longer. All the upper part of the plumage is of a 

 delicate light grey, which slightly margins the true 

 and spurious quills, which are black : the fore part 

 of the neck and its sides, the ears, and as far as the 

 breast, is entirely grey ; much darker, in the male, 

 than the upper plumage, and ending abruptly on 

 the breast where it forms a curve and becomes 

 almost black ; all the rest of the under parts are 

 pure white. The female differs in having the breast 

 like the back, softening off on the chin and on the 

 body to white. The tail is black, the middle and 

 lateral feather on each side grey. 



Total length, 10 ; bill, from the gape, 1 ; wings, 

 5 J ; tail beyond, 2^ ; from the base, 5 ; tarsus, ^g.
