Mr. Charles Chubb on the 
Bill black ; tarsi and feet purple-red ; iris light brown. 
These birds belong to the species described by Count 
Salvadori as L. callauchen from specimens obtained by 
Dr. Borelli in the Province of Jujuy near Salta in Northern 
Argentina. L. callauchen belongs to the section of 
Leptoptila which contains L. bahiee and L. reichenbachi , 
having a deeper-coloured vinous breast than L. chloro - 
auchenia, of which Mr. Foster has also sent an example. 
From the latter L. callauchen differs in the more olive-green 
colour of the back and in the hind-neck being of a lilac- 
brown with slight violet reflexions, but no metallic green 
as in L. chloroauchenia ; lores and forehead white, merging 
into pearly grey on the middle of the crown, L. chloroauchenia 
being much darker grey on the crown, and white, not 
vinous, on the lores, sides of face, and ear-coverts ; sides of 
neck and entire breast dark cinnamon-vinous, paler on the 
lower throat and inclining to white on the chin; sides of 
body and flanks brown, the latter darker than the sides 
of the breast. This colour is scarcely perceptible in 
L. chloroauchenia.

In the ‘ Biologia Centrali-Americana (Aves, iii. p. 265) 
Dr. Godman has separated G. albiventer Lawr., from Panama, 
from G. violacea of Brazil. Cf. also Hellmayr, Nov. Zool. xiii. 
p. 384 (1906). I take the same view, as I can see some 
small but apparently constant differences between the two 
forms. G. violacea has somewhat less of the lilac-blue 
metallic gloss on the mantle, the forehead being pearly 
grey like the cheeks; the sides of the body have a sandy- 
buff tint. In G. albiventer the sides of the body are pink 
like the chest; the forehead and cheeks are pale vinous, and 
the metallic lilac-blue on the mantle is much more intense.
