«‘ This bird builds its nest on the summits of the loftiest trees, in 
flocks 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 they 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 ia the vicinity of the city of Men- 
doza, and are not found on the western side of the Andes :— 
Progne purpurea, Boie. Golondrina. 
«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 rose. It feeds 
on flies and insects, and inhabits the valleys of the Andes near Villa 
Vicencia. Bill blue; legs black; iris dark brown.” 
Turdus fuscater, D’Orb. Zorzal. 
“ Inhabits the vicinity of Mendoza. Iris brown. Sings equal to 
the blackbird of England.” 
Mimus tricaudatus, D’Orb. Calandria. 
“ This bird has a soft and melodious note; it sings when the sun 
is nearly lost in the horizon, which perhaps may give it a greater 
charm. Iris brown.” 
There is in the collection another species from this locality (Men- 
doza) calied Trenca, the technical name of which has not yet been 
made out. 
Rhynomya lanceolata, D’Orb. Turco.
