swift, direct flight. Two females taken on November 16 were shot 

 at a lagoon where a number had come in to water about 9:30 a. m. 

 Others were recorded on the two days following. 



Peters " has pointed out that the species auriculata, formerly placed 

 in Zenaida, agrees with Zenaidura in having 14 rectrices and belongs 

 properly in the latter genus. The doves included in Zenaida have 

 only 12 tail feathers. 



As indicated in a recent review of auriculata by Mrs. E. M. B. 

 Naumburg/- this species is one ranging widely over South America 

 and is separated into a number of geographic races. According to 

 Mrs. Naumburg's findings the specimens here listed under vinaceo- 

 rufa would be called rubripes, but with this treatment I do not agree 

 after examination of a fair series of specimens in the U. S. National 

 Museum. The material at hand from northern South America seems 

 properly grouped in the following categories: 

 Zenaidura a. vinaceo-rxjfa (Ridgway): 

 Reference given above. 



Grayer, less vinaceous below than the two forms that follow ; wing, 

 males 135.4-138.3 (3 specimens), females 127.0-133.6 (5 specimens). 



Grenada, Trinidad, Curagao to Margarita Islands, and Venezuela 

 (except western part) south to the Orinoco River, and the Guianas, 

 probably into northern Brazil. 



Zenaidura a. jessieae (Ridgway): 



Zenaida jessieae Ridgwat, Proc. U. S. Nat. Mus., vol. 10, Aug. 6, 1888, p. 627 

 (Diamantina, near Santarem, Brazil). 



Darker, deeper vinaceous below, tips of external rectrices paler than 

 in robinsoni. 



Region of lower Amazon River. 



Zenaidura a. robinsoni (Ridgway): 



Zenaida ruficauda robinsoni Ridgway, Proc. Biol. Soc. Washington, vol, 28, 

 May 27, 1915, p. 107 (Honda, Colombia). 



Like jessieae but deeper in color below, particularly on the under tail 

 coverts, tips of external rectrices decidedly darker, wing, males 

 129.8-134.6 (two specimens). 



Magdalena Valley, Colombia, probably to western Venezuela. 



Zenaidura a. ruficauda (Bonaparte): 



Zenaida ruficauda Bonaparte, Compt. Rend. Acad. Sci. Paris, vol. 40, 1855, 

 p. 97 (Colombia).
