Tellina (Arcopagia) fausta. Donovan, Vol. III., p. 98. 

 Semele variegata. 



I find a shell in the Mtis. Phil. Acacl. marked by this name, from the Coast of 

 Brazil, identical with one of my fossil species, but have failed to find it in the books.

Ostrea V i r g i n i c a. Gmel. 



The typical long variety, showing a few radiations on the beaks occasionally, 

 occurs not only at Macoris, but also at one or two localities in the province of Seybo 

 along the ancient Post Pliocene shore-line. Beds of a small thin-shelled oyster, 

 probably a local variety, occur on the Bani coast road, just west of the jSi^igua River, 

 where the coast gravels merge into the old border reef of calcareous matter. The 

 oyster-bed was evidently on the shore flank of the reef.

 O. folium. Gmel., Syst. Nat. 



This species, like the other two, is still abundant on the coast. I believe it to be 

 identical with O.frons.
