 4724 (1869). 



Adult male (Type of species). General colour above light 

 rufous , more ferruginous on the crown of the head ; wing- 

 coverts bright ferruginous, forming a conspicuous shoulder- 

 patch; quills dusky brown, externally like the back; up- 

 per tail-coverts like the back ; tail-feathers dingy reddish- 

 brown with obsolete dusky bars under certain lights, and 

 with a slightly more reddish shade on the margins; fore- 

 head dusky blackish ; lores whitish , extending over the 

 eye and forming an eyebrow , the hinder portion of the 

 latter being pale ashy grey , like the ear-coverts , sides of 

 the face and sides of neck ; cheeks rather whiter ; throat 

 white, separated from the breast by a praepectoral collar 

 of black ; sides of upper breast ashy grey ; centre of breast 

 creamy white ; the abdomen , flanks , thighs , and under 

 tail coverts pale fulvous brown; under wing-coverts and 

 axillaries pale rufous buff; quills dusky below, pale rufes- 

 cent along the edge of the inner web. Total length 5.2 

 inches, culmen 0.65, wing 2.4, tail 2.15, tarsus 0.9. 



Adult female. Similar in colour to the male. Total length 

 5.2 inches, wing 2.25, tail 2.2, tarsus 0.85. 



In the type-specimens the edges to the quills and tail- 

 feathers are of about the same colour as the back ; but in 

 some others more recently added to the collection they 

 are rather more ferruginous, I am of opinion that in the 

 living bird the pectoral collar is not continuous, but that 

 there is a ring of black separating the throat from the 

 breast, while a broad black streak occurs on either side 

 below the hinder cheeks. The praepectoral ring is formed 

 by black tips to the feathers , whereas the black lateral 

 streaks are caused by the half of the feather being entirely 

 black longitudinally. 



It follows, therefore, that an entire revision of the
