109. Crithagra ruficauda 



Head grey, with two white lines beneath the eye, and 

 a larger one above : upper plumage isabella, striped with 

 brown : beneath, whitish : quills black : tail bright rufous. 



Inhabits South Africa. Mus. Nost. 



Total length 4i inches ; bill, gapef^; wings 2-f^Q ; tail, be- 

 yond, Ij'g; ditto, base l-f| ; tarsus i. This is a most extraor- 

 dinary bird, having all the outward aspect of a Pyrrhulauda, in 

 regard to colour, but with the real structure of Crithagra ; this 

 affinity being manifested by the bill and feet. The tertials 

 are not lengthened ; and the hind toe and claw is scarcely 

 shorter than the tarsus. In its grey head, and rufous tail, it 

 shows its analogy to Dasycephala, and all those groups simi- 

 larly coloured : the wing covers are rufous, but not so bright 

 as the tail ; and the base of the lesser covers are black : the 

 rump and upper covers are like the tail, the feathers of which 

 are more or less marked with a longitudinal black stripe at the 

 end of the shaft : the bill and feet are pale.

Back of the head, neck, sides of the throat, and

 under plumage, yellow : belly and vent white.

 yond, ^ ; ditto, base 2\ ; depth of the fork fg ; tarsus ^ ; hind 

 toe and claw 11. Fore part of the entire head, as far as the 

 'ears, dingy but glossy yellow, graduating into the clear cine- 

 reous, which extends from the nape to the interscapulars, and 

 round to the sides of the throat and breast : lores dusky : the 

 yellow of the breast becomes brighter as it descends, and leaves 

 the belly and thighs white : edges of the quill and tail feathers 

 bright yellow. Claws long, and very slender.

Above, greyish olive, striped with dusty : rump and
