and sleuder, sagittal crest none. Dentition weak, but structure 

 of teeth unmodified ; posterior ledge of cheek-teeth distinct, but not 

 very strongly marked off from teetli. Ears small, broadly rounrJed 

 off at tip, halt expotcd. Tibia furred above. Fur unusually pale- 

 coloured (silvery bufty-white or silvery cream-buff) with concealed 

 bases of bail's contrasting seal-brown ; mantle rich ochraceous-buff : 

 head not striped. Size small : ibrearm U4'5-lUl mm. llah. Coram, 

 Amboina, Timor. 



Skull. — Deflection of brain-case slightly greater than usual, al- 

 veolar line if projected backward passing through middle of vertical 

 portion of su{)raoccipital. Ilostrura short, slender, somewhat com- 

 pressed laterally. Urbits unusually large, larger than or equal to 

 lachrjmal width of skull ; front of orbit above middle or posterior 

 half of p'. Sagittal crest undf\'eloped, the temporal crests remaining 

 separated (usually widely separated); postorbital therefore ahvays 

 considerably broader than interorbilal constriction. Coronoid 

 process weak, front margin considerably sloping backward ; coronoid 

 height of mandible much less than length of lower tooth-row (c-mgj, 

 generally even less than maxillary tooth-row. 



Teeth. — Weak. Upper canines very slender, .slightly recurved, 

 vertical groove on front face deep ; cingulum moderate, p' rvidi- 

 mentary, terete, deciduous. Posterior basal ledge of p' and p' well 

 developed, rather indistinctly marked off from teeth (postero-external 

 notch ill-detined or wanting), in p* more developed on postero- 

 internal than on postero-external corner of tooth, m^ slightly 

 larger than p^ and m.,. — i.^ twice to twice and a half the bulk of ij. 

 pj about twice the size of i.,. Posterior hdge of p.^, p^, and m^ 

 moderate ; a small notch between ledge and base of outer main 

 ousp generally present in p^ and p^, sometimes in m^. m^ snbequal 

 to p,. 



Ears (dried skins). — Small, half exposed. Scarcely any emar- 

 gination of outer margin below tip ; tip broadly rounded off. ]S'aked 

 posteriorly, except at base. 



Fur. — Moderately long, soft, silky ; directed posteriorly on back, 

 but not closely adpressed. Length at Jiiiddle of back about 12, 

 mantle V6, middle of belly 11 mm. Above, humerus and proximal 

 half of forearm furred, the hairs decreasing in length and becoming 

 more thinly spread distally ; tibia densely furred to ankle. 



Colour (cotypes, perhaps slightly faded). — Back and rump silvery 

 buffy-white or silveiy cream-buff, with a slight wash of palo 

 cinnamon laterally, along membranes. — Breast, belly, and fianis 

 silvery greyish-white faintly tinged with cream-buff. — Mantle, sides 

 of neck, and forencck rich ochraceous-buff (or with leanings to 

 ochraceous). — Occiput similar to mantle ; crown, sides of head, chin, 

 and throat similar to underparts, or with a slightly more pronounced 

 buffy wash. — Concealed bases of hairs everywhere dark brown 

 (approximately seal-brown) ; on back and rump the dark bases are 

 much longer than the pale-coloured tips, towards the manlic the 

 dark bases decrease, the light ti])s increase in length ; on mantle 

 and hcail th:> ])ale tips are equal in length to or longer than the
