Four of these examples are quite identical with others in 
the National Collection from Brazil, while the fifth is 
inclining to “ Canary ” yellow above and below. However, 
this can only be regarded as a very pale variety. 
[This peculiar little bird is resident and is only met 
with where the woods are densest and darkest. It is very hard 
to detect, owing to its small size and the length of time it will 
remain motionless in one position. The sex can only be 
distinguished by dissection.— W. F.~\ 
125. PHYLLOSCARTES VENTRALIS. 
Muscicapa ventralis Temm. PI. Col. iii. pi. 275. fig. 2 
(1824 : Brazil). 
Phylloscartes ventralis Berlepsch, J. f. O. 1887, p. 131 
(S. Brazil) ; Sclater, Cat. B. Brit. Mus. xiv. p. 92. 
a, b. $ ad. Sapucay, March 19, 31, 1904. 
Bill black above, flesh-coloured below; tarsi and feet 
purple slate-coloured. 
c. $ ad. Sapucay, April 18, 1904. 
Bill dark horn-coloured, paler below at base; tarsi and 
feet purple slate-coloured; iris brown. 
These examples are identical with the single specimen in 
the National Collection. The species is new to the avifauna 
of Paraguay. 
[There are quite a dozen species of these birds somewhat 
like one another and hard to separate in the dim lights and 
shades of the forest. Their habits differ but slightly, so there 
is very little to say about them unless the nest can be 
discovered.— W. F.~\
