Birds of Paraguay. 
with specimens in the National Collection, however, 
I find that they are identical with Pogonotriccus eximius of 
Temminck, as Dr. Ihering has already suggested. 
[This species is resident and not uncommon in the forests 
of this district.— -fV. F.]

[This tiny Tyrant-bird is by no means common in our 
woods, although widely distributed through the country. 
In the dim lights of the large forests it is very hard to 
distinguish it from Ornithion obsoletum , which occurs much 
more frequently with us.— W. F .]

Hemitriccus barber enae Bertoni, Aves Nuev. Paraguay, 
n. 124.

a. ? ad. Sapucay, April 11, 1903. 
Bill horn-coloured, above, pale buff at base of lower 
mandible; tarsi and feet bluish slate-coloured ; iris brown. 
b. $ ad. Sapucay, June 17, 1904. 
These two individuals are identical with others from 
Brazil, in the British Museum series. I agree, therefore, 
with Dr. Ihering that Hemitriccus barberence of Bertoni 
should be placed as a synonym under the present species.
