Diar/nosis. — Similar to Pt. a7'uensis, but colour of fur nearly 

 uniform light yellowish above and beneath. Forearm 179-187'5 mm. 

 Ilab. Key Is. 



SkuU and teeth. — Rostrum markedly shorter than in Pt. melano- 

 pogon: from front of orbit to tip of nasals 25-27-7 mm., against 

 28"2-31'2 in Pt. melanopogon; front of orbit vertically above back 

 of p\ in Pt. melanopogon above front of m'. Teeth not differing 

 appreciably from those of Pi*, melanopogon and aruensis. 



Palate-ridges. — As in Pt. melanopogon. 



Wings. — Membranes less closely approximated than in Pt. melano- 

 pogon, about 21 mm. apart at origin from sides of back. 



Fur. — Length and distribution of fur as in Pt. ainunsis. Approxi- 

 mate length, back 11-13, mantle and belly 14-15 mm. Least 

 ■width of furred space of back about 45-47 mm. 



Colour. — c5' ad. al., teeth worn, 82.7.27.3: Back and rump yel- 

 lowish cream, tinged with pale maize-yellow on back and with buff- 

 yellow on rump. — Fur of breast, belly, flanks, and crissum cream- 

 coloured at base, tipped with buif-yellow on breast, belly, and flanks, 

 and with light straw-yellow on crissum. Underside of humerus and 

 woolly hairs on underside of membranes pale buify. — Mantle, sides 

 of neck, and Ibreneck deep chrome, palest on foreneek, shading into 

 light buft'-ycllow on crown and sides of head, and into cream on 

 muzzle and throat. 



Individual variation in colour apparently small. All the indi- 

 viduals examined differ only in the deeper or paler tinge of the 

 colours.
