This genus consists of eight species, mostly peculiar to the Pata- 

 gonian Subregion, but extending some way northwards along the 

 line of the Andes like many other Patagonian forms. They are 

 terrestrial and rather Saxicoline in their habits. They vary much 

 in the length and shape of their bills, but are of a generally uniform 

 brown plumage.
