In his ‘ Trochilinarum Enumeratio’ Dr. Reichenbach has figured a white-booted Racket-tail under the name of Steganura remigera, which, after a careful examination of the type specimen, I have no doubt is identical with this species, I have therefore placed that name among its synonyms. 183.

Bourcier is considered to be identical either with the S. Peruana or the present bird ; in all probability it was applied to the latter; and if this should prove to be the case, the term Adde, having been proposed prior to that of rufocaligata, should be adopted for this species. 186.

Perhaps the next in affinity, although not directly allied, are the members of the genus Lesbia, which are equally confined to the Andes, and fly at the same elevation as the Spathure. Like those birds, they are distributed along that great chain of mountains, throughout many degrees of latitude on each side of the equator. They may be regarded as among the most elegant of the Trochilide. Their long and deeply cleft tails would seem to indicate that they possess very great powers of aérial progression,—a remark which equally applies to the members of the genera Cynanthus and Cometes.
