There is a faint tinge of purplish cream color in the white, especially conspicuous on the 

 breast and wings. The black of the back and belly is separated by white on the flanks. 



The tertials have a slight outward bend, but much less than in S. spectahilis. The frontal 

 process of the bill is elongated and rounded behind, and about in a line with the culmen.
