Hab. Columbia. 
A native of Columbia, this species appears to be quite 
common in the vicinity of Bogota, whence numerous ex¬ 
amples come to Europe. It is the most brilliant species of 
the genus, and is closely allied to C. cyanocephala, from 
which it differs chiefly in the white under tail-coverts, and 
in the greater brilliancy of the sides of the neck and flanks.

Hab. Peru, eastern slope of the Andes ( Warszewiez ). 
I only know this form by the two specimens in Mr. Gould’s 
collection. It is certainly very closely allied to C. francice, 
with the blue of the crown extending further down on the 
nape than in specimens of that species ; but before being able 
to come to a satisfactory decision as to its specific value it 
is desirable to see more specimens. 
Peru is further south than any of the other members of 
this genus are known to pass; and it is not improbable that 
a different species exists in that country. The type spe¬ 
cimens were brought by M. Warszewiez; and although Peru 
has been fairly explored by several good collectors since his 
time, the bird has not again been met with.
