Colour. — Very similar to Ihiit of bright- coloured individuals of 

 C. s. spldnx (p.'euO). 



Adult males (nine skins : Penang ; Johoro ; Singapore ; Batam ; 

 Karimau ; Sarawak) : — Back in brightest-coloured specimens a 

 tinge of brown somewhat approaching dark raw-umber and very 

 conspicuously suffused with warm russet or a tinge between russet 

 and tawny-olive; in duller-coloured specimens brownish olive or 

 brownish bistre suffused with raw-umber. Crown similar to back 

 or slightly darker. Centre of breast and belly lighter or darker 

 olive-drab. Sides of neck, sides of breast, and flanks varying from 

 nearly tawn}' (palest extreme\ through lighter or darker cinnamon- 

 rufous, to light warm chestnut, in any case contrasting with colour 

 of centre of breast and belly. Ears conspicuously edged with white ; 

 metacarpals and phalanges usually whitish or brownish white, 

 contrasting with dark membranes. 



Adult females (twenty-four skins : Penang; Johore ; Singapore; 

 Batam; Kariman ; Buutok): — Differing from males chiefly by the 

 paler (less saturated) colour of the neck and flanks ; back averaging 

 darker. Back brownish olive or brownish bistre, sometimes uni- 

 form, rather more often washed with a pale tinge of biown, not 

 infrequently with russet, but never as bright as in the brightest- 

 coloured males. Head similar to back or somewhat darker. Breast 

 and belly some tinge of drab, nearly always more or less suffused 

 with raw-umber or tawny olive, sometimes uniform drab or even 

 greyish drab. Sides of neck and sides of breast some tinge of 

 tawny, or tawny olive, or tawny russet, this colour not extending 

 quite as far back along the flanks as in adult males, and not as 

 strongly contrasting with the colour of the breast and bellj'. Ears, 

 metacarpals, phalanges, and membranes as in males. 



The above-described adult males date from February, April, July, 

 and August; the females from July, August, and October. So far 

 as this series goes the seasonal changes in colour are hardly 

 appreciable.

 (nearly slate-brown), in individuals approaching maturity often 

 brownish bistre or this colour slightly washed with raw-umber.

 light tawny-olive.
