The members of the next genus, which in the regular order of succession comes 

 here, are birds of moderate size, and of a pleasing plumage, the chief colors of 

 which are green and Avhite. The genus comprises a large number of species, in 

 fact is one of the most extensive among the Trochilidae. Subsequent to the publi- 

 cation of Mr. Gould's Monograph of the Family, it has been known as the genus 

 Thaumatias, but as this term was applied by Bonaparte to a bird belonging to an 

 entirely diff"ercnt genus (viz., Trochihis tha%i,mantias, Linn.), and was, moreover, 

 preoccupied by Eschscholtz for a genus of Acalephs, it of course cannot be con- 

 tinued, and that of Agyrtria proposed by Eeichenbach is the one that has priority. 

 — There is no diff'erence in the plumage of tlie sexes, the females having as much 

 metallic coloring as the males. — For the discussion of the synonymy of the various 

 species, and their relative claims to such a rank, I would suggest that my article 

 published in the Ibis for January, 1878, upon the genus Thaumatias (Gould) 

 should be consulted.
