his nether-end. Corystes Cassivelaunus is his name, which he is
said to have acquired from the marks on his back, which are
somewhat like a human face. "Those long antennae," says my friend,
Mr. Lloyd (6) - I have not verified the fact, but believe it, as he
knows a great deal about crabs, and I know next to nothing - "form
a tube through which a current of water passes into the crab's
gills, free from the surrounding sand." Moreover, it is only the
male who has those strangely long fore-arms and claws; the female
contenting herself with limbs of a more moderate length. Neither
is that, though it might be, the hole down which what we seek has
vanished: but that burrow contains one of the long white razors
which you saw cast on shore at Paignton. The boys close by are
boring for them with iron rods armed with a screw, and taking them
in to sell in Torquay market, as excellent food. But there is one,
at last - a grey disc pouting up through the sand. Touch it, and
it is gone down, quick as light. We must dig it out, and
carefully, for it is a delicate monster. At last, after ten
minutes' careful work, we have brought up, from a foot depth or
more - what? A thick, dirty, slimy worm, without head or tail,
form or colour. A slug has more artistic beauty about him. Be it
so. At home in the aquarium (where, alas! he will live but for a
day or two, under the new irritation of light) he will make a very
different figure. That is one of the rarest of British sea-
animals, Peachia hastata (Pl. XII. Fig. 1), which differs from most
other British Actiniae in this, that instead of having like them a
walking disc, it has a free open lower end, with which (I know not
how) it buries itself upright in the sand, with its mouth just
above the surface. The figure on the left of the plate represents
a curious cluster of papillae which project from one side of the
mouth, and are the opening of the oviduct. But his value consists,
