This beautiful bird is found in Southern Mexico, but throughout its range it is 
nowhere common. According to Sumichrast 1’ it is most frequently seen in the woods 
of the temperate and hot districts of Vera Cruz, but he does not record it from the 
Pacific coast. In Honduras Mr. Townsend procured a single specimen on the 
Segovia River in June ', and we have also an example obtained in British Honduras 
by M. Blancaneaux from the high wooded land about fifteen miles south of Cayo. 
When Sclater and Salvin? wrote their paper on the “Ornithology of Central 
America,” in 1859, the only known Guatemalan localities for this species were in 
the Pacific coast-region; since then we have found it at Choctum in Alta Vera Paz, 
on the Atlantic slope. On the Escondido River in Nicaragua Mr. Richmond 
procured a single specimen !°, and M. Boucard obtained but one example at Naranjo 
in April 4. 
Of its habits nothing has been recorded.
