OREOPYRA CASTANEOVENTRIS CALOL.ffiMA (Salvin). 



COSTA RICAN MOUNTAIN GEM. 



Similar to 0. c. castaneoventris, but adult male with chin and 

 throat alwaj^s metallic violet or purple,^ the feathers gray, instead 

 of wliite, unmediately 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. 



b 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.
