GRALLATORES.

Specimens in the collection are from Orange Harbor, Tierra del 

 Fuego. This species appears to be abundant on the western coast of 

 South America. It is related to Rallus ccKsius (Spix. Av. Bras. Plate 

 XCV), but appears to be larger, though specimens vary in measure- 

 ments quite considerably. We are acquainted with no figure of this 

 species. 



Very fine specimens of this bird are also in the National Museum, 

 brought from Chili, by the United States Astronomical Expedition, 

 commanded by Lieut. J. M. Gilliss, United States Navy. It appears 

 to inhabit the western coast of South America, from Chili to Patagonia.
