Rhynchops nigra, Linn. Tijereta, or Scissor-bird.

 Phalacrocorax Brasiliensis ? Spix. Yeco and Pato del Diablo, or 



Devil Duck. 



" This bird builds its nest on the summits of the loftiest trees, in 

 jflocks of many thousands in the bay of Valdivia, near a place called 

 Los Guauros, south of the island of Mansera. It is impossible to 

 remain long in the place where the)'' build, owing to the offensive 

 smell occasioned by their dung, together with the putrid fish which 

 falls from the trees brought for their young. They obtain their food 

 by diving near the rocks along the shore, and are capable of remain- 

 ing long under water. Iris sea-green." 



Sula ? Piguero. 



" The Piguero inhabits the coast of Chile from the island of Chi- 

 loe to Copiapo. It is amusing to watch the motions of this bird 

 when flying over the surface of the sea. The moment it perceives 

 a fish, it folds its wings and falls with the rapidity of lightning into 

 the water, diving no doubt to a considerable depth, and often rises 

 with the fish in its mouth. The base of the bill, gullet and legs are 

 a beautiful light purple. Iris light brown." 



The following species are found in the vicinity of the city of Men- 

 doza, and are not found on the western side of the Andes : —

" This beautiful bird makes its nest in holes along the steep banks 

 of the rivers of Mendoza ; also in precipices near the thermal springs 

 at Villa Vicencia. Iris dark brown." 



Muscivora Tyrannus, Gray. Tijerata. 



"This singular bird is very pugnacious when setting; when on 

 the wing it extends its tail, which gives it a very singular appear- 

 ance. It takes its name from its tail resembling a pair of scissors. 

 Inhabits fields and vineyards near Mendoza, Iris dark brown." 



Lichenops (Fluvicola cyanirostris, D'Orb.). Virey. 



" This curious little bird receives its name from its note, which it 

 makes on the wing. It perches on the top of a bush, and on a sud- 

 den ascends for two yards in the air, and whilst so doing calls out 

 ' Vi-rey,' returning to the same twig from whence it i-ose. It feeds 

 on flies and insects, and inhabits the valleys of the Andes near Villa 

 Vicencia. Bill blue ; legs black ; iris dark brown."
