Bill rosy pink at base, black at tip; feet black; iris

[This species is fairly common throughout the district, 
its small nest being usually suspended from a blade of 
thatching-grass or a piece of string hanging from the roof 
of a house; in fact, any place seems suitable for it. 
Two eggs only are laid. This species is one of the early 
breeders, incubation having been well advanced in one clutch 
at the end of September.— W. F.]

Thalurania eriphile eriphile Hellmayr, Nov. Zool. xv. 
p. 76 (1908). 
a. ad. Sapucay, March 31, 1904. Wing 2’4 inch, 
tail 1*6 inch. 
Bill and feet black. Obtained in the neighbourhood of a 
dwelling-house. This specimen is fully adult and in newly 
moulted plumage. It agrees with the diagnosis of the 
species given by Mr. Hellmayr (/. c.). 
Mr. Bertoni was the first to record this bird in Para¬ 
guay, when he described it as a new species under the 
title of Chlorostilbon cyanothomx (Aves Nuev. Parag. p. 59). 
Dr. Ihering, however, is of opinion (/. c.) that it is identical 
with Thalurania eriphile .
