per chap of it is much longer than the under, and is {harp and ftrong; the gibbofity 
runs about one third of the length of the whole, beginning near the bafe 5 it is high-? 
eft in the middle, though not much fo, and it turns up at the point: the whole beak 
is elegantly variegated with a pale red, and a dufky white 5 the colours are in fuch 
equal proportion, and fo irregularly difpofed, that it is not eafy to fay which is the 
ground colour, and which the variegation. 
The body of this fpecies is thick, in proportion to it’s length ; the tail is moderately 
long, as the wings are alfo; when clofed, they reach within an inch of the tip of it: 
the whole body is of the fame uniform colour, which is a very beautiful one, and 
can no way be fo well defcribed, as by comparing it to that of a common black- 
beetle, on every part of which there is a fine and elegant tinge of blue fhining over 
the black ; the fame elegant {hade, but of a deeper blue, is call over the whole body 
of this bird : the legs are long and robuft, and the toes long, and armed with {harp 
claws. 
This is a native of Tartary and China. Barrelier calls it Hydrocorax csruleo-ni- 
gricans; no other writer has taken any notice of it: the beak is often brought over to 
us as a curiofity, and fometimes, thbugh very rarely, the whole bird. 
Buceros fubvirefcem. 
The greenifh Buceros . 
This is an extreamly beautiful, as well as lingular, bird ; the head is larger than in 
the former, but not fo remarkably large as in the firft defcribed fpecies: the whole 
bird is not bigger than our common crow, but the neck is fomewhat llenderer, and 
the legs longer: the head is depreffed at the crown, but not at all flatted at the fides: 
it has a very large quantity of feathers on it, and thofe on the hinder part are long 
and {lender, hanging a little way down the neck : the others are broad and {hort, and 
both are capable of being elevated, though not quite eredted at pleafure, and in this 
ftate the long ones form a kind of creft: the beak is about five inches and a half long, 
and in the largeft part is near three inches in diameter, the protuberance being larger, in 
proportion, than in any of the others: this is fixed down all along the upper part of 
the beak, except at it’s point, where it turns up, and points a little backward ; it is 
at leaft three inches long, and confiderably elevated above the reft of the beak, but is 
not higher in the middle than elfewhere : the whole beak is fomewhat curvated, but 
not much ; the point is fharp, and is formed only of the upper chap, the under ter¬ 
minating half an inch within it’s extremity : the colour of the beak is white, only that 
the ridge of the upper chap, and the point of the horn, are a little reddifh. 
The head is of a deep greenilh-caft, but with an admixture of black : the body alfo 
is of a green colour, as viewed in almoft any light; and yet this feems only a very 
ftrong tinge of the changeable kind, like the blue in the former a black, though much 
lefs diftinguiftiable, feeming, in reality, the ground colour, though this elegant tinge is 
fo univerfally and ftrongly diffufed over it. 
The tail is about three inches long; the wings are moderately long; when ex¬ 
panded, they fpread to a great extent, but, when clofed, they reach very nearly to the 
end of the tail ; both the wings and tail are of the fame green glofly hue with the 
body, but the black underneath is more diftinguifhable in thefe than elfewhere, and 
the green would be almoft univerfally allowed in thefe parts to be a fuperadded 
colour. 
The legs are very robuft, and moderately long; they are of a deep bluiih-black, 
and the toes are long, fcaly, and of the fame colour, and are furnilhed with very long 
and fharp claws. 
This fpecies is more rare than any of the former ; it is only found in China, and 
no where there, except in the inland counties: we had a fluffed fkin of it fent over
