9:* 



figured and described as the adult female, while the latter is the specimen from which I have 

 taken my description of the immature male. 



With this series of specimens before me, I think I may safely refer the plumage described 

 by Dr. Briiggemann as that of the " female as well as of the young," to young birds only. As 

 his specimens were no doubt carefully sexed at the time, it would appear that the young female, 

 as well as the young male, possesses a yellow throat. Since writing the above, Dr. Meyer has 

 kindly forwarded to me, for examination, two yellow-throated specimens collected by him at 

 Menado, and labelled " female :" these, from the texture of the feathers, are undoubtedly young 

 birds. 



The only species of this group which has the entire underparts yellow in the adult female 

 is C. sangirensis ; but here we find the throat also yellow in the males during their moult. In 

 C. auricejjs the adult female has the throat white ; but in very young specimens, whose feathers 

 have not yet quite passed out of the down, the throat is yellow ; and this appears to be generally 

 the case in young birds of this group. 



The adult male I have figured and described is from one of Mr. Wallace's specimens in the 

 Marquis of Tweeddale's collection.
