Lki'Totila ruFaxilla dubusi (Bonap.). 

 Leptoptila diihusi Bp., Consp. Av. Ill: 1854: 74 (Rio Napo, Ecuador). 

 Leptotila ruf axilla dubusi Chapman, Bull. Am. Mus. Nat. Hist. XXXIV : 



1915: p. 370 (Foot of Mt. Duida, upper Orinoco). 



I have examined the single specimen (in the Am. Mus. collection), 

 from the foot of Mt. Duida, that has been identified as above by Chap- 

 man. It is probable that this race of ruf axilla is not found below the 

 great rapids of Atures in the Orinoco. 



ChaFmEpElia passERIna. GRANATIN a Bonaparte. 

 Chamaepelia granaiina Bp., Consp. Av. II. 1854. p. yy. 

 Columbigallina passerina granatina Berlepsch & Hartert, p. 48. 



N"ative name Potoquifa; "Carralera." 



Common throughout the savanna regions. Associates in small 

 flocks, but does not breed in colonies. 



Eye rose pink ; bill black at tip, Naples yellow at base ; feet flesh 

 white. 



Nests usually on the ground but occasionally in low trees. A 

 nest was found at Caicara May 2Q. 1905. It contained two fresh eggs. 

 The nest, a slight affair of slender twigs and grass stems, was on 

 the ground between the rocks on a steep hillside. The eggs are 

 elliptical ovate in form and measure 21.5 x 16 and 23.2 x 15.7 mm. 



This and the two succeeding species frequent the open savannas 

 and are exclusively ground feeders.

 Columbigallina rufipennis Berlepsch & Hartert, p. 119. 



Native name Potoquita Colorado. 



Common in the savanna regions. 



Adult male, eye orange yellow; bill dusky; feet pale reddish (pink). 

 An adult female had the eye yellowish flesh color, eye-lids lemon yellow ; 

 bill black at tip, dusky orange at base ; feet pale flesh white. 



The nest is on or near the ground and neither the nest nor the 

 eggs of this species are distinguishable from those of C. p. granatina. 



A nest containing one fresh egg was found at Caicara June 14, 

 1905. The nest, a slight platform of dead twigs and grass stems, was 

 placed between the stumps of dead leaf stems on the side of a -small
