Lesson, who first described this species under the name of Ornismya duponti, was 
also the author of two of its synonyms, O. zémés and O. celestis, and referred in each 
case to the plate accompanying his first description. 
According to de Oca? 7. duponti is found during the summer in the vicinity of 
Jalapa and Coatepec, and it also occurs, though rarely, in the Valley of Mexico. We 
have no specimens from the latter locality, but from Jalapa and its neighbourhood 
we have several shot in the months of May and June by Mateo Trujillo. Mr. Richard- 
son secured specimens in January on the Volcan de Colima, and Mrs. Herbert Smith 
an interesting series of nicely prepared specimens on the Sierra Madre del Sur in 
August. 
The species has long been known as an inhabitant of Guatemala, but we only met 
with an occasional specimen during our stay in that country, and only in the depart- 
ment of Vera Paz. Mr. Richardson, however, seems to have found it in numbers near 
Santa Maria, in the department of Quezaltenango, whence he sent us many specimens, 
all of them shot in the months of August and September. 
The same collector also met with it in the mountains near Matagalpa in Northern 
Nicaragua 1° 1, 
This singular bird has no near ally, the peculiar shape and coloration of the tail 
rendering it quite unlike any other member of the family.
