" Iris dark red in males, dark brown in females, feet pink, 

 bill black." 



This series is rather puzzling. The males show a wide amoiuit 

 of individual variation, every shade of blue between the ultra- 

 marine of D. c. napaea and the deep purplish blue of D. c. ccere- 

 bicolor (of Bogot4) being represented. The lightest specimen, 

 no. 2006, from Noanama has the blue portions of the plumage of 

 exactly the same tone, and the mantle as well as the gular patch 

 as dull (greenish black) as topotypical Santa Marta skins, from 

 which it only differs by its smaller size and shorter bill. Next 

 come no. 2214 (Noanama), no. 564 (Jimenez), and the male from 

 Rio Oscuro, which are just a shade darker, more cobalt, with the 

 black of the mantle and throat deeper, less obscured by dull 

 greenish tips. Then follow ten specimens which have the plumage 

 more or less tinged with purple. Finally, three birds, nos. 2187 

 (Sipi), 508 and 541 (Jimenez), and a fourth from Paramba, N.W. 

 Ecuador, are quite as bright and deep purplish blue as Bogotili 

 skins.
