 of wearing spectacles : its irides are yellow, and 

 the pupil blue : the general colour of its plumage 

 is black : the wing-coverts have a white spot on 

 them, and in some specimens the under tail- 

 coverts are white : the tail itself is even at the 

 end. Found about Montevideo, and other parts 

 in the neighbourhood of the river Plata.
