 Miocene of Cumberland County, New Jersey? 

 Pliocene of the Caloosahatchie and Myakka Rivers, Florida ; Post 



Pliocene of the Atlantic and Gulf coasts from Prince Edward's Island to 



Florida, Texas, and California. Recent from Prince Edward's Island south 

 to Florida and west to Mexico, and on the west coast of Mexico near the 

 head of the Gulf of California. 



This well-known species occurs positively in the Pliocene of Florida, but 

 the Miocene citations require revision. Specimens from the New Jersey marls 

 received from Professor Whitfield under this name were either 0. georgiana 

 mut. uiaiiriccnsis or the young of 0. percrassa. Most of the southern species 

 thus named are better placed elsewhere. Say does not appear to have pub- 

 lished any Ostrea fiindata, though the name has been used on his authority 

 by Ravenel and Holmes. The long current-bred specimens, by confusion with 

 those which have become elongated by mutual compression, have received 

 the varietal name of procyon from Holmes. The same shell appears to be 

 the 0. rhirjophoriB of Guilding and Reeve, though not 0. rhirjopliora of 

 Dillwyn. 



The 0. lurida Cpr. (1863) and O. pahnula Cpr. (1857) with its variety 

 conchaphila Cpn. (t857) are laiown from the Post Pliocene of the Pacific coast. 

 I have not yet seen O.foliiun Linne or 0. cqncstris Say, in the fossil state, on 

 the east American coast. 



0. solea Conrad appears to be a mere list-name, never figured or de- 

 scribed. 0. Tuovieyi Coquand (Mon. Ostrea Terr. Cret., p. 68, 1869) was 

 proposed for the preoccupied name of crenulata Tuomey, but Conrad had 

 ah-eady used the specific name of Tuonieyi (1865) for a fossil oyster from 

 Mississippi, so if the Coquandian fossil is a good species it will require a new 

 name.
