Conrad considered this species identical with his Oniscia 

 harpula from the Vicksburg Oligocene; but. Gabb pronounced the 

 Santo Domingo species "very different." We have no specimen 

 of the Vicksburg shell, but the description and figure are remark- 

 ably like the Dominician shells. The fossil series is M. harpula, 

 chipolanum and domingense. The living representative is M. 

 Dennisoni Reeve, of the Lesser Antilles. M. domingense is one 

 of the few species common to the Tampa silex beds and the 

 Santo Domingo blue clays.
