Evidently a very rare bird in Costa Rica, and thus far found only 

 in the northeastern portion of the Caribbean lowlands, which is very 

 likely the southernmost extent of its range. There are three skins in 

 the U. S. National Museum from Jimenez, one J* and two 9 's, collected 

 by Alfaro and Carranza. I know of no others from Costa Rica, except 

 the two taken at El Hogar (three miles from Jimenez) by Mr. Lan- 

 kester and myself. These birds were taken in the heavy forest under 

 about the same conditions as those under which Pachyrhamphus cin- 

 namomeus is found.

This is another of the exceedingly rare birds of Costa Rica, but six 

 specimens ever having been taken (so far as I can determine) of which 

 four are in the United States, three in Mr. Bangs' collection and one 

 in the U. S. National Museum. While in Costa Rica I was shown a 

 beautiful adult male in the possession of Senor Jose Zeledon. I do 

 not know whether there are additional specimens in the Museo Na- 

 cional de Costa Rica. So far as now known, the Costa Rican range 

 for the species covers the high mountains only, while all of the skins 

 except one were taken on the Volcano Irazu proper, or in the moun-
