SPOROPHILA MINUTA MINUTA (Linnaeus): Minute Seed-eater 
Lozia minuta LINNAEUS, Systema naturae, ed. 10, vol. 1, 1758, p. 176 (Surinam). 
SPECIMENS COLLECTED 
1 ad. 9, Brazil, Cucuhy, Rio Negro, February 1, 1930. 
1 ad. o, Venezuela, Puerto Ayacucho, January 6, 1930. 
The male has the top of the head and the upper back dusky brownish 
olive. A series of a dozen males reveals about half are in this plumage 
while the other half have these parts cinereous; whether the latter are 
the truly adult birds I cannot say with certainty, but it seems that 
they are. The underparts in the males also vary in darkness. The 
present specimen is very pale, agreeing in this respect with a bird from 
Bogota, Colombia, and differing from others from British Guiana, 
Venezuela, Brazil, Colombia, Trinidad, and Tobago. The female 
collected, is whiter on the abdomen and less tawny, more olivaceous, 
above than others from Colombia, Venezuela, and British Guiana. 
SPOROPHILA CASTANEIVENTRIS Cabanis: Chestnut-bellied Seed-eater 
Sporophila castaneiventris CABANIS, in Schomburgk, Reisen in Britisch Guiana, 
pt. 3, 1848 (=1849), p. 679 (Cumaka, coast of British Guiana). 
SPECIMENS COLLECTED 
1 ad. o, Brazil, Rio Amazonas, Amazonas, September 20, 1930. 
1 ad. @, 1 ad. 2, Brazil, Sao Gabriel, Rio Negro, Amazonas, January 6-13, 
1931. Siar ths 
These specimens have been compared with others from British 
Guiana, Brazil, and Peru, all of which together bear out Hellmayr’s 
action (Catalogue of the birds of the Americas, pt. 11, 1938, p. 226, 
footnote) in synonymizing S. ¢. rostrata Todd with typical castanei- 
ventris. 
ORYZOBORUS ANGOLENSIS TORRIDUS (Scopoli): Lesser Chestnut-bellied Rice Grosbeak 
Lozia torrida Scopour, Annus I Historico-Naturalis, 1769, p. 140. (based on a 
bird brought alive by Jacquin to the Vienna Zoological Garden= north 
coast of Venezuela (Hellmayr)). 
SPECIMENS COLLECTED ¢ 
lim. #, Providencia, Rio Negro, Amazonas, Brazil, October 7, 1930. 
1 ad. o&, San Antonio, Upper Orinoco, Venezuela, March 9, 1931. 
1 ad. o', Puerto Ayacucho, Orinoco, Venezuela, May 12, 1931. 
The two adults have wing lengths of 56 and 58.5 mm.; tail 51 and 
51.5 mm., respectively, agreeing with the dimensions recorded by 
Hellmayr (Catalogue of the birds of the Americas, pt. 11, 1938, p. 
246). The gonads were enlarged, suggesting that the birds were 
taken in or near their breeding season. 
VOLATINIA JACARINA JACARINA (Linnaeus): Southern Blue-black Grassquit 
Tanagra jacarina LinnarEvs, Systema naturae, ed. 12, vol. 1, 1766, p. 314 (based 
on “Jacarini’” Marcgrave, Historiae rerum naturalium Brasiliae, p. 210: 
northeastern Brazil).
