I am unable to find any constant differences between specimens from Bahia 

 (including the type of -S'. s. pallid i cent ris Berljj.), and those from Goyaz (Baer, 

 Natterer, V. deu Steineu, Custelnau et Deville), (Juyaba (Behn), and Minas Geraes 

 (Campanha). Skins from Parand (Caritiba), Santa Cathariua, and Rio Grande do 

 Sul are much darker, deep fnlvous on the belly, as pointed out by Connt Berlepsch 

 {I.e.). The type of S. simil/'s from Corrieutes, however, proved to be indis- 

 tinguishable from Bahia and Goyaz examples — hence -S'. «. pallidiventris becomes 

 a synonym of similis, while the dark-bellied race from South-eastern Brazil would 

 require a new name. Specimens from Rio de Janeiro and S. Paulo are variously 

 intermediate between the two forms, some being nearer the northern race, others 

 being very nearly as dark as examples from Rio Grande do Sul. 



Although I have examined thirty-sis specimens, this material was not sufficient 

 to exactly define the range of the two or three geographic forms.

This series agrees exactly with several topotypical specimens from Paraguay 

 (Bernalcue, near Asuncion). Freshly moulted birds are warm chocolate-brown on 

 the back, and the lower parts show a strong ochraceous tinge. In worn plumage 

 the upper surface is dull greyish brown, especially rump and upper tail-coverts, 

 while the breast and the middle of the abdomen appear nearly white, the flanks and 

 under tail-covevts alone being pale ochraceous. 



In immature birds the throat is duller black and mixed with brownish, the bill 

 nearly uniform blackish.
