This fine species inhabits Brazil : it is only six- 
teen inches in length : the beak is dusky ; its 
under part white : irides and orbits naked, and 
yellow : the general colour of the plumage black, 
with a gloss of polished steel : the head varied 
slightly with brown, and the wing-coverts with 
cinereous : the quills are greenish, with a spot of 
white near the tips : all the under parts of the 
body are white, varied with cinereous and pale 
yellow : the tail is greenish : the legs yellow. 
Described as a variety of the Blue Heron by 
Latham, but I think it possesses sufficient cha- 
racters to form a distinct species.
