These specimens agree very well with Temminck’s descrip¬ 
tion and figure of H. 7'ufomarginatus, and also with the 
examples of the species in the collection of the British 
Museum. I agree, therefore, with Dr. Ihering and Mr. 
C. W. Richmond that Dendrooecia erythroptera of Bertoni 
must be placed as a synonym of the present species. 
[Like the preceding and about as abundant.— TV. if.] 
84. Formicivora malura. 
My other a malura Temm. PI. Col. ii. pi. 353. figs. 1 & 2 
(1825 : Ypanema). 
Formicivora malura Sclater, Cat. B. Brit. Mus. xv. p. 254; 
Sharpe, Hand-list B. iii. p. 26 (1901). 
This specimen agrees very well with TemminclPs figure, 
and also with another example in the National Collection 
from Ypanema, collected by Natterer. The species is new 
to the avifauna of Paraguay. 
85. Cham^sa brevicauda. 
Turdus brevicaudus Vieill. N. Diet. d'Hist. xx. p. 239

a. $ ad. Sapucay, June 10, 1904. 
Bill, tarsi, and feet pale pink ; iris brown. 
This example is identical with others in the National 
Collection from Eastern Brazil, and the species is recorded 
here for the first time from Paraguay. 
[A rare bird with us, living solitary in the large forests. 
In habits this species is identical with the Thrushes, 
and in the dim light and thick undergrowth of the w r oods it 
is not easily to be distinguished from them.— TV. F]
