so long gone by that name,
TAPES. 355
that it would be unadvisable
to change it. It is probably his V. lata. Dale called
it Pectunculus fasciatus ; and this name has the precedence
of all others. I will adduce a few out of the
numerous synonyms published by different authors :
V. edulis, Chemnitz ; V. rhomboides, Pennant ; V. Beu-
dantii, Payraudeau ; and V. virago, Loven. In its
younger state it appears to be the V. nitens of Scacchi,
but not of Turton.

Body thick, oblong, greyish, yellowish, or very pale bluish-
white, sometimes tinted with pink : mantle having wavy or
jagged edges, which project a little beyond the valves ; the
indentations or folds are stronger at the sides than in front ;
within the margin are a few scattered white tentacular papillae :
tubes nearly equal in length and diameter, the upper being a
trifle longer than the lower, but not quite so large and more
conical and contracted at the opening ; they vary in length
from being only one-half to quite as long as the shell is broad ;
the upper serves for excretal and the lower for alimentary
purposes; both are cylindrical or funnel-shaped, and joined
together until about one-fourth of the distance from the orifices,
where they diverge, the upper curved backwards and the lower
forwards ; they are closely wrinkled across, and the upper or
outer third portion is irregularly traversed with brown streaks
or hues; the orifice of each tube is tinged with brown of
various shades, red, orange, or flake-white, and fringed with
short finely ciliated filaments, those of the upper tube being
plain, and the other set arranged in a double row ; the inner
row consists usually of a few only, which are erect and longer
than the outer row, and branched or studded at their sides
with short points, like the gills of some iS'udibranchs ; the
outer row is twice as numerous, very much shorter, and folded
outwards; the edge of the lower orifice is considerably ex-
panded, like a bell, when the animal is feeding :
