This bird frequents the dry stony hills of central Chile, on which only a few 
bushes and trees grow. It is closely related in habits and structure to the fore- 
going species, and appears to be its representative on the western side of the 
Cordillera ; hence I cannot but think the institution of the above two genera 
unfortunate. It is the “ Pitui ” of Molina, which name, I imagine, it derives from 
its peculiar cry. Molina states, that it builds its nest in holes in banks.

Peninsula of Tres Montes. Lat. 46° S. January. Captain King’s speci- 
mens were obtained at Chiloe, three degrees northward. I procured other speci- 
mens near Valparaiso. This bird therefore frequents dry rocky land, and damp 
impervious forests.
