Adult male *. Back and scapulars blue-black, with a few stripes 

 of white on the lower back ; rurap and upper tail-coverts white, 



* Owing to the great dissimilarity of the plumage in the sexes, the male was 

 described as Vims wiUiamsoni, and for some time supposed to be a species 

 distinct from -S'. thi/roidcus, which was founded on the female.
