in color with coelicolor than with paradisea. Their dimensions are: 
Male—wing 72, tail 52.5; female—wing 72, tail 50 mm., while Hell- 
mayr gives wing 76-81 (male), 74—72 (female); tail 52-60 mm. 
CALOSPIZA XANTHOGASTRA (Sclater): Yellow-bellied Spotied Tanager 
Calliste xanthogastra ScuaTerR, Contr. Orn., 1851, pt. 1, p. 23 (“Rio Negro’”’). 
SPECIMENS COLLECTED 
lad. o, 3 ad. 2, Sao Gabriel, Rio Negro, Amazonas, Brazil, January 6-17, 
1931. 
The adult male has the edges of the feathers of the back bluer than 
do the females. Two of the four birds collected had “active gonads” 
indicating that the breeding season (if definite) must be sometime 
around January. 
Comparison with specimens from ‘‘Bogota’’ and especially from 
eastern Ecuador (near Macas, Oriente), and eastern Peru (Napo) 
upheld Hellmayr (Catalogue of the birds of the Americas, pt. 9, 1936, 
pp. 104-105) in synonymizing rosirata Berlepsch and Stolzmann with 
zanthogastra. 
CALOSPIZA NIGRO-CINCTA NIGRO-CINCTA (Bonaparte): Black-banded Tanager 
Aglaia nigro-cincta Bonaparte, Proc. Zool. Soc. London, vol. 5, ‘‘1837’=June 
1838, p. 121 (‘‘that portion of Brazil bordering on Perw’’). 
SPECIMENS COLLECTED 
lad. @, 1 ad. 2, Sao Gabriel, Rio Negro, Amazonas, Brazil, January 19, 1931. 
Both specimens had the gonads in active condition. 
The male has the sides and flanks darker blue than in two males 
and two unsexed birds from ‘‘Bogota,’’ Colombia, four from eastern 
Ecuador, and three from Rio Surutu, Bolivia. The Sao Gabriel male 
is also smaller than the other three, having a wing length of 63 mm. 
as opposed to 67 and 72 mm. in the Bogota birds, 65.5-70.5 mm. in 
the Ecuadorian examples, and 71, 71.6, and 74 mm. in the Bolivian 
birds. 
The female collected is probably not fully adult, as it is not so 
highly colored as the male, the breast being largely grayish instead 
of black and the sides and flanks more grayish also. It has a wing 
length of 60 mm. as against 64 mm. in a female from “Bogota,” and 
63.5 and 66 mm. in two from eastern Ecuador. 
On the other hand, Hellmayr (Catalogue of the birds of the Ameri- 
cas, pt. 9, 1936, p. 127, footnote) finds “apparently no local variation 
in this species, birds from such widely separated localities as Roraima, 
the Caura Valley, and ‘Bogota’ agreeing with others from northern 
Peru.”
