after he has fung in this manner by hiiiifelf for 
fome time, the reit obferving the mod perfeft 
filence, he lifts up his hand, and immediately the 
whole company joins in chorus. This intolerable 
yell is kept up, without intermiffion, till the fame 
monkey who gave the fignal for their beginning, 
elevates his hand a fecond time, when they all be- 
come filent in an inftant. He then exalts his voice 
again fingly, and fo finifhes the bufincfs of the 
affembly. 
Thefe monkies carry their offspring on their 
backs; and bound very nimbly from tree to tree, 
the young clinging fad to the bodies of their pa- 
rents. They are very fierce, and totally intraftible. 
There is alfo another fpccies confiderably larger j 
which Marcgrave pofitively affures us, often at- 
tack the negro women as they traverfe the woods, 
and even lie v/ith them bv force. 
GUARUGUARU. A fmall Am.erican frefii- 
water fifli, feldom. exxeeding one inch and a half in 
length, and having a very flender body. It is 
caught in lakes and ponds ; and it's flefli is ef- 
teemed very agreeable. 
GUATUCUPA. A Brazilian fifli which 
grows to tiie length of two feet. It's back is a 
little elevated; it's miOuth is fmall, and befet with 
fliarp teeth; and it has only one long dorlal fin, 
the rays of which are rigid and prickly. It is 
caught among rocks j and it's fiefn is extremely 
well-flavoured. 
GUATUCUSA. An American filh, ap- 
proaching to the nature of the coracinus of the 
Mediterranean; by fom.e called corvina. It is of 
an oblong fhape; it's back is a little prominent; 
it's belly is perfectly flat and even ; and it's ufual 
length is from twelve to tv/enty inches. 
GUDGEON; the Gobio, and Gobio Fluvia- 
tilis, of authors. In the Linnsan fyftem, the 
Gudgeon is a fpecies of the cyprinus ; and, ac- 
cording to the Artedian fyftem, the gobius is made 
the name of another genus of fiHies. This fifh, 
v/hich is generally found in gentle ftreams, is 
about five or fix inches long; the body is round; 
the fcales are fmall ; the back is brown, or olive- 
coloured; and the belly is v/hitifh. The irides 
are tinged with red, the gill-covers with green and 
filver; and at each corner of the m.outh there is a 
fingle barb. The tail is forked; and both that 
and the dorfal fin are fpotted with black. 
Thefe fifli grow to a much larger fize in fome 
rivers than in others ; and a few, we are informed, 
have been caught in the Cole, near Uxbridge, 
each of which vveiglied a whole pound. Their 
flefir is highly efceenicd, and dee:ried little inferior 
to that of fmelts. 
The Gudgeon bites very crgerly from the end 
of March till Michaelmas, and ma- be caught 
with a variety of baits : it may be drawn to any 
particular foot, by raking the bed of the river; a 
praftice frequently adopted, and always found fuc- 
cefsful. 
There is anodier variety of the frefli-water Gud- 
geon found in Germany, and there called a v/ap- 
per. It is of a m.ore tapering fhape than the for- 
mer, grows very fmall towards the tail, and it's 
colours are whiter and lefs fpotted. 
Gudgeon, Sea. See Goby, and Goget. 
GUEBUCU. An appellation given by fome 
authors to the fifh miOre ufually called the bicauda, 
a kind of fword-fiPn. 
GUFFER. A name given by Sibbald, and 
f)trie other writers, to the eei-pour. 
GUILLEM. A provincial appellation for the 
bird called by the generality of authors lommia, 
and in fome places the kiddaw and fea-hen, 
GUILLEMOT ; the Colymbus Troile of Lin- 
nsus. This bird is about feventeen inches long, 
and upwards of twenty-feven broad. The bill is 
three inches long, black, ftraight, and iharp- 
pointed ; and near the end of the lower mandible 
there is a fmall procefs ; the feathers on the upper 
part of the bill are fnort, and foft as velvet; and 
from the eye to the hind-part of the head there is 
a fmall divifion of the plumage. The head, neck, 
back, wings, and tail, are of a deep moufe-colour; 
the tips of the lefler quill-feathers are white; the 
entire under-fide of the body is pure white; the 
fides under the wings are marked with dufky lines ; 
and the legs are duficy. 
Thefe birds are found in amazing numbers on 
the cliffs which encircle feveral parts of our coafts. 
The Guillemot is a very fimple bird; and, though 
it's companions be Ihot one by one, it will not 
quit it's ftation. Like the auk, which it ftrongly 
refembles, it lays only one egg, fometimes of a 
pale blue colour, and at others white, fpotted, or 
elegantly ftreaked with interfering lines. It 
continues near the Orkneys during the whole 
winter. 
Guillemot, Black; the Colymbus Grylle of 
Linnaeus. This fpccies meafures fourteen inches 
in length, the expanfion of it's v/ings being twenty- 
two. The bill is an inch and a half long, ftraight, 
flender, and black ; on each wing there is a large 
bed of white; the tips of the leffer quill-feathers, 
and the inner coverts of the wings, are white; 
but, excepting thefe, the whole plumage is black. 
The tail confifts of twelve feathers ; and the legs 
and feet are red. In winter, this bird is faid to 
change to white; and a variety, fpotted with black. 
and white, is frequently feen in fome parts of Scot- 
land. 
The Black Guillemot frequents the Bafs Ifland, 
in Scotland; the Ifle of St. Kilda; the Faro 
Iflands; and, according to Pennant, the rocks of 
Llandidno, in Caernarvonfliirc. It continues al- 
ways at fea, except during the feafon of incuba- 
tion ; and is very difficult to be flnot, diving to the 
bottom at the leaft alarm. The V/elfn call this 
bird Cafgan Longwr, or the Sailor's Hatred, from 
a fuperftitious notion that it's appearance prognof- 
ticates a ftorm. It vifits St. Kilda in March; 
builds a fubterraneous neft ; and lays a fingle grey 
egg, fometimes fpotted with ruft and fpeckled with 
afli-colour. 
Guillemot, Lesser. This fpecies is feen on 
the Welfii coafts in the winter feafon, though not 
very frequently: it's breeding-place is unknown, 
as it has never been obferved on the rocks among 
congenerous birds. It's weight is nineteen ounces ; 
it's length is fixteen inches, and the expanfion of 
it's wings tv/enty-fix. The top of the head, the 
whole upper part of the body, the wings, and the 
tail, are of a very dark moufe-colour; the cheeks, 
throat, and lower fide of the body, are white; from 
the angle of the eye rifes a dufls;y ftroke, pointing 
to the hind-part of the head; the tips of the fe- 
condary feathers are white; the tail, which confifts 
of twelve feathers, is very fliort; and the legs are 
black. 
GUINEA-HEN; the Meleagris of fome au- 
thors, and the Numida of Linnsus. This remark- 
able bird in fome meafure unites the charadteriftics 
of the pheafant and the turkey, having the fine 
delicate
