 Habitat, Patagonia. (April.) Valparaiso. (September.) 



These birds are not uncommon on the dry rocky mountains near Valparaiso, 



and in the valleys of southern Patagonia, where a few thickets grow. They hop 



actively about the withered herbage and low thickets, and often feed on the ground. 



The hind claw is weaker and straighter than in most of the other species of this 



genus. 



4. Synallaxis maluroides. 



S. maluroides. D'Orb. $ Lafr. Voy de l'Amer. Mer. Ois. pi. xiv, f. 2. Mag. de Zool. 1837, CI. 11, pi. 22. 



My specimens were shot near Maldonado. Iris yellow; tarsi very pale coloured. 



This species, as well as some others of Synallaxis, Anumbius, and Limnornis, 

 live amongst reeds and other aquatic plants on the borders of lakes, and have 

 the same general habits. I will, therefore, here describe them. They all have the 

 power of crawling very quickly by the aid of their powerful claws and feet, 

 as I soon discovered when they were not killed at once, for then it was scarcely 

 possible to catch them. Their soft tail-feathers show signs of being used, but 

 they never apply them, as the Certhias do, as a means of supporting their bodies. 

 The tail-feathers were (at least during June) so loosely attached, that I seldom 

 procured a specimen with all of them perfect ; and I saw many (especially of 

 S. maluroides), flying about with no tail. All the species, or nearly all, utter an
