Biagnosk. — Similar iu skull, teeth, and external dimensions to 

 Ft. h. iomesi, but mantle averaging considerably brighter, and back 

 and rump usually of a more Front's brown tinge. A dark-coloured 

 phase occurs. Forearm 135-141-5 mm. Hab. Cagayau Sulu ; 

 Philippines genei'ally. 



Colour. — (1) Brighter phase: breast and belly, or at least 

 centre of breast, golden ochraceous or ochraceous-butf, with or 

 without a tinge of orange-buff; mantle similar (three specimens ; 

 ad. skin, teeth much Avorn, June, Cagayan Sulu, 95.7.30.2, topo- 

 type ; cJ ad. al., teeth very sliglitly worn, Dinagat, 77. 10. G. 8 ; 

 5 yg. ad. skin, Jan., Panay, 105445). — Back and rump varying 

 from a dark shade 01 Prout's brown approaching seal-brown to 

 almost typical Prout'.s brown, sometimes with a rather slight wash 

 of dark russet; practically uniform, or more or less conspicuously 

 sprinkled with silvery greyish-white hairs. — Breast, or breast and 

 belly, varying from rich golden ochraceous to a tinge intermediate 

 between i3utf and ochraceous-buff, in any case generally washed 

 with orange-buft'; on sides of breast and belly passing into dark 

 chestnut, this again darkening into the seal-brown of the flanks. — 

 Mantle rich golden ochraceous-butF, generally tinged with orange- 

 bufF and more or less clouded with tawny or hazel, j)articularly in 

 front near occiput and posteriorly near back ; passing through a 

 darker shade on sides of neck into the dark cinnamon-rufous or 

 pale chestnut of foreneck. — Crown of head similar to mantle, or 

 more clouded with brownish and grizzled with silvery hairs ; 

 passing through a gradually darker tinge on sides of head, into 

 seal-brown or chestnut seal-brown on throat. 



(2) Intermediate stages.— One skin ( cJ ad., teeth very slightly 

 worn, Jan., Panay, 105441) has the whole of the back nearly 

 uniform Prout's brown, and the mantle nearly uniform chestnut, 

 lightening to rich golden oohraceous-bufF in a transverse band 

 between shoulders. — In two skins ( $ iram., Jan., Panay, 105446- 

 47) the bright colour of the underparts is restricted to a narrow 

 space on the centre of the breast; mantle approximately as in 105441. 



(3) Dark phase: underparts seal-brown; a narrow space in 

 centre of breast washed with tawny or ochraceous; mantle very
