These two species have been regarded by the Prince Bonaparte, in 

 his Monograph of the Columlldce, recently published (Conspectus 

 Avium, II, p. 84, Leyden, 1857), as forming a genus, to which he 

 applies the name, Zena'tdara. They are scarcely entitled to be 

 classed so high, nor so distinct, being, very probably, subgeneric only, 

 or a minor division of the genus Ectopistes. We find nothing recorded 

 by the naturalists of the Expedition in relation to the occurrence of 

 this biixl in Oregon, but the present specimens are highly interesting, 

 as demonstrating its very extensive range of locality.

According to Mr. Peale : 



"Common in the vicinity of Callao, Peru, in the month of July. 

 It has all the habits of the Ground Dove [C. passer ina),oi the Southern 

 United States, spending the most of its time on the ground, but fre- 

 quently alighting on bushes." 



Like numerous other birds of the family of Pigeons and Doves, that 

 described by Linnaeus as Columha minuta, has been mistaken by 

 authors, and confused with other species. The present bird, as stated 

 by Mr. Peale, is of common occurrence on the western coast of South 

 America, and is not rare in collections. It is undoubtedly the species 

 designated by the Prince Bonaparte as above cited, though intimately 

 related to others inhabiting various countries of South America.
