This species may be separated from A. incerta, Smith, 

 both by its form and 'sculpture. Tliat species is narro\v 

 anteriorly and widens behind, whereas the present form is 

 almost equally broad at both ends. Tlie surface of the 

 valves is less distinctly granulated and the ribs upon the 

 posterior slope are fewer, broader, and further apart than in 

 incerta. Tbe hinge-teeth are different in the two species, 

 those at the hinder end of incerta\hem^ peculiarly oblique, 

 whereas in this species they are more^upright and coarser.
