Colour. — Two " phases " are represented in the small series 

 examined : in most specimens the underparts are almost uniform 

 Wackish, in one hair-brown like back and crown. Corresponding 

 phases occur iu the allied races of the species. 



{a) Black-bellied phase ( c? ad., rf yg. ad., two $ ad. skins ; 

 U.S. N. M. nos. 104461, 62, 63, 65).— Back and rump blackish 

 or blackish seal-brown more or less heavily mixed with silvery 

 greyish-white or buffy-white hairs, producing the general effect of 

 a very dark shade of hair-brown. Individual variation not very 

 great, chiefly dependent on the greater or less preponderance of the 

 ])ale greyish element of the colour ; but even in the darkest 

 (blackish hair-brown) individuals the pale sprinkling is quite 

 conspicuous. — Breast, belly, and Hanks generally nearly uniform 

 blackish or blackish seal-brown inconspicuously sprinkled with 

 huffy or whitish-grey hairs ; in one specimen ( 5 ad., 104465, 

 with mantle rather paler than usual) the centre of the breast is 

 slightly washed with dull russet. — Mantle chestnut more or less 

 clouded with (sometimes nearly darkened into) seal-brown ; in one 

 specimen (104405) rather brighter, nearly cinnamon-rufous ; colour 

 gradually darkening on sides of neck, and passing on foreneck into 

 the general blackish seal-brown of the underside. The seal-brown 

 clouding of the colour of the mantle is (if present) generally con- 

 fined to the tips of the hairs; subapical portion same shade of
