GRAY-TAILED MOUNTAIN GEM. 
Precisely like the white-throated phase of O. castaneoventris casta- 
neoventris except in color of tail, which in the adult male is ash gray 
(usually darker terminally) instead of blue-black, the shafts of rec- 
trices whitish instead of dusky or dark grayish, the female with the 
dusky subterminal portion of the lateral rectrices much less well- 
defined, grading gradually into the dull grayish bronzy of the basal 
portion.
