with the crown; throat the same; white rictal stripe faintly indicated, 

 rest of under parts dull brownish-green, with a few scattered yellow feathers 

 on the abdomen. In three specimens from La Hondura the moult has 

 been completed except on the crown, which is still largely clove-brown." 

 (W. E. C. Todd.) 



Apparently a rare bird in its range, which seems to be around the eastern 

 and northern slopes of the Volcanoes de Irazu, Turrialba, Barba, and Poas, 

 and in a few places in the Aguacate and Dota Mountains. It has been 

 taken only between the altitudes of 2,000 and 4,500 feet and in the almost 

 impenetrable jungle to be found at that elevation, especially on the Carib- 

 bean slope. Like all the finches of the Buarremon type, it is never seen 

 far above the ground, and seeks the darkest, gloomiest ravines for its 

 habitat. No nests were observed, although specimens were collected 

 during the breeding season. Further investigation will most likely prove 

 that the range covers the whole of the Caribbean slope between the alti- 

 tudes mentioned above, and perhaps the more humid portions of the 

 higher slopes of the Pacific.
