This interesting species, named after its resemblance 
to the human ear, is found in rivers, lakes, ponds, and 
canals in many parts of the country. It is common 
and fine in the Thames, in canals in Lancashire, and 
other places. A soft tooth-brush may be used with 
great advantage to remove the dirt and confervoid 
which become very firmly attached to the shell.
