The mufcle i is exactly fimilar to that o f the preceding ring,
and is crofted in the fame manner by the mufcle from the oppoiitc
fide o f the ring.
T h e e i g h t f o l l o w i n g R i n g s .
The mufcle f, in all thefe rings,- is very broad and ftrong;
the anterior fixture is at the intermediate inferior line, on the fold
o f the firft divifion of the ring; the other fixture is beyond the
lower divifion, with this difference, that at the loth and 11th
rings the fixture is at the lafl fold o f it’s ring; whereas in the
others it paffes over, and is inferted in the fkin o f the following
ring.
In all thefe rings the firft extremity o f g is faftened to the fold
which feparates the ring from the preceding one, and is parallel
to fj and placed at thé fide o f it.
The fix firft, g, are forked; that o f the fourth ring is very
much fo ; it does not unite till it is near it’s anterior infertion.
The longeft tail lays hold o f the following,, and is inferted near
the inferior line; the other inferts itfelf near the fame line, at
about the middle o f it’s own ring.
The'two laft, g, do not branch out, but terminate at the di-
vifions without reaching the following ring.
The mufcle h is placed at the fide of f, has nearly the fame
direction, and finilhes at the folds o f the ring.

The only gaftric mufcle left here is e ; it is placed on the intermediate
inferior line; in it’s direftion it feparates from it’s lateral,
and is inferted at the folds o f the upper divifion, and at the fub-
divifion o f this ring.

c is a large mufcle, with feveral divifions ; one placed under
(b) o f the preceding figure, one extremity is fixed near the lateral
line, at the fubdivifion o f it’s ring, the other to the foecal bag, a.
little lower than the mulcle b.

All the gaftric mufcles defcribed in the preceding figure disappear
in this, as well as all thofe lateral and dorfal ones whofe
letters are not found in this figure.

e f g are die gaftric mufcles, which are beft feen here.
e is narrow and long; it palfes under and crolfes f, one o f it’s
inferdons is at the lower line, the other is at the lateral, between
the fpiraculum and the neck.
