Habitat, Yucatan. Type in my collection. Obtained by Mr. 

 Geo. F. Ganmer, in compliment to whom I have named it. 



Mr. Ganmer sjDent three years in Yncatan ; he made large 

 collections in ornithology and other branches of natural history. 

 A full series of his birds was purchased by the University of 

 Kansas, and it is to be hoped that a catalogue of them will be 

 published. 



Mr. Gaumer wrote me that he had taken full notes of all the 

 species, whicli he expected to publish when the names of those 

 sold to the University of Kansas were determined. I purchased 

 the remnant of his collection, in which were the birds now 

 described.
