Division II. — Shell ovate or ohlong. 



The shells of this division present but little beauty, 

 with the exception of the S. oriens, S.radiatus, S. ro- 

 seus, and a few others, which have a fine pink color, or 

 are delicately rayed with purple and white. Some 

 species of this division closely resemble the Tellinae, 

 but they may always be distinguished by an exami- 

 nation of the hinofe.
