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 foregoing 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.
