 inch. 



Observations. — This species dif-

 being without tubercles and carina.

 present the appearance of a chain. Some of the old specimens are 

 quite black, while the younger ones are green or j'cllow. In some 

 cases where the apex is eroded or worn off and the shell black and 

 old, it looks like M. Virginica (Say), as no grains can be observed. —
