Bill black above, dark slate-coloured below; tarsi and feet 
dark slate-coloured ; iris brown. 
d, e. $ $ ad. Sapucay, April 4, 19, 1904. 
These five examples agree perfectly well with S. erithacus 
of Lichtenstein, and I see no reason for upholding Acanthurus 
microrhynchus of Bertoni as a separate species. 
[A rather common bird with us; it can be met with in 
all the large forests, although not common in the smaller 
woods.— IF. F.]

Xiphocolaptes paranensis Bertoni, Aves Nuev. Paraguay, 
p. 68. 
a . $ ad. Sapucay, August 31, 1904. 
Bill black ; tarsi and feet olive-green; iris reddish brown. 
This individual specimen is somewhat darker in colour 
above and below than those in the National Collection, and 
the rufous of the wings and tail is also deeper in colour. It 
may, therefore, be regarded as a subspecies under the name 
of X. albicollis paranensis.
