Here, under this low-lying ledge of rock, is another shell, which in beauty perhaps excels even the gorgeous cockle. It belongs to a genus pre-eminent for loveliness, to which the name of the Goddess of Love has been assigned. This is the Banded Venus.[50] The most prominent and obvious character is that the shell-valves are covered with ribs, more or less strongly marked, which, instead of running fan-like from the beaks to the edges, as in the cockles, are concentric, being parallel with the edges. In this species these ribs are well marked, about a dozen in number, broad, flat, sharply defined, and nearly equally distant. They impart to the shell, which is very convex, and nearly round, an aspect of great strength combined with elegance. The colours, too, are very ornamental: broad bands of brownish lilac, varied with warmer tints, widening as they go, radiate from the beaks to the margins, relieved by a whitish ground. The hues vary in different individuals; the bands being sometimes rusty brown, or purple; and the ground yellow, or pale orange; and the contrasts are in some better marked than in others; but when fresh and unrubbed the shell is always a beautiful one.

SPINOUS COCKLE. BANDED VENUS.
The specimen before us is alive. I will drop it into this shallow pool in the rock. See, the valves are opening, and a large foot of a waxy whiteness, almost semi-pellucid, protrudes, thicker and more ovate than that of the cockle, but not capable of such elongation. The siphons, however, are proportionally longer; they are separate at their extremities, and project considerably from the shell.
But while we are gazing at the beauty of our little Venus, we become cognizant of the presence of another spectator. He has slowly come out from beneath the shadow of that long dark-brown leaf of Laminaria, that floats like a crumpled ribbon across the pool, and now rests on the tuft of Iridæa, that fine scarlet weed of leathery texture, that grows in the shaded corner. It is a Prawn;[51] and a fellow of noble dimensions. Is he too attracted by the fair shell? or rather is not his attention occupied by us? Yes; the latter is the true case; as you may discern by his long-stalked eyes, steadily staring upwards. He wonders what our two faces can mean; and, as we remain still, he ventures forth to take a fuller view.
