Larus cinereus capita et medietate alarum^ nigri - 
cantibus . Btafiii'mt 
The grey Larus, with the head and one half of the (IfJtttl. 
wing black . 
This is one of the larger fpecies^ the fke is about equal to that of otir common 
hen : the head is very large, and the neck fhort and thick : the eyes are fmall, and 
their iris is of a whitilh-grey : the ears are wide and confpicuous; the beak is an inch 
and half long ; it is nearly ftraight all the way to the extremity; but there it is crook¬ 
ed and {harp: the upper chap is yellow along the middle, but of a deep brown on 
the fides, and black at the extremity : the under chap is yellow throughout, and has 
a large protuberance on it’s lower parts. 
The head is black on the upper part; the neck and back are of a deep grey, and 
the breaft and belly" are white: the wings are very large; their covering feathers are 
grey, but the long feathers are all black half the way up from their extremities, and 
white in the reft, where they are covered by the {horter : the tail is moderately long, 
and is alfo white toward the bafe or root, but the lower part of it is black. 
The legs are long and robuft; they are of a dulky orange yellow, and the feet are 
webbed ; and the hinder toe is fhort, but it has a claw like the reft. 
This is a bird of South American origin, but we fometimes have the {kin ftuffed, 
and fent over to us. The Portuguefe there call it Gaviofa; the natives, Guacuguacu ; 
Marcgrave, and the others who have written on the Brafilian animals, have defcribed it. 
Larus, nigricans alts cinereisj pedibus rubentibus. fC&ttTJOtt) 
*The black Larus, with grey wings, and red legs. (JJttiU 
This is of the fize of the common pigeon, and has very little the appearance of the 
Larus-kind, on a general view, though it has, when examined, all their chara&ers: 
the head is large, and the feathers ftand fomewhat loofe upon it: the eyes are long, 
and of a piercing afpedt; their iris is of a yellowilh-hazei, and the pupil is black: 
the ears are large, patulous, and confpicuous: the beak is three quarters of an inch 
long ; it is moderately arched in form, and is very hooked at the point; it is all over 
of a deep black, except that the noftrils, which are oblong and narrow, arfe rather 
brown. 
The neck is Jfhort and thick: the whole head, the neck, and alfo the back, fhoul- 
ders, breaft, and belly are all of a coal black : the wings are very long ; when clofed, 
they reach beyond the extremity of the tail; they are of a very beautiful dark iron- 
grey : the tail is moderately long, and is of the fame iron-grey with the wings, only 
that it is black at the end. 
The legs are very {lender and fhort, they are of a beautiful fcarlet; the hinder toe 
is very fhort and inconfiderable, but it has a little claw on it. 
The male and female of this fpecies are no way to be diftinguifhed, but by an ele¬ 
gant white fpot, ‘which the male has under it’s throat. This fpecies has been fuppofed 
not a native of England, but I killed feveral, about four years fince, among the Bognor 
rocks on the Suffex coaft, and was informed, by the country people, that they bred 
there. Moft of the writers on birds have named it. Gefner and Aldrovand call it 
Larus niger; and Ray, Willughby, and others have continued the fame name.
