Amazons, Etc. 121 



Salvin's Amazon (Chrysotis salvini). 



The male is larger and more brightly coloured than the female, 

 and his beak is considerably longer, slightly broader, and less 

 arched. 



Yellow-cheeked Amazon {Chrysotis autumnalis). 



The male is larger than the female, and the scarlet on his fore- 

 head broader ; the female also shows less scarlet but more yellow on 

 the cheeks. The beak of the male is much longer and heavier, with 

 longer terminal hook. 



Red-tailed Amazon (Chrysotis braziliensis). . 



Judging by the sexed specimens in the Museum, the male is 

 larger than the female, much redder on the head, the cheeks much 

 more purplish-blue ; but, of course, the single female may be a 

 variety. The beak of the male is narrower at the base, but fuller 

 towards the tip, with a heavier terminal hook. 



Bodinus' Amazon (Chrysotis bodini). 



Only the female is sexed, but what I take for the male is larger, 

 shows more red on the front of the crown, more lilac on the nape, 

 also a slightly longer and broader beak. 



Festive Amazon (Chrysotis /estiva). 



The male is larger than the female, with a longer and more 

 regularly tapering beak ; the terminal hook is variable (probably 

 owing to the different ages of the specimens), but is frequently 

 broader. 



Bed-fronted Amazon (Chrysotis vittata). 



In the Museum only a male is sexed; but, after comparing the 

 six specimens, I conclude that its beak is probably longer and 

 more slender than that of the female. 



Pretre's Amazon (Chrysotis prcetrii). 



Only a male is sexed (not female, as noted in Catalogue) ; the 

 beak is probably broader than in the female. 



White-browed Amazon (Chrysotis albifrons).* 



The male has a longer beak, with a longer and more slender 

 terminal hook. 



Yellow-lored Amazon (Chrysotis xantholora). 



The beak of the male is more pointed towards the tip, the 

 terminal hook being longer. In the only sexed female in the Museum 

 series the crown is mostly blue, the forehead only being white; it 



* In the Museum Catalogue, Count Sa'vadori says of this species (vol. xx. 

 p. 312) : " Young or Female. — Differs from the adult male in having the bastard- 

 wing and primary coverts green, with no red."
