N aturalists often assume the privilege of honouring individuals by naming remarkable species after
them, and although this practice is by no means to be commended, it is one which may readily be excused
when exercised in favour of those whose names are favourably known in the annals of Science ; in the present
instance it has been employed with singular appropriateness to do honour, through his wife, to M. Isidore
Geoffroy Saint-Hilaire, whose fame as a scientific naturalist is fainiliar to every one.
The Dorifera Ludovicias is remarkable for its short and robust body, the length of its wings, and the
straight, sharp, needle-like form of its bill, features in its structure which doubtless in some way modify its
habits; probably the peculiar shape of the bill is especially fitted for procuring its insect food from the
smaller kinds of tubular flowers, or from among the prickly spines of the Cacti, tribes of plants which
abound in the country frequented by the bird. Like many other rarities, this species is a native of New
Grenada, and particularly the neighbourhood of Santa Fé de Bogota, from whence alone I believe up to this
time specimens have been received; but whether it is a native of the upland or lowlaud districts of the
country is unknown.
All the examples that have come under my notice have been alike in colour, which induces me to believe
that there is no difference in the colouring of the sexes; but this of course is uncertain.
Forehead luminous metallic green ; crown of the head and nape coppery bronze ; back and wing-coverts
dark bronzy green, passing into bluish green on the upper tail-coverts; wings purplish brown ; tail black,
tipped with brownish grey, slightly on the two middle and largely on the lateral feathers; under surface
dark bronzy green with a tinge of grey; under tail-coverts grey, with reflexions of bluish green ; bill black;
feet fleshy brown.
The figures are of the size of life.
