This Geotrygon was first described by Prince Bonaparte in the second part of his 

 " Conspectus" from specimens obtained by M. Bourcier in the valley of Lloa in Ecuador, 

 and dedicated to its discoverer. It had, however, previously received the manuscript name 

 erythropareia in the British Museum, and is thus designated by Mr. G. E. Gray in his list of 

 Columbse, although no characters accompany the proposed new name. 



During his sojourn at Pallatanga, in 1858, Mr. Fraser obtained many specimens of a 

 Geotrygon^ which we believe to have belonged to this species, although they have been dispersed, 

 and are now beyond our reach, so that we cannot identify them positively. Mr. Fraser notes 

 the bill as black, and the " legs in front and toes above red." The bird was found on the ground, 

 and the food ascertained to be " fruit, and in one instance grasshoppers." 



Our figure is taken from the specimen in the British Museum, which forms the type of 

 Mr. Gray's Peristera erythroparew, and which was acquired by purchase of M. Verreaux in 1855. 



Several other species of Geotrygon occur on the southern continent of America besides the 

 present. — These are, as far as we are acquainted with them, — 



1. G. linearis (Knip et Prev.) : Knip. Pig. ii. t. 55, from New Granada. 



2. G, montana (Linn.), widely spread over S.America. — Chamicurros, E. Peru (Rauxwell): S. E. Brazil (Max. et 

 Burnt.): Paraguay (Azara). 



3. G. violacea (Temm.), Brazil, Bahia (Mus. Brit.). 



We have not yet met with examples of G. frenata (Tsch.) or G. melancholica (Tsch.). 



December, 1867.
