specimen, killed by M. Montes de Oca. 'This beautiful bird also bears a general resemblance in colour and
markings to those immediately preceding, but is distinguished from all o f them by its delicate light-green metallic
crown. For this new species I propose the name o f pallidiceps.
I f this little section be found to be composed o f four distinct birds, the species will stand th u s—H. longirostris
o f Trinidad and the adjacent portions o f the continent; H. Stuartee o f Bogota; H. Sclateri o f Costa Rica; and
H. pallidiceps o f Guatemala and Mexico.

This form, o f which the single species known has received the above generic appellation, differs in many
particulars from the preceding; the bill is less elongated and not so straight, while the tail is decidedly forked;
independently o f which, the gular mark is very different, the entire throat being luminous, while in all the species
o f Heliomaster the chin is black.

The Calliperidia Angela offers a still further departure from the true Heliomasters; for it has even a shorter bill
than the last, while its tail is much more deeply forked. I t is by far the finest species yet discovered. Its entire
body is clothed in glittering colours, and the bird itself must be seen and examined to obtain an idea o f its beauty.
The female, on the other hand, has the under surface o f the body smoky grey, differing in this respect from all the
others.

A single specimen o f a Humming-Bird, somewhat allied to the last genus, was killed by M. Warszewicz on the
sides o f the Volcano o f Chiriqui. It possesses so many remarkable characters that I was obliged, without a
moment’s hesitation, to assign to it a new generic appellation, that o f Oreopyra. Unfortunately the specimen was
so much injured by shot that I had much difficulty in giving a correct delineation o f it.

So different are the three birds found on the island o f Juan Fernandez, that it would not involve a great stretch
o f impropriety to assign to each o f them a separate generic appellation; I shall, however, retain them all under the
name o f Eustephanus. On an examination o f the plates o f the three species, it will be seen how remarkably they
differ in size, colour, and markings. I consider it a very singular fact connected with the family o f Humming-
Birds, that three species should be found on an island so distant from the mainland, and that two o f them should
be confined to this isolated spot, surrounded as it is by the wide waters o f the Pacific Ocean.

The
Genus P h /eo l /em a , Reichenb.,
is composed o f two Andean species, distinguished by their sombre colouring; for although both have a luminous
gular patch, and one o f them a glittering mark on the centre o f the crown, the brilliancy of these markings is not
so great as usual, and their tails are coloured unlike those o f any other group.
