Bourcier described this species from an example in the 
collection of the late Mr. Loddige, obtained at Zimapan, in 
Eeuador. It still continues a rare species, but few specimens 
having been sent to Europe. In form it is very similar to 
the other members of this genus; but the peculiar deep-violet 
throat will at all times serve to distinguish it. 
Genus CATHARMA. 


Bill longer than the head, broad at base, pointed at tip. 
Wings long, reaching beyond the centre of tail, which is 
extremely short and almost square. Throat-mark rounded, 
metallic.

As cited above, Lesson described this species, and figured 
a male almost adult and a young bird. It has been con- 
sidered by some authors to be the same as Calliphlox ame- 
thystina, either the young of that species, or an old female! 
(vide Gould, Intr. Troch. 8vo ed. p. 98). Upon what grounds 
this last supposition should have arisen, | am at a loss to con- 
ceive, as Lesson’s figure on pl. 28 1s evidently that of a male 
in nearly adult plumage. Unfortunately the artist has not 
coloured the tail properly, as he has represented it nearly all 
black, whereas the description says of it ‘‘ en dessus, les moy- 
ennes vertes et dorées, les latérales vertes et dorées a leur base, 
puis noires a leur extrémité, excepté les deux plus externes, 
qui sont terminées et ceillées de blane.”” This is lost in the 
figure, as the underside of the tail alone is given. Having 
lately come into possession of Lesson’s types of this species, 
I am able to state that it not only is a perfectly distinct 
species, but also represents an entirely new genus, most nearly
