OREOPYRA CASTANEOVENTRIS CALOLAMA (Salvin). 
COSTA RICAN MOUNTAIN GEM. 
Similar to O. ¢. castaneoventris, but adult male with chin and 
throat always metallic violet or purple,* the feathers gray, instead 
of white, immediately beneath the surface. 
Young male.—Upper parts, including tail, as in adult female; 
chin and throat dusky, the latter with a few tawny-ochraceous 
feathers along middle line, the dusky color gradually passing into 
a Varying, in different specimens, from royal purple to phlox purple. 
> The supposed difference in coloration of the upper parts in females mentioned 
by Salvin (Proc. Zool. Soc. Lond., 1870, 205, 206) proves to be inconstant; in fact 
does not, so far as I am able to see, exist in even a considerable proportion of specimens.
