Arenicola piscatorium.
Blood-coloured Leodice, ([Leodice sanguinea].)
The antennated Annulata differ materially from those which are enclosed in a case; they possess, in addition to their antennæ, organs of motion, like the false legs of a caterpillar, and two or four well-formed eyes; they are all marine animals, and altogether they bear a strong resemblance to the scolopendra, or centipede.
Leodice sanguinea.
The species represented above was taken on the southern coast of Devonshire; it is the largest English species, extending sometimes to the length of fourteen or fifteen inches.
When the animal was in a glass of sea-water, the circulation of the blood through the bristle-like appendages on each side of the body was a curious object, and appeared to be effected at the will of the animal, but when it became sickly, the circulation was slower, and as soon as it expired all the colour from those parts vanished.
The mouth is large, and placed beneath, concealing most formidable jaws, or complicated fangs, which were put forward occasionally as the animal became sickly, or in the agonies of death. The figure beneath the worm shows the shape of this singular apparatus.
