In order to effect a correct determination of many species of this group of birds, I have found it absolutely
necessary to examine the typical specimens from which the original descriptions were taken,—a task of no
ordinary difficulty, distributed as they are among our own and the Continental museums, both public and
private. With regard to those described by M. Bourcier, I have had but little trouble, since they have not
only been freely submitted to my inspection in his own cabinet, but they have, in many instances, been
transmitted for this purpose to my own house; and his kindness has been especially serviceable with regard
to the bird here represented (Amazilia Devillei), as there are two or three species of this form so nearly
allied to each other that one description would almost serve for all, particularly if the minute points of
difference are not included there. Thus, by description alone, it would be very difficult to distinguish the
Amazilia Deville: from the A. Arsinoé ; yet these birds are really quite distinct—one (the Arsinoé) inhabiting
Mexico, and the other (the Dev://e:) Guatemala. In size, too, they are very much alike ; but the tail of Deville:

 

is by far the deepest and richest in colour, and has the beautiful fiery violet tints predominating over the
other red parts of the feathers, while the contrary is the case in Arsinoé. The wing in Devillei, also, is
much darker than in drsznvé, the base only of the primaries and secondaries being rufous chestnut, while in
Arsinoé somewhat more than the basal half is of this colour; and, finally, the green of the under surface
is much deeper, and extends further down towards the tail-coverts than in Devillev.

As I have before mentioned, the native country of the 4. Devillei is Guatemala. Some of the specimens
I possess were transmitted to me by Mr. Skinner, while others were received from Mr. Salvin, who collected
them at Duenas. Although I have said that the Arsézoé inhabits Mexico, and the Devillei Guatemala, I do
not believe that the two birds are strictly confined to those respective countries, but that they will pass the
border-line at one or other season of the year. I believe that the note attached by Mr. Salvin to Arsenoé
has reference to this bird, and not to that species; if so, I fear I may have inadvertently led him into the
error by giving a wrong name when he submitted his collections to me on his return from Guatemala.

It would be difficult to define in writing the minute differences which exist in the external appearance of

the sexes, the colouring being so very similar. In size, the female is somewhat smaller than her mate.

Head, wing-coverts, and back dark green; wings dark purplish brown, with a mark of rufous at the base
of the primaries and secondaries ; tail-coverts dark purple; tail rich fiery purple ; all the under surface
shining grass-green ; thighs thickly clothed with white feathers ; under tail-coverts pale bronzy brown ;
under surface of the tail purplish brown, margined and tipped with fiery copper ; bill black, except the base
of the under mandible, which appears to have been fleshy red ; feet dark brown.

The figures in the accompanying Plate represent two males and a female, of the size of life. The plant

is the Epidendrum lhinearifolium.
