ferent nature from the rest of the lip : tile colour of 
this fimbriated part or edge is variegated with black 
and yellow, which variegations are most conspicuous 
on the concave or under part: the membrane con¬ 
stituting the expanded part of the lip is composed of 
strong white and almost tendinous fibres : at the be¬ 
ginning of the head, where the lip commences, are 
two ear-shapec! tentacula, broad, flat, without any 
cavity, about six lines in length and four in breadth; 
and bearins; some resemblance to the cars of abound: 
no appearance of eyes can be distinguished, even by 
the assistance of a glass: the back, which commences 
immediately beyond the tentacula, is of a pyramidal 
figure or gradually lessening to a point: its length 
is about three inches and a half, and its breadth at 
the base something more than one inch: on each 
side the back down its whole length runs a series of 
white, fleshy, conical protuberances, the largest of 
which measure about five and the smallest two lines 
in length : besides these are also some scattered 
tubercles or appendices on the middle of tne back ; 
while on each side are certain swellings larger than 
the rest, and which are caused by the projecting 
parts of the abdomen which is oi much greater dia¬ 
meter than the back. 
This animal is principally found about the coasts 
of the Mediterranean.
