-melanorhynchus, Sturm’s Edit. of Gould’s Mon. of Ramph., pl.

 

Tuts species was first characterized by Mr. Waterhouse (from a specimen belonging to the late Earl of Derby)
in 1839, four years subsequent to the completion of the first edition of this work, and during my absence in
Australia ; two years later Messrs. Sturm figured it in their edition of my Monograph under the name of
P. melanorhynchus, both those gentlemen and Mr. Waterhouse having selected the black colouring of its
bill, in which it differs from every known member of its family, for their specific appellation.

It is a typical example of that division of the family to which I have applied the generic term Andigena ;
it is, moreover, one of the most delicately coloured, and one of the most interesting species of the genus ;
from all of which, as above-mentioned, it differs in the black colouring of its bill, which is beautifully con-
trasted with the snowy whiteness of its throat; while the blue of its under surface is even more delicate
than in Z. lypoglaucus. It is a large and powerful bird, and the strength of its mandibles indicates that it
can use them with greater force than any of its congeners.

Mr. Miferhouse has remarked that the nostrils do not extend so far forwards, that they are hidden by
the feathers of the head, and that there is no longitudinal groove in front of them, as in other species of
the genus.

Farther than its occurring in most of the recent collections sent from | th
s it frequents in the great Andean Range. But little difference

her hand, they differ considerably in size,

Santa Fé de Bogota, nothing is

known respecting it; not even the localitie
is observable in the colouring of the birds sent to Europe ; on the ot
the smaller birds being probably females.

The figures are of the natural size.
