neath it are fometimes feen {mall fcattered whitifh 
fpots. The eyes are fituated on each fide the back 
of the neck, internally, near the margin; and are 
pretty remote from each other. Each confifts of a 
tranfverfe, oval brown fpot, on which is placed in- 
wards an infundibulum or inverted cone of an ob- 
Ícurely-teftaceous color, receiving a hyaline fpherule 
refembling an air-bubble. The trunk from the eyes 
to the tail is nearly cylindrical; rounded behind on 
the back-part, and only connected with the tail at 
its bafe: it is f{mooth and without fpots; but be- 
neath, near the fin, is fpotted with white. The 
whole abdomen is rough beneath: before the fin: is 
feated a double facculus, (perhaps the ftomach ?) it 
is ovate, pendulous, hyaline-fpotted. The vent is 
feated near the ligament of the tail. In fome fpe- 
cimens, near the vent, at the end of the body, is a 
globofe whitifh nucleus, fmaller than a lentil. The 
tail is vertical, an inch long, connected to the body 
in front, (but beneath it), byalong neck: it is tri- 
angular, with the angles rough, and has four acu- 
leated lines on each fide, and is terminated on each 
fide by a femi-cordate, horizontal pinnule four 
times fhorter than the tail, and projecting beyond 
its tip, where its edge refts on that of thetail. The 
fin is fituated beyond the middle of the body, and is 
orbicular, an inch in diameter, compreffed, thick- 
ened at the bafe, and affixed to the white laminz of 
the trunk, which are crenated on each fide. Be- 
neath, in the margin, is another pinnule, which is 
bell-fhaped, hyaline, and affixed by a middle point. 
It is a native of the Mediterranean and. Archi- 
pelago.
