to the extremity of -the tail. The bill is ftioit, a 
little arched on the top of the upper mandible, and 
of a blackifh colour; and round it's bafe there are 
fmall black feathers which form a bar reaching be- 
yond the eyes. This bar is bordered with white 
both above and below the eyes ; and on the top of 
the head there are feveral long feathers compofing 
a creftj which the bird is capable of erefting or de- 
preffing at pleafure. The head and neck are of a 
reddifh-brown colour; the breaft is whitilh; the 
belly and thighs are of a pale yellow; the covert- 
feathers beneath the tail are of a light colour; and 
the back is of a dark brown. The rump, as well 
as the covert-feathers on the upper-fide of the tail, 
are of a light afli-colour ; the wings on the upper- 
fide are cinereous ; but the greater quill-feathers are 
of a darker hue than the reft, though the margins 
of the exterior webs are of a light afh-colour. The 
inner webs of the three interior quills on each wing 
next the back are white to the tips; and feven or 
eight of the middle quills of each wing have fmall 
oblong unftuous fubftances depending from them, 
not unlike red fealing-wax both in colom* and con- 
fiftence. The tail is of a dark afh-colour, the tips 
of the feathers being of a fine golden yellow ; and 
the legs, feet, and claws, are black, and of the ufual 
conformation. 
The hens of this fpecies are lefs vivid in their co- 
lours than the cocks, and are deftitute of the red 
appendages at the tips of their wing-feathers. 
CHAYQUARONA. The Portuguefe name 
for a fifli of the turdus kind, caught on the Brazi- 
lian fhores ; more frequently called by it's native 
appellation, piraumbu. 
CHEGOE. An American infedl, called chique 
by the French, and negas by the Spaniards. It is 
very fmall, of a black colour, and generally found 
among aflies and other filth. It penetrates through 
the ftockings with facility, and generally lodges it- 
felf under the toe-nail, and the more prominent 
parts of the {km. At firft it produces a pain fome- 
what fimilar to the bite of a flea, and afterwards 
eats the flelh fo gently as only to occafion a flight 
itching; but by degrees tliis creature grows bigger, 
till at length it becomes of the fize of a large pea, 
when it produces nits which lodge round the parent 
infe6l ; and, if proper care be not taken, they in- 
creafe fo prodigioufly, that a putrefadlion of the 
furrounding flefli enfues, which produces malig- 
nant ulcers, and fometimes gangrenes. 
Thefe infefts not only infeft the human fpecies, 
but alfo monkies, cats, and dogs. The moft ef- 
feflual way to prevent their attacks, is to wear 
thick ftockings ; and to bathe the feet often, par- 
ticularly in fea-water. 
CHELIDON. An appellation given by many 
of the ancient Greeks to a kind of flying-fifli, called 
by fome authors milvus and hirundo ; and, by others, 
accipiter, or the hawk-fifli. It is properly a fpe- 
cies of the trigla; and is diftinguifhed by Artedi 
under the name of the trigla with the head a little 
aculeated, and a Angular member near the pe£loral 
fins. This method of reducing fifh to their true 
genera, and diftinguifliing them by their proper fpe- 
cific names, feems to be the mofl effeftual way of 
acquiring a perfed knowledge of them. The ar- 
bitrary names of milvus and hirundo convey fo im- 
perfect an idea of the particular fifh, that they 
might be as well applied to one fpecies as another; 
and accordingly we find two or three different forts 
of the trigla denoted by the inconclufive name of 
milvus. 
CHE 
CHELIDONIUS. The name of a certain 
fly, which fome authors call the fwallow-fiy on ac- 
count of it's velocity in flight. It is generally of 
a brown colour, with black prominent fhoulders, a 
black head, and fliort black antenna. The wings 
are filvery, and edged with black. It often con- 
tinues for a confiderable time on the leaves of 
plants; but, being very quick-fighted, it avoids 
every hoftile approach; and, from the length of 
it's flights, is not eaflly caught. 
CHELON. A fifli of the mullet kind, which 
ftronglyrefemblesthe comm.on mullet in it's general 
fliape, but it's eyes are more prominent, and it's 
head is fmaller. It has alfo two fide-lines running 
from the head to the tail, very evenly ranged, and 
placed at equal diftances; and it's lips are remarka- 
bly thick and prominent. 
CHERMES. A genus of four-winged infefls; 
the chara<fters of which are, that the roftrum or 
beak is fituated under the breaft ; that the abdo- 
men is mucronated or pointed at the hinder extre- 
mity ; and that the legs are formed for leaping. 
Thefe infeCts, which are in Englifla called bugs, 
derive their particular diftinftions from, the plants 
or trees on which they feed. Linneeus enumerates 
eight forts; namely, that of the elm, the maple, the 
beech, the elder, the fir, the willov/, the aih, and 
the nettle. Befides thefe, he mentions another fpe- 
cies, which is fuppofed to breed in the head of the 
ceraftes, or horned ferpent. 
CHERSYDRUS. An amphibious ferpent, 
fo called from it's living at firft in watery places, 
whence it receives the name of hydrus; after which 
it fliifts it's habitation, and remains on dry ground, 
and from thence it derives it's compound appella- 
tion of Cherfydrus. 
CHEV AIJER. A bird called by fome Eng- 
lifli naturalifts the horfeman, of which there are 
feveral fpecies. It is about the fize of a pigeon, 
and extremely well feathered. The bill is long, 
reddifh near the point, and black near the bafe ; 
and the head and legs are wholly black. The 
neck, back, and breaft, are white; but the remain- 
der of the upper-part is black. The wings are 
blackifh, and have a white tranfverfe line on each 
fide. It is called the Chevalier, or horfeman, be- 
cauie it ftands high on it's legs ; and Ibme fanciful 
authors have fuppofed that this circumftance gives 
it the appearance of being mounted on horfeback. 
It frequents lakes, meadows, and the margins of 
rivers, and wades into the water as high as the 
thighs. It's flefh is very delicate, and well fla- 
voured. In fome countries this bird is called crex, 
on account of it's voice, which feems to exprefs 
that fy liable; but it is never feen in England. 
Chevalier, Red, of Bellonius. The feet of 
this fpecies are of a yellowifli-red colour; the bill 
is fnort; the head and neck are of a dark afh-co- 
lour; and over the eyes there is a white line. The 
feathers under the wings are cinereous ; and on each 
fide of the temples there are^^^ black fpots. 
Chevalier, RED-LECcE^P^This bird is fome- 
times feen in this country, but not very frequently. 
It derives it's name from the colour of it's legs, 
v/hich are of a bright red. The top of the head 
and the neck are of a fine light brown; the bill is 
flender, near two inches long, of a reddifh colour 
at the bafe, and black at the extremity. The co- 
vert-feathers in the middle of the wings are black, 
but within two inches of the end of the tail they 
are brown, edged with white. This fpecies mea- 
fures near eighteen inches from the point of the bill 
to
