No. 2 is evidently a young bird. 



Measurements of male and female of the I, 'pliiUl^ancc from 



r^-i 



A\^e have young and adults of both these birds ; in the first lot 

 all were like Z^;/^ii7/^jjr/;«^, and were sexed by J. Stephens and 

 Morton and said to be males and females ; in the second lot all 

 are alike, and have only the throat and ear-coverts white, they 

 were sexed by J. Stephens, and said to be males and females ; 

 some are young birds with a dull cap, but the white throat and 

 ear-coverts distinct. If these birds then, have been correctly 

 sexed, and there is no reason to believe otherwise, then they must 

 be of two distinct species although found on the same Islands.

Stephen has sent a good series from which it appears that the 

 birds with the deep rufous undersurface and black cross bands 

 are younger than those with a paler or fawn coloured breast and 

 hastate black tips to the feathers ; there is one all slaty-black 

 bird marked as a female, and two A. aJhif/idaris, with white under- 

 surface also marked as females. I am afraid they must all belong 

 to the one species and go under Grray's name of A. aJhirfularis.
