fame over each jaw, as in the Peregrine: the under parts from the 
chingyand reft of the fides of the neck, are dirty white, but the belly 
and thighs are marked with tranfverfe black ftreaks: the quills are 
dufky brown, and reach beyond the tail, which is croffed with feven 
or eight ftreaks of the fame; the extreme points of the feathers 
white: the bill is pale, with the tip dufky; the under mandible is 
not only fingularly notched, but is as it were cut off {quare at the 
end: the legs are yellow. 
This fpecies inhabits the lakes and borders of the fea, and rivers, 
which abound in fifh, on which it feeds, as well as crabs and fhell fith,. 
which it eafily breaks to pieces in the bill: it is feen too to fly 
after gulls, terns, and even the albatros’s, all of which give way to 
him; and it is probable that the true reafon is to oblige thofe birds 
to refign up the prey they have taken. This bird makes the neft 
on the rocks, when it frequents the neighbourhood of the fea, other- 
wife on the trees neat the rivers: lays four rufous white eggs. The 
male and female fit in turns, and the young brood often remains 
with the parents. till they have occafion to breed in their turn. 
Mr. Levaillant fuppofes this to have fome relation to the Tanas of 
the Senegal negroes, according to Adanfon; but it is much fmaller, be- 
fides, the fingularity of the under mandible being cut off fquare, is not 
noticed by him, and which could not furely have efcaped his obfer- 
vation had he feen it, therefore probably is not precifely the fame; nor 
can it be the Zavas of Buffon*, as it neither correfponds in colour 
nor creft, only in manners, as being fond of fifth, whichis. not uncom- 
amon to many other {pecies.
