chi) ; Sicily (Pliilippi). Its southern limits comprise
the North Atlantic from the Boulonnais to the Lusi-
tanian coasts and Madeira, the Mediterranean, Black
Sea (Krynicki), and iEgean, at depths between 7 and 50
fathoms ; and the two varieties have a range of nearly
equal extent.
This elegant little shell can scarcely be mistaken for
any other of the Tellens above described. Specimens
in the
vary in having the strise more or less compact ;
young these are laminar on the posterior side.
It is the T. trifasciata of Pennant (but not of Linne),
T. vanegata of Poli, and T. subcarinata of Brocchi. This
and the following species have many characters in common
with Psammobia, and appear to form a connecting
link between the two genera.

Body shaped like that of T. clonacina, whitish and transparent
: mantle plain-edged and not fringed : tubes nearly con-
tiguous, although separate; incurrent tube bag-shaped, ex-
exeurrent much longer, very broad and dilated
tremely short ;
at the base, and then becoming cylindrical, four or five times
the length of the other tube ; orifices of both plain : foot very
large,
serrated at the sides.
Shell so closely resembling a dwarf or miniature form of
the last species, that it is only necessary to point out the dif-
ference. This never attains one -fourth of the cubical contents
of T. clonacina : it is more convex in every part and propor-
tionally more solid : the sculpture
is much finer and more
regular : the colouring is brighter and more varied, being rose,
pink, namecolour, orange, sulphur, lemon, or milk-white, frequently
of a uniform hue, but more often diversified by rays
as in the other species, besides having the longitudinal streak
on each side of the beaks ; specimens have occasionally trans-
