PTEROPUS CANICEPS. 195 



Ears. — Longer than in Ft. lujpomelanus and dohsonl ; iipper third 

 distinctly attenuated, owiii^- to flatly concave emarginatiou of outer 

 margin ; tip narrowly rounded off. 



Interfemordl. — Scarcely developed in centre. 



Fur. — Short, silky ; closely adpressed on back. Approximate 

 length, back 10-12, mantle li-5-l-i-5, belly 11-5-13-0 mm. Width 

 of hairy space of back about 41-47 mm. 



Fur of back extending as a narrow line of short, and closely 

 adpressed hairs along upperside of humerus and proximal fourth 

 or third of forearm. Tibia naked above, except for a few scattered 

 hairs on proximal third. 



Colour. — Two colour phases occur; in both, the head, mantle, 

 sides of neck, and foreneck arc oehraceous or ochraceous-buff or 

 cream-buff, generally with extreme base of hair dark brown ; in 

 one phase the dark brown colour of back, rump, breast, and belly 

 is strongly mixed with, sometimes more or less completely con- 

 cealed or replaced by, glossy silvery huffy or buffy straw-yellow ; 

 in the other phase the back, rump, breast, and belly are uniform 

 dark mars-brown or russet mars-brown. 



(1) Grizzled phase: 5 yg. ad. skin, Batchian, type of species 

 (60.1.10.1). — Back and rump glossy silvery buffy heavily mixed 

 with seal-brown and blackish hairs. On front half of dorsum the 

 dark and pale hairs are nearly equal in number, on posterior 

 portion of dorsum and on rump the pale is largely in excess of the 

 dark clement. — Breast, belly, and flanks pale silvery greyish with 

 a faint tinge of cream-buff; base of fur slight!}' darker. — Mantle 

 and sides of neck buffy, shading to cream-buff on occiput and to 

 ochraceous-buif in shoulder region ; foreneck slightly darker than 

 sides of neck and suffused with pale wood-brown. Hairs of" mantle 

 and sides of neck seal-brown at base. — Crown and forehead similar 

 to mantle, all hairs dark brown at base. Sides of head and throat 

 mixed cream-bufly and dark brov/n. 



A second skin ( 2 ad. skin, teeth much worn, Batchian, 7.1.1.243) 

 is similar to the type in the general style of coloration, but differing 

 in many details : — While the dark-coloured hairs of back and rump 

 are seal-brown or dark vandyck-brown as in the type, the pale 

 hairs are different in tinge, huffy straw-yellow, and rather more 

 thinly spread, nowhere completely covering the dark fur. — Breast, 

 belly, and flanks dark vandyck-brown, approaching seal-brown, 

 thickly mixed with hairs similar in colour to pale hairs of back, 

 making general aspect of underside of body much darker than in 

 typo of species. — Mantle, occiput, and sides of neck darker than 

 in type, between ochraceous-buff and oehraceous, shading almost 

 to russet in shoulder region; extreme base of fur dark brown. 

 Foreneck similar to sides of neck, but thickly mixed with dark 

 brown hairs. — Crown somewhat darker than mantle, approaching 

 clay, with dark brown bases to the hairs. Sides of head and throat 

 similar to foreneck. 



The type of Ft. affinis Gray (jjuv. skin, Gilolo, 02.10.21.4) 

 is oil the wliole similar to the second example described above, but
