from the Caura, Venezuela, do not appreciably differ from others 
from upper Amazonia. He had three specimens from the Rio Negro 
(Marabitanas, Séo Joaquim, and from below Lamalonga and Santa 
Isabel). He concludes that hyacinthinus could not be maintained 
as a race, to say nothing of its use as a species as in Chubb’s book. 
The status of hyacinthinus as a possible northeastern subspecies of 
C. violaceus must remain unsettled until some one with ampler mate- 
rial looks into it. The type locality of hyacinthinus is Canuku 
Mountains, British Guiana, the opposite end of the range of the 
species from Peru, the locus of typical violaceus. 
Two of the Venezuelan birds show signs of molt in the primaries.

SPECIMEN COLLECTED 
1 ad. 9, Venezuela, Puerto Ayacucho, Rfo Orinoco, May 21, 1931. 
The present specimen is slightly paler above than another female 
from the Rio Parime, northern Brazil, and also differs from it in having 
a shorter bill (26.8 mm. in the Venezuelan bird as against 30 mm. in 
the Brazilian, the culmen being measured from the base). More 
material is needed to determine the limits of individual variation in 
this wren. 
This is a bird of the savannas from northern Brazil north to Vene- 
zuela and British Guiana.
