SPECIMEN COLLECTED 
lim. 9, Brazil, Cucuhy, Rio Negro, February 7, 1930. 
Although this little rail has been recorded from many places from 
the Guianas and Venezuela south to northern Argentina, it is very 
local in its distribution. It does not seem to have been recorded in 
print from the Rio Negro area before. 
The specimen is in fresh plumage. 
Family HELIORNITHIDAE: Sun-grebes 
HELIORNIS FULICA (Boddaert): Little Sun-grebe 
Colymbus fulica BoppAERT, Table des planches enluminéez ... , 1783, p. 54

lad. 9, lim. 2, Brazil, Salto do Hud, Rio Maturac4, November 20-21, 1930.

just beginning to grow new rectrices; the other is in an earlier stage

SPECIMENS COLLECTED 
lim. 6, Brazil, Rio Cauabury, below mouth of Rio Maturacdé, November 6, 
1930. 
The only sun-bittern collected is a bird in its postjuvenal molt. 
Holt records that a pair was seen on the Cauabury, probably on the 
day the above specimen was collected. At San Antonio, on the Upper 
Orinoco, he noted a free, but apparently man-raised, sun-bittern 
walking about in the vicinity of the village.
