names altogether. This bird is identical with an imperfect specimen 

 in the British Museum, which i- named "Perutera mezicana" in 

 the ' List of Gallinse,' &c. published iii 182 l ( p. 15), and " Perutera 



albifacies" in the ' List of Pigeons' published in 1856 (p. 55), but 

 not described. Prince Bonaparte, making a had guesa at whai the 

 bird in question might be, in his 'Conspectus, 1 part _', attributed 



both these names to another bird belonging to a dilVerent si ction, 

 Leptoptila (Consp. ii. p. 74. sp. 5), and nearly allied to the Lepto- 

 ptila fomaicetuu and /,. rufaxilla. In the " Addition- it C!orrections 

 au Coup d'CEil sur l'Ordre des Pigeons," published in the ( Ccmpt< - 

 Rendus'for Nov. 1856, the Prince, having discovered hi< error, pro- 

 poses to retain the name Leptoptila albifrons for the bird so de- 

 scribed in his ' Conspectus ' (hinting at the same time that it is the 

 same as Perutera braehyptera of the B.M. List), and states that 

 the present species of Geotrygon is identical with Cabanis' Geotrygon 

 caniceps. In this, however, as far as I can make out from the imper- 

 fect characters there given, he has fallen into two fresh errors. In 

 the first place, the true Geotrygon caniceps of Cuba(Journ. f. Orn. 

 1856, p. 110) appears certainly distinct from the present Geotrygon 

 albifacies. Secondly, the bird described by Prince Bonaparte as 

 Geotrygon chiriquensis in the same place (p. 21) is not my Geo- 

 trygon chiriquensis (P. Z. S. 1856, p. 143), but seems to be the pre- 

 sent bird, G. albifacies — distinguishable at once from G. chiriquensis 

 by the white terminations of the tail-feathers. For my knowledge 

 of this last fact I am indebted to M. Jules Verreaux, who has care- 

 fully compared specimens of both the species. 



The Geotrygon albifacies was obtained by M. Salle in the environs 

 of Jalapa, and has been received by M. Verreaux from the same 

 part of Mexico. I have taken my characters from a fine example 

 belonging to his collection.

 nithology of Southern Mexico gives as inhabiting that country —
