The shell generally known as the _Ach. virginea_ (_Bulla virginea Lin._) is
so common, that few collectors do not possess it. The varieties, however,
of this species are rare, and differ so remarkably in their colouring, as
to require illustration. Several kindred species of this family I have
already described; and on the same principle of establishing specific
distinctions from formation instead of colour, I shall now endeavour to
point out those characters which are common, more or less, to all the
varieties of this species, and which distinguish it from its allies. _A.
virginea_ may be known by the comparative shortness of the basal whorl,
which in general is broader than high; the margin of the outer lip is
entire, and sloping in an oblique direction; the aperture is wide, and
nearly round; the lower part of the columella takes a concave direction,
and between its base and that of the outer lip is a very deep notch. The
basal whorl is so broad that the shell, if placed on a table with its mouth
downwards, will remain erect.
Both these and the two next varieties are in Mr. Dubois' cabinet. Their
locality is unknown; but my young friend, Mr. Frederick Parkes, has
recently sent me shells of the common variety, found by himself near
Kingston, Jamaica.
