If all genera were as well defined as that of Thalurania, the ornithologist would be far less perplexed than he frequently is with regard to the position of the species of which they are composed. All the members of this extensive group are characterized by great elegance of contour, the bill, wings, and tail being well proportioned, and in harmony with the size of the body; green and blue are the prevailing hues of the under-surface, while the crown and throat, and sometimes the shoulders, are ornamented with blue. The females are less elegant in form, and not so beautifully attired, all those parts which are green and blue in the males being, in every instance, I believe, of a dull grey.
The extent of country ranged over by the members of this group is very great: one, and one only, has been found to the north of Panama; the remainder inhabit all the countries southward to the latitude of Rio de Janeiro.

Habitat: Cayenne and GuianaPlate 101 Thalurania furcata Cayenne Wood-Nymph
Thalurania furcatoides (Gould)
Habitat: Para and the lower part of the Amazon
This bird is very like T. furcata, but is of smaller size, has a much less-forked tail, and the breast ultramarine-blue instead of purplish-blue. I have at this moment seven specimens before me, all of which are alike, and readily distinguishable from the Cayenne bird.
Thalurania forficata (Cab.)
Habitat: Supposed to be the neighbourhood of Para
Through the kindness of Dr. Peters, the Director of the Royal Museum of Berlin, I have had their specimen of T. forficata sent to me for comparison. It is certainly distinct from any of the species contained in the collections of this country: in size it is nearly the same as T. furcata; but its bill is rather shorter, its tail longer, more deeply forked, and of a purplish-black colour instead of steely-black: it differs from that bird also in having the blue colouring more extended down the back, approaching to that of T. Watertoni; the green of the throat is circumscribed and truncate below, as in T. furcata; and the crown of the head is black, but near the centre is a single small blue feather: I think it likely that this is accidental, as the bird appears to be fully adult: the under tail-coverts are black.

Thalurania verticeps (Gould)
Habitat: EcuadorPlate 107 Thalurania verticeps Green-crowned Wood-Nymph
Habitat: The Andes of Quindios
I have a specimen of this bird, collected by Warszewicz on the Cordillera of Quindios, which is precisely the same as the type specimen of the T. Fannyi of MM. Bourcier and Delattre. It differs from my T. verticeps in being considerably smaller and in having the abdomen purple-blue in lieu of cold prussian-blue.
