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. Yoy de l’Amer. Mer. Ois. pi. xiv, f. 2. Mag. de Zool. 1837, Cl. 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 1 saw many (especially of 
S. maluroides), flying about with no tail. All the species, or nearly all, utter an
