5 TERTIARY FAUNA OF FLORIDA 



Corbula ffi-ruginosa Greene, Mass. Cat., 1833 ; not of Wood. 



Azara contracta H. and A. Ads., Gen. Rec. Moll., ii., p. 357, 1856. 



Corbula cuneata Tuomey and Holmes, Pleioc. Fos. S. Car., p. 75, pi. 20, fig. n, 1855 ; 



not of Say or Conrad. 



Corbula contracta Holmes, P.-Pleioc. Fos. S. Car., p. 56, pi. 8, fig. 17, 1858 ; Dall, Bull. 

 U. S. Nat. Mus., No. 37, p. 70, pi. i, fig. 6 a-b, pi. 59, fig. 10, 1889. 



Pliocene of the Croatan beds, North Carolina, and of the Caloosahatchic 

 marls in south Florida; Pleistocene of Heislerville, New Jersey, and Sim- 

 mons Bluff, South Carolina, and Sankoty Head, Massachusetts. 



Recent from Cape Cod, Massachusetts, to Jamaica. 



This species has been reported from the Oligocene of St. Domingo and 

 the Pliocene of Costa Rica by Gabb, but it is probable that some of the allied 

 species were confounded with it. I have seen no specimens from beds older 

 than the Pliocene. 



Corbula (Cuneocorbula) Barrattiana C. Ii. Adams. 



Corbula Barrattiana Adams, Contr. Conch., xii., p. 237, 1852 ; Dall, Bull. U. S. Nat. 

 Mus., No. 37, p. 70, pi. 2, fig. 7 a-c, 1889. 



Pliocene of the Waccamaw beds at Tilly's Lake, South Carolina, and 

 in the marls of the Caloosahatchie and Shell Creek, Florida ; Dall and 

 Willcox. 



This shell resembles somewhat C. engonata Conrad, but has finer, closer, 

 and more even sculpture, and a strongly marked rostral area, on which, when 

 perfect, fine radial lines can be made out which do not occur on the disk of 

 the shell. 



Corbula (Cuneocorbula) Dietziana C. B. Adams. 



Corbula Dietziana Adams, Contr. Conch., xii., p. 235, 1852 ; Dall, Bull. U.S. Nat. Mus., 

 No. 37, p. 70, pi. i, fig. 5 a-b, 1889. 



Pliocene clays of Port Limon, Costa Rica; Mill. 



Recent, from Cape Hatteras, North Carolina, to Barbados. 



This strongly marked species is rare in the fossil state, but not uncommon 

 in the recent fauna. 



Corbula diegoana Conr. (P. R. R. Rep., v., p. 322, pi. 3, fig. 16, 1855) 

 and Corbula luteola Cpr. (1863) have been reported from the Pleistocene of the 

 Pacific coast; C. carinifera Gabb (Geol. St. Dom., p. 258, 1873) from that of 

 St. Domingo.
