I had formerly thought this Bogota bird might be the šame as 

 the Central American E. hirundinacea, but I have lately obtained 

 other specimens, and find that such is not the case. The upper go- 

 louring of this bird is not of the pecuUar green shade wbich existsin 

 the true hirundinacea, and the yellow head, instead of being eonfined 

 to the frontai half and terminated by a straight line, extends further 

 back and is posteriovly rounded. The bill of this bird is also thicker, 

 broader and stronger, and shows more approach to the true Boliviao 

 laniirosti'is. 



I am not now certain whether it is this species or the hirundinacea 

 to which the Baron de la Fresnaye has giveu the MS. name forti- 

 rostris.

 I had not very good specimens of this bird when I described it in 

 P. Z. S. for 1854, and the figure there given -vvould suit better my 

 Euphonia crassirostris. M. Salle', howeTer, has lately brought some 

 beautifully prepared skins from Southern Mexico, which have enabled 

 me to determine the species more satisfactorily. 



I have seen specimens in which the white belly-spot, which is per- 

 haps produced by abrasion of the feathcrs in the most adult birds, 

 was scarcely apparent.

The Bogota birds have the bill rather stronger and the yellow 

 on the head more extendcd than the specimens from the Amazons.
