TRU 
from July to September. When drefled, it's 
flefh is red, and very delicious. On it's firft ap- 
pearance from the fait water, the falmon-loufe is 
found adhering to it's body. It has both milt 
and fpawnj but no fry has ever yet been difco- 
vered. 
The White Trout never exceeds one foot in 
length: the upper jav/ is fomewhat longer than 
the lower; in the firft, there are two rows of teeth, 
in the laft, but one; and on the tongue there are 
fix teeth. The back is ftraight; the whole body 
is of an elegant form; the lateral line is ftraight; 
the colour between that and the top of the back 
is dufky and filvery intermixed; and beneath the 
line, of an exquifite filvery whitenefs. The firft 
dorfal fin, which is fpotted with black, has eleven 
rays; the pedtoral has thirteen; the ventral and 
anal have nine each; and the tail is black, and 
much forked. 
Trout, Sea; the Salmo Trutta of Linnaeus. 
This fifh, which fome fuppofe to be fynonvmous 
with the falmon, bull, or fcurf Trout, an obfcure 
fpecies defcribed by Willughby, like the falmon, 
migrates up feveral of our rivers; where it fpawns, 
and returns again to the fea. It is thicker than 
the common Trout: the irides are filvery; the 
head is thick, fmooth, and dufky, with a glofs of 
blue and green ; and the back is of the fame co- 
lour, growing fainter towards tiic lateral line. 
The back is plain; but the fides, as far as the la- 
teral line, are marked with large, diftinft, irre- 
gularly fhaped black fpots. The lateral line is 
ftraight; the fides and belly are white ; and the 
tail is broad, and even at the end. The dorfal 
fin confifts of twelve rays; the pedloral of four- 
teen; the ventral of nine; and the anal of ten. 
The flefti, when boiled, is of a pale red colour, 
and extremely well flavoured. 
TRUFFLE-WORMS. A fpecies of fly-worm 
found in truffles, on which it feeds till it under- 
goes the common metamorphofis of fuch crea- 
tures. 
Thefe very fmall infects have two brown fpots 
near their hinder extremity, being the two pofte- 
rior ftigmata. They are wholly white, and very 
tranfparent; and the two black ftalks of their two 
hooks, with which they tear the fubftance of the 
truffle, may be eafily diftinguiflied. When they 
have arrived at their full growth, which is ufually 
in a few days, they quit the truffle, and go in queft 
of fome proper retreat, w here they may remain 
undifturbed during the time of their transforma- 
tion. In the fpace of twelve hours they are ge- 
nerally transformed into an egg-fnaped ihell, of a 
chefnut brown colour, and of the fame nature widi 
that of the blue fiefh-fiy. 
Thefe worms are in a manner peculiar to 
truffles. 
TRUMPE. An appellation by which fome 
Engiifts writers exprefs that fpecies of wliale co 
which Linnseus gives the name of the Phyfeter 
Microps, the blunt-headed cachalot. The Dutch 
call this fpecies the pot-whale-fi(h. 
TRUMPET-FISH, Scolopax, or Beilows- 
Fifli. In the Linnasan fyftem, a fpecies of the 
centrifcus; but, in the Artedian, a kind of the 
baliftes. 
This fmall fifh is commonly caught in the Me- 
diterranean. It's ufual length is about three in- 
ches; it's body is flat, and covered with rough, 
harfh fcales; it's fnout is extremely long, hard, 
ftraight, broad at the head, and narrow at the 
end, where it opens tranfverfely by means of a 
TUB 
membrane affixed to the under Jaw, which ftrvt^ 
to open and ftiut it at pleaiure. The eyes ar€ 
large; the irides are of a pale red colour; and at 
each of the gills there is a thin fin. Tiie anterior 
part of the body, which is formed into a fharp 
edge, has two bony fubftances inftcad of fins ; arid 
another below on the belly, which is lovv^er, and 
notched. Behind the anus there is a long fin^ 
reaching to the tail ; and on the back are two 
others; the one near the tailj and the other a long 
and large bony fpine, fet in a joint, and moveable 
at pleafure: before th.is there is another fine pric- 
kle; and behind it three more, which, taken roi- 
ledively, conftitute a kind of fin, 
TRUMPET-SFIELL, or WHELK; Euc- 
cinum. A large genus of fticlls: the characters 
of which are; that the fhells are univalve, and 
fhaped like a trumpet; that they have a diftind: 
and regular tail, ufually long, though fometimes 
fliort; a crooked beak; and the clavicle often ele- 
vated, though fometimes depreffed and conrabu- 
lated. 
According to Linn^ns, the charaflers of this 
genus are thefe: the inclofed animal is a Aug; the 
ftiell is univalve, fpiral, and gibbous; and the 
aperture oval, terminating in a fhort canal or gut- 
ter. He enumerates fifty-one fpecies.

TRUMPETER. An Englifh appellation for 
a particular fpecies of pigeon; the Columba Ti- 
bicen of Moore. 
This fpecies is nearly of the fize of the com- 
mon pigeon : it is pearly eyed ; of a mottled black 
colour; feathered down the legs and feet; turn- 
crowned like the nun, and fometimes like the fin- 
nikin. 
The moft diftinguifhing char?,6ler is a tuft of 
feathers at the root of the beak ; and, the larger 
this tuft, the m.ore highly is the bird efteemed. 
Thefe pigeons receive their nam.es from their 
cooing in fome refpefts imitating the found of a 
trumpet; but, in order to be often entertained 
with their melody, if we may credit Moore, thev 
muft be frequently fed with hemp-feed. 
Trumpeter is alfo an appellation given hv 
Pennant to the Pfophia of Linnsus, becaufe ot 
it's making a ftrong noife with it's mouth ; which 
it anfwers by a different found from it's belly, as 
if it proceeded from the anus, 
TRUTTACEOUS. The name of a ofenus 
of fifli of the trout kind, diftinguiflied frcrn all 
others by a fmall fat fin, without rays or nerves, 
near the extremity of the back. Some fpecics of 
this genus live only in frefli waters ; but others 
frequent both fait and frcfh, |nd are therefore 
called anadromi and catanadron^i. 
Truttaceous fifts are divided into two orders; 
thofe which have, and thefe which are deftitute of 
teeth. Of the edentulous kind, or fuch as have 
no teeth, are the lavaretus, ferra, thymallus, oxy- 
rinchus, and albula; and of the toodied kind cxrc 
the fahr.o, urnbra, trutta, carpio, &c. 
All truttaceous fifn are highly efteemed for the 
table. 
TKYGUM. An appellation by v.hich fome 
of the ancient ichthyolcgifts exprefied the pafti- 
naca marina, or fire-flaire «f the moderns, h is 
a fpecies of the ray. 
TUB-FISH. The EngliOi nam^e for a fpecics 
of trip;la, fometim.es called the flvinf2:-fifb. See
