 upper tail coverts, and sides of head to the level of the gape and below the 

 eye ; wings and tail similar, but less brilliant. Rump all round, external 

 edges of the central secondaries, entire under parts, including lining of wings 

 and axillars, white, with perhaps a faint ashy tinge, especially across tlie 

 breast ; the shafts inclined to be dusky, especially on the rump. Lores 

 gret-ni-sh dusky, bordered above by an obscure white line from base of bill; 

 the feathers of the hind neck and upper part of back, as well as those of thtt 

 forehead, with much concealed white. There is a trace of a narrow pectoral 

 collar of green on the sides of the breast, entirely interrupted below, however.

 extreme base». '' '• "vit.'.ji, /.n-j ■,-.■■'' --^ ;,:-.,..• ;lv.j,«.v':',_ ■-■.« 



The white of under parts appears perfectly pure on throat, middle 

 of belly, and crissum ; across the breast there is a shade of nsliy, a,s 

 al.so in the sides, most appreciable when the feathers are raised. On 

 the rump the dusky shaft streaks are most decided, and towards the 

 end involve the adjacent webs to some extent ; below they are 

 appreciable to a careful examination, except perhaps on the chin 

 and throat. There is a good deal of white at the base of tlie tail 

 feathers on ihe inner webs. There is also a gloss of violet, in some 

 aspects, on the wings and tail.
