This species was probably discovered by Boissonneau, in 

 Colombia, and was dedicated by him to Mr. Lafresnaye, who 

 had a fine Ornithological collection. Although the name of 

 T. lafresnayi, Boissonneau, ought to have the priority on 

 L. flavicaiidata, Fraser. I have adopted the generical name 

 of Lafresnaya, of Bonaparte, and the specific name of Fraser, 

 considering this generific name more honorific for the late 

 Baron de Lafresnaye. 



It is abundant in Colombia.
