64 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. bahits 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. chloruauchenia ; lores and forehead white, merging 

 into pearly grey on the middle of the crown, L. chloruauchenia 

 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 f Biologia Centrali-Americana' (Aves, iii. p. 265) 

 Dr. Godman has separated G. albiventer Lawr., from Pauama, 

 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 betw-een the tw r o 

 forms. G. violacea has somewhat less of the lilac-bine 

 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.
