Aleutian Is. to Catalina I. About San Pedro it 
can sometimes be found at very low tide. Note 
that the central scallop on the edge dips downward 
in this shell, while in the last species it bends up-

specimen for the cabinet.

ones are brown. Rich mark-

‘the foramen, or opening, is larger. It is found
