According to M. Levaillant, these two last described are male and 

 female ; and he adds, that the young birds of both sexes have the 

 throat, and fore part of the neck dirty white, the rest of the under 

 parts greyish ; ends of the tail feathers dirty rufous, and those parts 

 which in the adult are black, in young birds are brown ; but the spot 

 of the wing is seen at all ages. 



Mr. L. states, that although the general appearances are as above, 

 he once found the external plumage of a male ; but on dissection, was 

 surprised to find an egg ready to be excluded ; and hence seems to 

 think, that an old female, as in some other birds, may take on the 

 dress of a male. 



The eggs are pure white, six lines long, by four broad, and 

 narrow at one end; these have been found in various nests, and among 

 others those of our Rufous-crowned and Citrin Warblers. 



The bird is met with about Roude Bosch, Niuwe land, Constance, 

 and in the valley which separates False from Table Bay, as well as 

 in other parts; is migratory, coming in August, and departing in 

 February and March. M. Levaillant found an egg, supposed to 

 be of this bird, in several of the nests of the Great-tailed Warbler, 

 which are made of down, oval in shape, with an entrance two-thirds 

 from the bottom; and wonders how it could get there ; in respect to 

 those found in the nest of the Rufous-crowned Warbler, he observes, 

 that the egg is of twice the size of that of the bird in whose nest it is 

 deposited. — M. Temminck joins this to the last described, as one and 

 the same species. 



The late Mr. S. Daniells met with this species in Ceylon,
