it places sometimes under the tiles of roofings, sometimes in the 



hollow of a tree. 



11. Synallaxis cegythaloides, vulg. Colilarga pingueridita, lays 

 in October or November from two to four eggs, in a nest badly 

 constructed, composed of straws and feathers, which it places 

 sometimes in the hollow of a tree, sometimes in the thatch which 

 covers the huts of the peasants. 



12. Synallaxis dorso-maculata, vulg. Trahajador, lays in Sep- 

 tember or October three or four eggs, in a nest skilfully made, 

 which it attaches to the reeds and rushes of the marshes of the 

 province of Santiago. 



13. Synallaxis sordida, vulg. Canastero, lays in September and 

 October two or four eggs, in a nest skilfully constructed, which it 

 places from three to six feet from the ground, in lonely places 

 which are covered with low and thorny shrubbery, sometimes 

 even on the Cereus quisco. This nest, a foot in length, is cylin- 

 drical, and composed entirely of little thorny branches. The 

 opening is in the side near the top, and forms a passage in the 

 upper part, which conducts to the lower part, which alone is pro- 

 vided with feathers to receive the young. 



14. Cinclodes nigrofumosus^ vulg. MoUnera, lays in the hollows 

 of the cliffs on the borders of streams. It collects water-plants 

 and builds of them a rude nest, on which it deposits two or three 

 eggs. The time of laying embraces the months of October and 

 November. 



15. Troglodytes platensis, vulg. Chercan, builds a large nest of 

 pieces of wood, straw, thread, wool, and feathers. This nest, 

 badly made and badly fastened, is not durable. It is placed in- 

 discriminately in the holes of trees, or of cliffs, in old walls, and 

 even under the tiles of houses ; it lays from September to No- 

 vember from three to six eggs. 



16. Scytalopus fusciis, vulg. Churrin, lays in October or No- 

 vember two eggs, in a nest rather badly made, which it conceals 

 under brushwood in the vegetable detritus, and which it ap- 

 proaches through a gallery or corridor, made in the same mate- 

 rials in which the nest is placed. The solitary and wild habits 

 of this bird make it not only difficult to find its nest, but even to 

 see it or to shoot it.
