Sect. A. Species pileo cinereo. 



This section contains four species known to me, which 

 may be recognized by the following diagnoses : —

Natterer obtained during his travels in Brazil examples of 

 both this and the next following closely allied species. Un- 

 fortunately Temminck appears to have described and figured 

 the northern form, Avhile Prince Maximilian described the 

 southern form under the same name. So far as I can make 

 out, Herr von Pelzeln, in his ' Ornithologie Brasiliens/ has 

 reversed the localities of the two species.
