Amazons, Etc. 125 



Yellow-thighed Caique (Galea xanthomera). 



Only a female is sexed. It probably differs from the male as in 

 the allied species. 



We now come to some African Parrots, which (although referred 

 to the Pionince) would, I think, be more conveniently placed with 

 the few other African forms of the subfamily Psittacince. I shall 

 therefore commence Chapter XXIV. with these ; not, of course, 

 transferring them to the next subfamily, but merely placing them 

 in the same chapter with them. 



Chapter XXIV. 

 AFRICAN HONING. 



Levaillant's Parrot (Pyocephalus robustus). 



The beak of the male is slightly narrower and considerably longer 

 than that of the female, and in the Museum examples the terminal 

 hook is far more acute. 



Brown-necked Parrot (Pceocephalus fuscicollis). 



Only a male is sexed in the Museum series, but it probably has 

 a longer beak, with longer terminal 

 hook, than the female. 



Jardine's Parrot 

 (Pceocephalus gulielmi). 



The male is larger than the female, 

 and has a considerably heavier and 

 more powerful beak. 



Brown-headed Parrot 



(Paiocephalus fuscicapillus). 



The male is larger than the female, 

 but the beak exhibits little, if any, Senegal parrot. 



Structural difference. {From a Photograph by Miss Alderson.) 



Senegal Parrot (Paiocephalus senegalus). 



No specimens are sexed in the Museum, but the male is probably 

 larger than the female, with a rather heavier beak. 



Meyer's Parrot (Paiocephalus meyeri). 



The male is larger than the female, and his beak is much more 

 powerful, with a longer terminal hook.
