7S Mr, Montagu's Description of Marine Animals 
grow to as large a size as in the Mediterranean sea, being some- 
times taken five or six inches in length, and when contracted 
would fill a large tea-cup. The beautiful purple dye which is dis- 
charged so copiously from this animal might, possibly, be turned 
to some advantage, if a method could be devised to fix it : we 
have seen several yards of a fishing-net stained with it under 
water ; and with difficulty it is washed off the hands. 
Doris pinnatifida, 
Tab. VII. Fig;. 2. 3. 
With the front rounded ; body slender, somewhat taper : co- 
lour gray, spotted with olive green : on the fore part two trumpet- 
shaped tentacula, terminated by a retractile filiform appen- 
dage : along the back are two rows of pedunculous appendages, 
longer than the diameter of the body; these are of a conic shape, 
each composed of five or six series of blue gray papilla?, marked 
with a black spot at their tips : the stem or centre part of the pe- 
duncle is a mixture of olive green and rufous brown. Fig. 3. is a 
magnified representation of the peduncle. 
Length, three-tenths of an inch.

orange ; these are disposed in several transverse rows : tentacula

tentacula : between the second and third row of tubercles are
