Much larger specimens of this curious genus are however known on the British coasts, usually semi-parasitical on large fishes. Arctiirus bajfiiil, Sabine (Fig. 21), is another of the ' isopoda normalia'—normal to a certain extent in its structure, but very peculiar in its appearance and Kio, -0.—-A'l/' nasata, Norman.

Ai'cturus has, like Caprella, the habit of clinging to some foreign body by its claspers, and rearing up the anterior part of its body in a queer manner; but it has in addition a pair of enormously developed antennae, and to these the young cling by their claspers, and range themselves along like a couple of living fringes. Idotea (Arcturus) baffini was first described in the Appendix to Captain Parry's fourth voyage. This, or a nearly allied species, seems to occur also in the Antarctic Seas.
