disposition for which so many of the tribe are remarkable, 
admitting of a near approach, particularly when engaged in 
feeding, and is therefore easily killed. Its voice is strong 
and harsh. The colour of its eggs remain undescribed. 
PiLate 94*. Represents an adult bird of the natural size. 
Bill stout, measuring from the forehead to the tip one inch 
and three quarters; wax-yellow at the base, passing to- 
wards the point into ochre-yellow. Orbits of the eyes 
red. Legs black, with the tibize feathered nearly to the 
tarsal joint. Hund part of the tarsi covered with rough 
scales. Membranes of the toes deeply scalloped. Hind 
toe short, with a strong nail. Entire plumage pure 
snow-white. Wings, when closed, extending beyond 
the tip of the tail. 
In the young state, the forehead, region of the eyes, and 
chin, are blackish-grey. Back, scapulars, and wing-co- 
verts, white, spotted and barred with brown. ‘The ends 
of the primary quills, and tip of the tail, are barred with 
the same. As the bird advances in age, the brown spots 
and bars gradually decrease at each moult, and it is 
supposed to be perfectly matured in two years and a 
half.
