 Euphonia chlorotica Berlepsch & Hartert, p. 17. 



During the first expedition to the Orinoco, a series of Euphonia 

 from Altagracia, Caicara, Ouiribana de Caicara and Maipures were 

 sent to the Tring Museum and identified by Berlepsch and Hartert, 

 as pertaining to this species. At that time I seemed to have observed 

 many more examples of this species than I did of H. trinitatis, but dur- 

 ing the two last expeditions specimens of the latter species only have 

 been collected. 



No specimens of this species were found among the birds sent to 

 the American Museum by Klages either from the neighborhood of 

 .Ciudad Bolivar or from points on the Caura River.

Venezuelan common name "Fin-fin" or "Sin-fin." On the recent 

 expeditions I found this species common. 



A female in adult nuptial plumage (taken June I4th) is a rich 

 olive-green above, below, chrome yellow with sides of breast and 

 flanks a deep olive yellow. Females in what is probably the first 

 nuptial plumage are quite different from those in adult plumage and 

 resemble greatly birds in Juvenal dress. A female in what I con- 

 sider the first nuptial plumage, taken April I7th, is greyish olive- 

 green above; below, the throat, sides, flanks and under tail-coverts are 

 olive yellow brightest on the under tail-coverts, centre of breast grey- 

 ish, centre of abdomen greyish white. 



A male in Juvenal plumage, taken May 3Oth is greyish olive- 

 green above (of a lighter shade than the female of May loth) ; below, 

 breast greyish, abdomen white, sides of breast light greyish olive;
