 The great grey GuIL Larus albo-cioereus torque cioereo. 



Numb. LXXXIII. 



ITS Weight was one Pound fourteen Ounces and a half; Length, from the Point of 

 the Bill to the End of the Tail, twenty one Inches and a half ^ its Breadth, when 

 the Wings were extended, fifty three Inches ; its Colour on the Back and upper iide of 

 the Neck were grey mixed with whitifii and brown ; the Feathers on the Back are 

 black in the middle and afli-coloured about the Edges ; the Rump Feathers incumbent 

 on the Tail are for the moft part white, only fpotted in the middle with brown -^ the 

 forepart of the Head, Throat, Breaft, Belly, and Thighs were white. 



Each Wing hath thirty Quill-Feathers of a dark brown, in fome black, the leiTer 

 Rows of wing Feathers were alfo brown ; the Tail is fix Inches and a half long con- 

 lifting of twelve Feathers, the outmoft Tips of the upper fide of which were white, 

 then fucceeds a crofs Bed or Bar of black of about two Inches broad, the under fide 

 is varied with tranfverfe Bars of a dusky Colour, 



The Bill is almoft three Inches long, all black, the upper Chap bending a little 

 downward and as it were hooked ; the lower, between the Angle and the Tip under- 

 neath, bunches out into a Knob; the Noflrils oblong, the Eyes grey, the Neck fliort, 

 the Head great, which in walking or ftanding flill it always draws down to its Shoulders, 

 as do alfo all other Gulis, fo that one would think they had no Neck. 



Its Legs and Feet are of an orange Colour ; the Claws black, that of the middle Toe 

 fliarp on the infide. 



It hath a huge Liver divided into two Lobes, a Gall annexed to the right Lobe, The 

 Stomach more mufculous than in carnivorous Birds ; the blind Guts fhort but little, yet 

 turgid and full of Excrements. 



The Cor7iip Men relate for a Truth, that this Bird is wont to perfecute and ter- 

 rify the Sea- Swallows, and other fmall Gulls fo long till they mute for fear; and then 

 catches their Excrements before they fall into the Water, and greedily devours them as 

 a great Dainty : but I rather believe, they take from them the Fifh which they have be- 

 fore taken, caufing them to caft it up out of their Stomachs, which example I have 

 feen in the Wejl-Iridies, of the Bird called the Man of War and the Booby ; which lafl: as 

 foon as he has taken a Prey, the other perfecutes him till he has thrown it up, which 

 he catches in the Air immediately.
