Diagnosis. — Small; gonerall}' melanistic. Skull, total length 

 about 73-5-78-5 mm. ; forearm 185-201. Ilah. Philippines. 



Differential characters. — Most closely allied, and similar in size, 

 to Pt. V. natunce, from which it differs in the generally much 

 darker colour of the mantle ; but specimens occur (one, in a series 

 of six examined) which are indistinguishable in colour from 

 Ft. V. natunce. 



Colour. — (1) Melanistic specimens: S ad. skin, Catanduanes, 

 Sept. (Whitehead coll.) ; 95.1.3.2 : — Back and rump blackish, rather 

 heavily sprinkled with light greyish or buffy-gieyish. The whole 

 of the underparts blackish, washed with seal-brown on flanks and 

 anal region, and thinly sprinkled with light greyish. Mantle pale 

 vandyck-brown (approaching russet) rather heavily mixed with 

 blackish ; sides of neck blackish like foreneck. Crown and sides 

 of head similar to back ; temporal region slightly washed with 

 vandyck-brown. 



A specimen from Cebu ( cJ ;ul. al. ; ' Challenger' Exp. ; 82.7.27.2) 

 is very similar to the foregoing. 



In another specimen from Cebu ( S ad. skin ; ' Challenger ' Exp. ; 

 80.11.24.2) the back is suffused with pale vandyck-brown 

 (approaching russet), breast and belly slightly tinged with dark 

 vandyck-brown. Mantle blackish (thus much darker than back), 

 yides of neck and foreneck similar. Head blackish, somewhat 

 tinged with vandyck-brown on sides. 



A skin from Panay ( 5 ad., Steere Exp. ; 105439) is very 

 similar to the foregoing. 



A skin from Leyte ( $ ad., Steere Exp. ; 1054G1) has the back 

 and rump almost uniform mars-brown ; centre of breast blackish, 

 shading to dark chocolate on sides of breast, this again to vandyck- 

 brown on belly. Mantle walnut-brown, shading to dark vandyck- 

 brown on sides of neck, this again to dark chocolate on foreneck and 

 throat. Crown similar to mantle, though of a rather darker tinge. 



(2) Mantle much brighter than back: S ad. skin, Catanduanes, 

 Sept. (Whitehead coll.); 97.5.2.3 : — Indistinguishable in colour from 

 an average specimen of Pt. v. natunce (or malaccensis, or vampyrus). 

 Back seal-brown, thinly sprinkled with light greyish. Underparts 

 almost uniform blackish seal-brown from chin to interfemoral, 

 though with a rather faint tinge of dark chocolate on foreneck. 

 Mantle rich orange ochraceous-bulF, shading to ochraceous-rufous 

 on sides of neck. Crown vandyck-brown. — In the series examined 

 this is the only specimen from the Philippines with the mantle 

 bright-coloured, strongly contrasting with back.
