58 THe BVO! Of KK 
nor could the fpiral windings of fome of them 
be feen 6. Moreover fome holes appeared be- 
hind the points, and alfo fome very fingular lit- _ 
tle grains of fand, fome of which were like- 
wife covered with the Fucus. Other holes 
were obferved likewife full of fofter purple 
coloured eminences. In fome of the hells a 
foft fea mud was found, in others a very hard 
one, the figure whereof was likewife {poiled by 
winding round the creatures. I likewife faw 
that a {ubftance adhered to the internal furface 
of one fhell in fuch a manner, that there was 
no void {pace either in the entrance or mouth 
in the fore part, or a little higher in the thell ; 
only where the tendons of the mufcles were 
feparated from the fubftance of the fhell. I 
obferved further, that Worms had pierced the 
fhells in fome places, ahd how fome of them 
had been broken and again joined together. 
Thefe fhells are ufually moft beautiful when 
the Hermits are {malleft in them, for they are 
not then covered. In fome other young ones 
of thefe, the periofteum appears of a very re- 
markable figure and beauty, where the fhells 
are not yet covered with the accreted matter ; 
as I have obferved in fome fmaller water Snails, 
in which the whole periofteam was very deli- 
cately adorned with briftly hairs. Let what has 
been hitherto faid of the {kin of thefe creatures 
fuffice. I fhall now explain the other parts of 
the Hermit, and that they may, be the more 
eafily underftood, I fhall divide the creature 
into four parts, the head, thorax, abdomen and 
tail, and {hall afterwards defcribe every thing 
remarkable in each. 
In the upper part of the head are feen two 
eyes, Tab. XI. fig. 1. ¢, and on one fide of 
the latter, two horns or antenne dd. Under- 
neath appear fome articulated briftly hairs, and 
alfo a mouth and teeth. ‘The eyes are oblong, 
fomewhat red, and in their aperture of a dark 
green colour: they are articulated on both 
fides with the head, by the affiftance of a cer- 
tain dentated ring, which confifts of a like fub- 
ftance with the fhell that furrounds the thorax 
and feet, and the other part of the eye is again 
articulated with the head. ‘This upper part of 
the eye is likewife very hard underneath and 
in the middle, but it is foft above, where the 
cornea tunica is placed. The horns are com- 
pofed each of three joints, whereof the largeft 
are thofe which are joined to the head on each 
fide of the eyes; from thefe the horns infen- 
fibly grow very fhort, and terminate as it 
were in {mall briftly hairs. In this thin and 
tender part of the horns I reckoned above one 
hundred and twenty very fine and delicate arti- 
culations, each of which was likewife adorned on 
each fide with two pair of fine hairs. In the larger 
Crabs thefe articulations are very diftin@ly con- 
{picuous, and when the Crabs are boiled, the 
horns may be divided into as many plain and 
fmooth rings as they have articulations of that 
kind. Between the firft and fecond joint of 
thefe horns of the Hermit, there is a {maller 
of Nv ASSP USR? Be 
or, 
rigid or hard appendage, beautifully adorned 
with briftly hairs. 
Between the horns, under the eyes, appear a 
beautiful pair of rough hairs, which confifts of 
three joints, whereof the upper one is the 
broadeft. Under thefe are feen the teeth, 
which are two little, hollow, white, oblong 
bones, and are furnifhed with ftrong mutcles, 
wherewith they are moved. Between thefe 
teeth is placed an external bone, by which the 
creature takes its meat, for which purpofe it 
has not only two arms or forcepse, f, but many 
articulated rough or briftly hairs, of different 
ftructures, which cover the mouth on the lower 
part. There are two very {mall, {mooth, 
broad, ruddy, fhaggy briftles, or rough hairs 
of this fort, each of which has one joint only. 
There is afterwards another pair of larger brif- 
tles of the fame conftruction, each of which 
has two joints. There is alfo a third pair, not 
{mooth or broad; but with thefe, on either fide, 
are two pair of fuch little parts likewife articu- 
lated, and every hair of this third part in the 
fame manner confifts alfo of two joints. The 
fourth pair is fomewhat fmooth and broad, and 
thefe are compofed of three joints; to thefe 
are alfo joined another pair, each hair of 
which has two joints. ‘There is in like man- 
ner a fifth pair, that are likewife double, that 
is, a larger one, compofed of four joints ; and 
the other, which is joined to the former, con- 
fifting of three. Liatftly, there are underneath, 
near the thorax, a very large pair of briftly 
hairs, like two legs, each of which confifts of 
fix joints, and has alfo on each fide a {mall 
part added to it with two articulations: So 
that computing the whole, there are here 
twelve pair of {mall parts beautifully interwo- 
ven with briftly hairs, which meet together 
when the Hermit fwallows its meat, as is ma 
nifeft from their ftructure and fituation. 
The thorax underneath is divided in the 
middle as it were by two teftaceous little 
bones, with which the two arms and the four 
fore legs, Tab. XI. fig. 1. gg, are articulated. 
And in order to fee this diftinly, it is neceffary 
to take the whole Hermit out of the thell, and 
to lay it on its back. Then four articulated 
briftly hairs are feen between the eyes. fig..11. aa; 
but the other briftly hairs before defcribed can- 
not be feen diftinctly, until after thefe are re- 
moved out of their places, becaufe they are 
covered by them. Near the eyes two horns 44 
come in fight, and afterwards two arms 
are feen very diftinctly, of which the left with 
its forceps c, is always lefs than the right d, 
though both are compofed of five teftaceous 
joints ; to the uppermoft of which is likewife 
joined by articulation a {mall part, which may 
be called a thumb, and from this the forceps 
of this creature have their origination. 
The four fubfequent legs ee confift of fix 
joints, which are alfo like the arms adorned with 
prominent notches, briftly hairs, ruddy {pots 
and furrows. And further, with the thorax 
are.
