" This species differs from H. larvata in the grey forehead, 

 darker upper surface, and pale under surface, but especially in 

 wanting the beautiful coppery-red metallic gloss, which H. larvata 

 shows in certain lights on the occiput, nape, region of the crop, and 

 upper breast. By reflected light it shows on the occiput and nape, 

 and less distinctly on the sides of the neck, a greener coppery gloss ; 

 on the crop-region u slight gloss is seen only on the edges of some of 

 the feathers : ' iris violet ; naked skin round the eyes blue-green ; 

 feet bluish grey and brown-red ' " {Dr. Preuss).
