AGYRTUIXA.

Genus AGYRTRINA, n. gen. 



We propose this name for A. icliitehji (Boucard), and it will be 

 aA'ailable for the species classed under Agyrtria Reichenbach by 

 Brabourne & Chubb, ' Birds of South America/ i. pp. 112, 113 — as 

 we find, upon further research, that Reichenbach proposed Agyrtria 

 as a substitute name for Thaiimantias Bonaparte, which equals 

 Polytmus Brisson. 



In this genus the culm en is feathered at the base, the anterior 

 portion of the nasal covers is exposed, the bill is straight, and the 

 tail emarginate.
