Boruca (Carriker). Fifteen skins. 



This species takes the place of the preceding on the Pacific coast of 

 Costa Rica. Its range is restricted, however, to the lowlands and 

 foothills of the region south of Puntarenas, not being found in Nicoya 

 or Guanacaste. It ranges to a higher altitude than does intermedins, 

 getting up to about 1,500 feet, though not in abundance. Its habits 

 are identical with those of intermedins, while its call is the same.

This is another of the remarkably rare birds of Costa Rica. The 

 type was taken by F. Carmiol at Barranca, April 10, 1865. Another 

 specimen collected by Carmiol at Buena Vista some time afterward is 

 in the British Museum. In 1882 J. Cooper took a single specimen at 

 Navarro, which, as well as Lawrence's type is in the U. S. National 

 Museum. The only other specimens which I know of from Costa 

 Rica are the one in Mr. Bangs' collection and the one in the Car- 

 negie Museum. From the localities cited above, the bird evidently 

 ranges over the lower portions of the plateau region and the higher 

 parts of both the Caribbean and Pacific slopes. There is some ques- 

 tion about the Barranca record belonging to the Barranca near Punt- 

 arenas, since it may possibly refer to another Barranca on the eastern 

 side of the plateau region, and if this is the case (which I strongly 

 suspect), the bird is confined to the Caribbean watershed. The single 

 specimen which I secured was taken in the dense humid forest in the 

 foothills at the base of the Volcan de Turrialba. The bird was perched 

 on a bit of underbrush about six feet from the ground, so that it is 

 evident that the species is partly arboreal, a fact which the structure 

 of the feet further bears out.
