THE MOLLUSCA OF DORSETSHIRE. 91 
SOLEN, Z. 
S. ensis, Z. 
Pulteney, p. 28, p. 4, f. 3. 
Inhabits deeper water than S. siligua, and is not, therefore, 
so frequently found thrown up on the shore. Common on 
the sandy parts of the coast. 
S. siliqua, J. 
Pulteney, p. 28, pl. 2, £. 5. 
A very common shell at Weymouth and between South 
Haven and Swanage. It buries itself under the sand 
to the depth of a foot or more, and on the incoming of 
the tide may be seen protruding its body a couple of 
inches or more, but suddenly recedes on the approach of 
footsteps. 
Fossil : Red Crag. 
S. vagina, L. S. marginatus, Pult. 
Pulteney, p. 28, pl. 4, f. 8. 
Differs from S. ensts in its straight valve, and from 
S. siliqua in having two teeth in each valve. 
Weymouth, dredged, Pulteney; common at low-tide, alive,

C. pellucidus (Pennant). Solen pellucidus, Penn. 
Forbes and Hanley, Vol. i., p. 252, pl. 13, f. 3.

immense range of depth from 6 to 100 fathoms. Inhabits 
sand, and sandy mud.
