Genus Lampropyeta, Reichenb.

The members of this genus (all figured in the work under the generic appellation of Cwligena) bear a general

resemblance to the last as regards their size and the lengthened and straight form of their bills; but their style of
colouring is very different, and, however much some naturalists may dissent from the idea of colour being regarded
as a generic character, I do think that it is of no little importance in this group of birds; for I find that every
distinct section or genus is distinguished by some peculiar style of plumage and colouring common to all the species
of which it is composed, and not found in the others. Thus the members of the present genus all bear a plumage of
a rather dull or sombre character with the exception of the lower part of the back, where it is luminous; but, as is
the case with the Agleactines, this luminous colouring is only to be seen when viewed from behind. All the known

species are found among the Andes, both on the northern and southern sides of the equator.

Habitat. New Granada.

In my account of this species, which is common in the neighbourhood of Bogota, I stated that the Bolivian
birds which appeared to be identical with it are much larger in size and darker in colour, and that I thought it
probable that they would prove to be distinct and undescribed; I still entertain the same opinion. I therefore take

this rtunit: ign i P
opportunity of assigning to this southern representative a specific appellation, but do not consider it necessary
to give a figure of it.
