TERTIARY FAUNA OF FLORIDA 



The fine Periploma argentaria Conrad, 1837, is not infrequent in the Pleis- 

 tocene marl of San Diego, California.

Our investigations have not resulted in the rediscovery of this species, which 

 recalls on a larger scale the typical Cochlodesma Leanum (Conrad) Couthouy 

 of the recent fauna. The latter has not yet been reported in the fossil state.

The genus Laternula Bolten contained two species, Mya truncata and Solen 

 anatinus of Linne. Since the former is a member of the prior genus Mya 

 Linne, as restricted by Retzius, 1788, and Spengler, 1793, only one remains 

 to carry the name and typify it. Anatina Larrfarck was founded on the same 

 type ten years later, though a mass of heterogeneous species were assembled 

 under it by Lamarck himself arid subsequent writers, and it was a quarter of 

 a century before the confusion was rectified. 



The genus Laternula, or Anatina, is Oriental in its recent distribution, and 

 is not known from the North American Tertiaries. Several species belonging 

 to other groups, as now understood, were originally described as Anatina, and 

 are occasionally cited in later literature under this name. Thus Anatina clai-
