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.— W. F.]

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. albicolUs paranensis.
