The typical specimen of Peristera mexicana (=P. albifacies) is in the British 
Museum. It was not described by Gray, who, after the manner of the period, published 
the name in his ‘ Lists’ of Gallinz and Columbe, considering this sufficient. The 
example in question is much decayed and seems not to have been properly preserved ; 
all the feathers of the head have perished, and it is impossible to identify this skin 
with any special race of Geotrygon. 
Count Salvadori!! has already drawn attention to the difference between Mexican 
specimens and those from other parts of Central America, and it is certain that the 
former have, as a rule, greyer heads than those from Guatemala and Nicaragua. He 
writes :—‘'The Mexican birds are much more grey on the occiput, where the median 
patch, instead of being golden-purple, is purple-grey; the transition, however, is so 
gradual that I have not been able to separate the two forms.” Our own examination 
of the large series in the British Museum confirms Count Salvadori’s conclusion. 
Several specimens from Coatepec, Vera Cruz, have a dull plumbeous-grey head, 
darkening somewhat on the occiput. We have in our collection similar examples 
from Danli in Honduras, the Volcan de Fuego and the Sierra de las Minas in 
Guatemala, and from Matagalpa in Nicaragua. Others with a white forehead and a 
vinaceous occiput are in our possession from the Volcan de Fuego, Choctum, Atitlan, 
El Rincon, and San Martin in Guatemala, and from San Rafael del Norte in Nicaragua,
