BIVALVIA. 233 
smooth ; right valve covered with oblique striz ; hinge with two cardinal teeth, and 
small lateral tooth. 
Length, 2 inch. Height, ¢ inch. 
Locality. Mam. Crag, Southwold. Recent, British Seas, Mediterranean. 
One specimen was found by Captain Alexander some years since, but it is now 
unfortunately lost. I am, however, certain of its existence as a Crag shell, and have 
in consequence given the representation of a recent individual. 
Philippi gives it as a living species in the Mediterranean, but not as a fossil from 
that part of the world. He places it in his section of the genus “ dentibus lateralibus 
carentes.” It is not, however, strictly speaking, destitute of lateral teeth; there is a 
distinct and proximate one on the anterior side of the right valve, and another smaller, 
but more remote, on the posterior margin, immediately beyond the ligamental fulcrum. 
The right valve is prettily ornamented with numerous oblique strize, placed close and 
straight on the siphonal side, and are rather more distant and wavy on the anterior 
half. 
This I have found in the recent state on the sandy shores of the Eastern Coast of 
England, and almost within the reach of fresh water. Itis usually a littoral species, and 
is said to range to the depth of ten or twelve fathoms.
