" The sliouldcrs bluish-purple ; head, neck, back, and wing coverts very dark 

 purple, becoming of a bronzy hue on the lower part of the back and rump, Avhere: 

 also the feathers arc fringed witli metallic gAss-green, most conspicuous when the 

 bird is viewed from b(>hind ; tail very dark bronzy-purple ; wings purplish-brown ; 

 on each side of the chest a lunate mark of white ; the remainder of the under 

 siirface very dark purplish-brown ; the feathers of the throat edged with gray, 

 under tail coverts buff." (Gould, 1. c.) 



This is most probably only a dark variety of B. icilsoni. See my remarks in tho 

 Ibis (1. c).

This bird was referred to by me in the Ibis for 1876, but no name was given to 

 it. I now describe it more particularly. Although in its general plumage it is 

 like the B. prunelli, the coloring of the throat is very different, approaching that 

 of the B. wUsoni.
