^ Three specimens, all from Guatemala. 



^Five specimens; four from Guatemala, one from Jalapa, Vera Cruz. 



'I am unable to state whether there is any difference between Mexican and Guate- 

 malan exami)les of this species, the only specimens of the former that I have seen 

 being cage birds, and not in proper condition of plumage for satisfactory comparison.
