PANDORID^.
esteemed as S. siliqua. The flavour is said to be peculiar.
Poli mentions its being so acrid, that none but
the poorest would use this kind for food. The shell
differs from that of the last-named species in being more
regularly cylindrical,, deeper in proportion to its breadth,
and of an orange-grey instead of a purplish-green colour
the diagonal compartment is less marked ; the sides are
more truncated ; the anterior end is constricted ; and it
has fewer teeth.
Linne's description of >S^. vagina in the ^Mus. Lud.
Ulr. Reg.^ is peculiarly appropriate to this species,
although in the 12th edition of the ' Syst. Nat.^ he
appears to have imited with it an Indian species which
has been named S. truncata by W. Wood. Our species
(as a mollusk) is the Hypogcea tentaculata of Poli, and
(as a shell) the S. marginatus of Pulteney and Donovan.
The last-mentioned author said it was not the S. vagina
of Linne, but he gave no reason for saying so.
Family XYII. PANDO'EIDiE, Gray.
Body oval or oblong : mantle ha^-ing a slit on the anterior
side for the passage of a foot, and forming on the other side a
tubular sheath: tubes short, united nearly to their openings,
which are fringed : gills two on either side, each pair being
more or less united, long, narrow, and slightly curved : palps
corresponding in number -^Wth the gills, and triangular : foot
tongue-shaped.
Shell oval or oblong, inequivalve, pearty, gaping at the
posterior side, which is flexuous and elongated, and projects
upwards : healcs very small : cartilaf/e at the posterior side,
wholly internal, long and oblique : Mnr/e strong : teeth, either
a single cardinal in each valve, or an oblong plate, which is
attached only to the cartilage and partly covers the hinge:
pallial scar shght, and narrowly sinuated : muscular scars
small.
