Genus TROGON Brisson. 



Trogon Brisson, Om., i, 1760, 42; iv, 1760, 164, pi. 16, fig. 1. (Type, as fixed 

 by Stone, Auk, xxiv, 1907, 192, & Trogon viridis Linn8eus=T'. strigilatus 

 Linnseus.) 



Aganus ^ Cabanis and Heine, Mus. Hein., iv, Feb., 1863, 184. (Type, by 

 original designation, Trogon viridis Linnaeus.*^) 



Rather large Trogons, most like Curucujus in structure but differ- 

 ing in smaller size, more strongly graduated tail, with rectrices more 

 truncated at tip, much white on lateral rectrices, and under parts 

 yellow or (in one species only) reddish orange. 



« Three specimens. 



^ "Type remains the same," i. e., as given in the American Ornithologists' Union's 

 "Check List of North American Birds," second and revised edition (1895). 



c "Von dj-avSc (freundlich, angenehm)." (Cabanis and Heine.) 



d Not Aganus braccatus Cabanis and Heine, as given in Cat. Birds Brit. Mus. (xvii, 

 440), since the authors expressly say that the most typical species ("deren typischter 

 Arten") is T. viridis. 



To what group the generic name Earpaleus Cabanis and Heine (Mus. Hein., iv, 

 1863, 185, footnote) was intended to apply can not be determined, no species being 

 mentioned nor character given. In other words, the name is a nomen nudum.
