TERTIARY FAUNA OF FLORIDA ^ 



The P. scrrata was founded upon a. very finely spinulose young shell, 

 which is, however, quite recognizable. The P. squaiiiosissiiiia was described 

 from adult Texan specimens. It is the Pinna scminnda of most American 

 authors, following Reeve, but not of Lamarck, 



The only other fossil PinncB which I find recorded from the American 

 Tertiaries are P. {Atrind) alamedensis Yates, from the Miocene of Alameda 

 Creek, Alameda County, California, and P. {Atrina) venturensis Yates, from 

 the Pliocene of Casitas Pass, Ventura County, California. These are figured 

 and described in Bull. No. 4, Cala. State Mining Bureau, San Francisco, 1894, 

 p. 56, pi. iv., figures 53 and 54. The two figures do not afford any evident 

 distinction between the two species. A Pinna alentica, described from Alaska 

 by Eichwald (Geogn. Pal. Bemerk, p. 183, pi. xv., fig. 11, 1871), appears to be 

 of Mesozoic age. 



Aldrich notes the presence of a very large Pinna {scnso latd) in Monroe 

 County, Coffeevi'Ile, Alabama, in the lower bed of the Wood's Bluff group, 

 and also at Nanafalia. Vaughan found a species, possibly referable to A. 

 argcntea, in the Jacksonian, at Creole Bluff, Louisiana.
