74 Of ‘Palmipedes. Part' L 
before the Eyes. The nether Beak is compofed of 
three Bones. The two hinder, four inches long, near 
an inch high, and bended anfwerably to thofc of the up¬ 
per Beak. Their Edges are cut with deep Furrows. The 
third, at the end of the Beak, is hollow, above an inch 
long, near as high. Its Edges very lharp, and hard, and 
exceedingly convex or bended downward. Underneath, 
a round and fharp Pin grows out from it in a level towards 
the Skull, near an inch and I long. It was brought from 
the Indies. 
The Tape of this Bill fhews it to belong to a Bird of 
Prey, and as is moll likely, fome great Sea-Fowl ; which 
I will venture to call The Great Indian Gull. The ftrength 
ol the end oi the upper Beak is remarkable : as alfo are the 
fharp and hard Edges of the nether, and the Grooved 
Edges of both5 the ufe whereof fee in the Defcription of 
fome other Birds,as of the Jabiru and the Penguin. The up¬ 
per Beak feemeth to be compofed of fo many Bones, partly, 
that if a Fracture Ihould happen to one, it might there ter¬ 
minate, and the reft be fecur’d. 
The GREAT GREY GULL, or the Herring-Gull. La¬ 
ms grifeus maximus. Perfpicuoufly deferibed by Mr. Wil- 
lugh by. Who only omits to fay, that the upper Beak is 
bended upwards, as in the Bill above deferibed 5 and 
(which is obfervable) that the Edges of the nether are not 
lharp, as is ufual, but broad or expanded inward (and almoft 
60 wth. contiguous) as in the Pbeenicopter. They (a) are very nu¬ 
merous near Grave fend. 
Another GREY GULL, whereof the Rump, Tail, and 
upper part of the Wings are very white. Given bj Henry 
Whiftler Efqi. 
The TROPICK BIRD. So called, becaufe faid never 
to be feen but between the Trcpicks. Avis Tropicorum. Well 
deferibed by Mr. Willughby. He only omits the Denticu- 
lation of the edges of his Bill, or thofe fmall oblique In- 
cifions, which, from their inward refpect, are plainly made 
for the better retention of the Prey. Befides fome very 
fhort Feathers on his Tail, he hath two Quills above half a 
• yard long. 
Another TROPICK BIRD like the former. 
Another all over WHITE, except the fore part
