me in any part of the colony. 
It is like the common black hawk in every other particu- 
lar except the distribution of the white and black tints 
on the tail and its coveringfeathers. The tail is described as 
being black, white-tipped, and with a broad white central 
band ; while the covering feathers are black, with white 
edgings. As these same characters are certainly met 
with, more or less definitely marked, in stages of the 
common black hawk, it seemsto mealmost certain that the 
species here have been confounded ; and that whatever 
specimens have been referred to U. anthracina, have 
been nothing more than special stages in the life history 
of U. zonura. 
Two very beautiful species of the genus Leucopternis 
will be met with along the rivers, especially in the more 
wooded and secluded districts. They do not appear to 
occur on the cleared lands of the coast, nor on the low 
savannahs. Around the Indian cassava fields or deserted 
settlements, they will at times be found perching in the 
undercover or in the sheltered branches of the trees, 
jumping from branch to branch in search of grass- 
hoppers, locusts, cicadas and reptiles ; but I have never 
seen them on the exposed topmost bare branches, so 
much frequented by the generality of hawks. They are 
therefore not easy to secure, for one generally comes 
upon them suddenly and at close quarters, and almost 
before one is aware of it, the bird has jumped into some 
little thicket of branches and is lost from view. 
These birds will readily be recognised by the pre- 
dominance of white in their colouring. The entire under 
surface, and the head and shoulders, are white, while the
