The typical specimen of Peristera mexicana (=P- albifacies) is in the British 

 Museum. It vpas not described by Gray, who, after the manner of the period, published 

 the name in his ' Lists ' of Gallinae and Columbse, 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 



■^^rites : " 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 

 s^radual 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 Volean 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 Volean de Fuego, Choctum, Atitlan, 

 El Kincon, and San Martin in Guatemala, and from San Rafael del Norte in Nicaragua.
