“This beautiful and rare species of Humming-Bird,” says Mr. Bridges, ‘‘is only found in the elevated valleys
of the Andes, residing amongst storms of hail, rain, and thunder, and in places where the naturalist would least
expect to find a species of Trochilus. It subsists more upon small flies than upon the nectar of flowers. On
examination of the crops I found them filled with flies, which they take before sun-down along the margin of the
mountain rivulets. Specimens were taken at Los Ojos de Aqua, province of Aconcagua, at an elevation of from
6000 to 8000 feet, and I saw them at least 1000 feet above that place. Iris brown.”’—Proc. Zool. Soc. part xi. p. 114.

Dr. Philippi met with this bird at Hueso Parado in Northern Chili, at an elevation of not more than 1000 feet

above the sea-level.

I now proceed to the

Genus Lampornis, Swains.

This genus comprises many species, some of which inhabit the West Indian Islands, and others the mainland.
The best-known among them, the Lampornis Mango, has a wider range than any of the others, as will be seen on
reference to my account of that species. hey are all distinguished by the harmonious colours of their ample tails,

which are even more beautiful in the females than in the males.

84. LAMPORNIS IRIDESCENS, Gould.

This is the bird from Guayaquil which I have spoken of in my account of Z. Mango as differing from the
Mangos of the other parts of America. The chief differences are a rather shorter tail and a glittering wash of blue
and green on the throat, instead of that part being velvety black; there is also a greater amount of green on the
flanks. Three specimens of this bird were killed and sent to me by Professor Jameson during one of his visits to
the coast.

Habitat. Guayaquil.
