 species, which ought perhaps to be referred to a diiferent genus.

Opetiorynchos, Temm. Man. ciOni. i. p. Ixxxiii (1820) . . F. rufus.

This well-marked genus consists of some eleven or twelve species, 

 which are spread over South America from Panama to the Argentine 

 llepublic, but do not extend into Chili and Southern Patagonia. 

 They are clad in plumages of clear browns and white, and have 

 smooth tarsi with the. divisions of the scutes often scarcely apparent. 

 The enormous oven-like structures which they erect for nests have 

 caused them to be called " Oven-birds."
