- — Eeneath, hairing on membranes as in pselaplion. 

 Proximal fourth of forearm and tibia very thinly haired. 



Colour. — Type of species ( (5" ad. al., teeth almost unworn): 

 Back and rump cliocolato, rather conspicuously sprinkled with long 

 p-hinv whitish-grey or bufi'y-grey hairs. — Breast, belly, and flanks 

 jialcr than ii]i])ersidp. lietween vandyf];-brown and mars-brown,
