Found only near or above timber-line on the high volcanoes, but a very 

 rare bird and not often met with. The first one I took was on Irazu above 

 timber-line, not far below the summit of the volcano, where it was perched 

 on the tip of a scrubby bush and apparently alone. In April, 1907, while 

 collecting near timber-line on the Volcan de Turrialba, a small flock of 

 perhaps five or six birds came flying along the edge of a patch of trees, 

 alighting just over my head. One was secured, after which the remainder 

 disappeared. Another single male was taken the same day in a dense 

 thicket at the base of the crater.

Dr. Richmond has brought forward unquestionable proof that Cocornis 

 agassizi Townsend is the same thing as Cactornis inornata Gould, under 

 which specific name it must now be known, while Mr. Ridgway has 

 taken the genus from the Dicceidce and placed it in the family Frin- 

 gillidcB, where it evidently really belongs, being closely related to other 

 fringilline genera. This species is evidently found only on Cocos Island, 

 where, according to Mr. Townsend, it is the only really abundant land
