I nave not placed the Zrochilus Duchassaigni and Thalurania Celina of M. Bourcier among the synonyms of
the present species without due consideration and a careful comparison of the typical specimens one with
the other. The 7. Duchassaigni is a young male of the bird here represented which had not fully attained
the blue colouring of the throat. ~ The specific name Celina not having been given till a year later than
my own of ceruleogularis, it must give place to that term; besides which, the bird is not a Thalurania.

In form, this species and Sapphironia Goudoti are precisely alike, and these birds form a minute but well-
marked section of the Trochilide, the species of which are characterized by great elegance of form, as well
as by the beauty of their colouring: the under tail-coverts of both species are very conspicuous and extremely
pretty.

M. Verreaux has received this bird in tolerable abundance from Santa Martha ; my own were obtained in
Costa Rica, and M. Bourcier’s from Panama; it is clear, therefore, that New Grenada, Panama, and Costa
Rica are the countries in which this bird flies. Mr. Bridges informs us that it is found in the very streets
of the town of David, feeding on the Zamarindus Indicus and orange-trees, and that, like all other Humming-
Birds, it is very pugnacious, and constantly fighting with others of its species.

A marked difference is observable in the colouring of the sexes,—the female, although having the same
lengthened form as the male, being devoid of the bright blue of the throat and the fine green of the ab-
domen—those parts being greyish white; these, as well as other differences, will be readily perceived on an

inspection of the accompanying figures, or a perusal of the following descriptions :—
