I have hitherto confounded this species with the G. tombacea, but 
the examination of several examples of the latter bird in the conti- 
nental museums has convinced me that they are quite distinct, the 
tombacea presenting no appearance of the fuscous crown which di- 
stinguishes this species. In one of my specimens, apparently the most 
adult, the green descends much lower down than in others I have 
seen. ‘The two outer rectrices of this bird are, as is usual in this 
genus, abnormally small. The first outer normal pair are rufous, 
tipped and externally edged with green. This green is blackish 
below, but above vivid as the back. The next two pair are wholly 
rufous. The middle four are vivid green above, and blackish-green 
below; the submedial pair having some rufous colouring inwardly 
towards the base.

Thave lately seen many specimens ¢ and ¢? of this species. The 
male has a white bar on the throat, as in G. albirostris, with which 
it is certainly very closely allied. In his ‘Conspectus Zygodacty- 
lorum,’ Prince C. L. Bonaparte unites this species with G. leuco- 
gastra, with which it has nothing to do. In the ‘Conspectus 
Anisodactylorum,’ the origin of this error is attributed to an opinion 
of mine that they were identical (!), which however I never either 
expressed or entertained. 
9. cyanicollis, Cassin. Synopsis, p. 6. sp. 8. 
Specimens of this bird in the Berlin Museum,—the types of G. 
cyanopogon, Cab.,—are from Cameta, which is on the south of the 
Amazon, in the province of Para. The female is pale rufous below, 
instead of chestnut-red.
