|id pointed. Found adhering to rocks on the Pembroke- 
(hirecoaft, 
9. Lepas conoides, the conic acorn: (hell, conic, fmootli; 
valves pointed; aperture very (mall. Found at Weymouth, 
adhering to the L. anatifera, Shell (mail, reddifh; valves 
finely teffellate. 
10. Lepas teftudinaria, the tortoife-acorn : (hell plano¬ 
convex, with fix excavated (triate rays. This inhabits 
the Ocean, and is found commonly adhering to (hells; 
fomewhat refembles a globe cut off in the middle; white, 
fmoothifh, the lower aperture hexagonal and twice as 
broad as the upper; lid compofed of four triangular 
pieces inferted on a membrane. 
11. Lepas galeata, the helmeted acorn: (hell helmet- 
form, with a lateral aperture. Found adhering to the 
Gorgonia verrucofa and ventilabrum ; (hell boat-fliaped, 
fmooth, with a rhombic aperture. 
ii. Lepas palmipes, the palmated acorn : (hell ereff, 
conic; the valves palmate at the bafe. Shell white, a 
little depreffed, fize of a large pea, fmooth ; valves four 
to fix, divided as far as the middle into five or fix feg- 
ments; lid four-valved, oblique. Inhabits the Ocean. 
13. Lepas tulipa, the tulip-acorn: (hell fubcubic, 
fmooth ; lid acute and tranl'verfely ftriate. Inhabits the 
Northern Ocean. 
14. Lepas borealis, the northern acorn: (hell eredl, 
fubconic, aperture quadrangular, operculum acute and 
tranfverfely ftriated. A new fpecies, recorded by Dono¬ 
van. A few fmall clutters, with forne detached fpeci- 
mens of this curious fpecies, were difco.vered about 
the year 1800, attached to the bottom of the Warfpight 
(hip-of-war, when taken into dock to be repaired, after 
lying in the harbour of Portfmouth for a great length of 
time. Mr. J. Hay, of Portfmouth, foon after found two 
or three (hells of the fame kind, by dredging in Portf- 
mouth harbour. This fpecies appears to be very rare. 
15. Lepas mitella, the mitred acorn : (hell comprefied, 
eretf, and irregularly ftriate. Inhabits the Indian Ocean. 
White, covered with a dirty yellow (kin ; valves numer¬ 
ous, generally triangular, unequal, acute, feated on a 
common black peduncle, which is coriaceous, fcaly, and 
hollow within. 
16. Lepas fcalpellum, the lancet-acorn : (hell comprefied, 
thirteen-valved, fmoothilh, and feated on a fcaly peduncle. 
Inhabits the North Seas. Lefs than L. anatifera; valves 
refembling fcales, fix each fide, the longer one curved and 
inclofing the others; peduncle very (hort, with annular 
wrinkles. See the Helminthology Plate IV. fig. 4, 5. 
17. Lepas anferifera, the barnacle-fhell: (hell com¬ 
prefied, five-valved, filiate, feated on a peduncle. Inha¬ 
bits the American and Atlantic feas, and is fometimes 
found in a foflile (late. Peduncle pale faffron colour; firfi 
valve curved, fmooth and carinate on the back, the reft 
with diftant ftrise, each of the larger ones turgid towards 
the peduncle, with a wedged divergent end 5 the fmaller 
ones narrower and more pointed. 
18. Lepas anatifera, the duck-barnacle: (hell com¬ 
prefied, five-valved, fmooth, feated on a peduncle. Inha¬ 
bits mod feas, and is generally found fixed in clufters to 
the bottoms of velfels and old pieces of floating timber j 
generally whitifii with a blue caft, the margins of the 
valves yellow ; fometimes marked with a ray or two dot¬ 
ted with black; peduncle long, coriaceous, black, and 
very much wrinkled towards the (hell, and growing paler 
and pellucid towards the bafe, extenfile; fometimes, though 
rarely, red ; valves finely Ilriate; the two larger ones tri¬ 
angular; the two top ones nearly triangular and about 
half the fize; the other narrow, long, curved, rounded 
at the back, a little protuberant at the bafe, and inclofing 
the others. See the Conchology Plate XVI. fig. 10. 
The tentacula of thele animals are long, and pectinated 
like a feather, for which they were in fatt miftaken in the 
fixteenth century; and hence arofe the whimfical belief 
that the barnacle-fliell was the parent of the barnacle 
duck or goofe ! Nor was this the vulgar opinion only; 
it was fanCtioned by the grave details of learned natural- 
ids of that time, and particularly by Gerard, whole ob- 
fervations are generally noticed by authors in defcribing 
this fingular marine production. His words are thefe : 
“ What our eyes have feen, and hands have touched, we 
(hall declare. There is a fmall ifland in Lancafhire called 
the Pile of Foulders, wherein are found broken pieces 
of old and bruited (hips, fome whereof have been caft 
thither by (hipwracke, and alfo the trunks and bodies 
with the branches of old and rotten trees, caft up there 
likewife ; whereon is found a certain fpume or froth that 
in time breedeth unto certain (hells, in (liape like thofe of 
the mufkle, but (harper-pointed, and of a whitifii colour, 
wherein is contained a thing in form like a lace of (like 
finely woven as it were together, of a whitifii colour; one 
end whereof is faftened unto the infide of the (hell, even 
as the fifli of oyfters and mulkles are; the other end is 
made faft unto the belly of a rude made or lumpe, which 
in time cometh to the (liape and form of a bird ; when it 
is perfectly formed, the (hell gapeth open, and the firft 
thing that appeareth is the *aforefaid lace or firing; next 
coine the legs of the bird hanging out, and as it groweth 
greater it openeth the (hell by degrees, till at length it 
has all come forth, and hangeth only by the bill; in lhort 
fpace after it cometh to full maturitie, and falleth into 
the fea, where it gathereth feathers, and groweth to a 
fowle bigger than a mallard and lefler than a goofe, hav¬ 
ing black legs and bill or beake, and feathers black and 
white, fpotted in fuch manner as our mag-pye, called in 
fome places pie-annct, which the people of LancaPnire call 
by no other name than tree-goo/e ; which place aforefaid, 
and all thofe places adjoining, do fo much abound there¬ 
with, that one of the beft is bought for three-pence. For 
the truth hereof, if any doubt, may it pleafe them to re- 
paire to me, and I (hall fatisfy them by the teftimony of 
good witneifes.” Gerarde's Herbal , p. 1587, 8. For a full 
confutation of this abfurd notion, fee vol. i. p. 519. It 
will hardly be credited, that in the year 1808, a piece of 
wood picked up at fea encrufted with thefe worms was 
exhibited in London as a duck or goofe-tree. The (hells 
of the worms are affirmed to be duck-eggs ; and the ex¬ 
hibitor pretended to (how the foolifii multitude (at one 
(hilling a-head) the bills and feathers of the fowls emerg¬ 
ing from them ! 
19. Lepas dilata, the dilated barnacle: (hell comprefied, 
five-valved, and thin ; dorfal valve dilated at the bafe with 
an acute angle, and feated on a peduncle. The firft account 
we have of this fpecies was given by the late Mr. Ellis, 
from whom we merely learn that it is from St. George’s 
Channel. The fpecimen appears to have been fent by 
Mr. Ellis to the late duchefs of Portland, from whence it 
palled through the hands of the late Dr. Fordyce, and at 
his death came into the pofleffion of Mr. Donovan, under 
the title of Lepas figillatum of Solander. Unlike the ana¬ 
tifera or anferifera, though larger than either, the valves of 
this (hell are uncommonly thin and brittle, in a certain 
degree corneous, with the largeft lateral valve rather crum¬ 
pled in the ufual courfe of the ftriae, and marked tranf¬ 
verfely with oblblete rays. The (hell is likewife covered 
with a fine pale brown (kin, or epidermis. 
so. Lepas aurita, the eared barnacle : fheli membrana¬ 
ceous, ventricofe, feated on a tube, and eared; mouth 
eight-valved, toothed. Inhabits the North Seas. Pe¬ 
duncle long. 
21. Lepas pfittaccus, the parrot-barnacle: (hell hooked 
behind, fix-valved, wrinkled. Inhabits the coaft of 
Chili; hardly an inch long. The two larger valves re¬ 
ferable a parrot’s bill. Flefli white, tender, and very 
palatable. 
22. Lepas minor, the fmall barnacle: (hell reddifii, fix- 
valved, unequal; lid pointed. Inhabits India'. Shell 
marked with tranfverfe curved lines dotted with white. 
23. Lepas verruca, the warted barnacle; (hell hemi- 
fpherical.
