TERTIARY FAUNA OF FLORIDA 



Venus cingenda Dillwyn, Cat. Rec. Shells, i., p. 161, 1817; Wood, Index Test., pi. vii., 



fig. 6, 1828. 

 Venus dysera Auctorum, non Linne. 



Venus elevata Say, Journ. Acad. Nat. Sci. Phila., ii., p. 272, 1822. 

 Venus lamellata Deshayes, Cat. Conch. Brit. Mus., p. 134, i8s3> in synonymy; not of 



Linne. 

 Chione cancellata Deshayes, op. cit., p. 134, 1853. 

 Dione (Chamelea) cancellata Meek, Checkl. Miocene Fos. N. Am., p. 10, 1864. 



?Miocene of the Galveston artesian well, Harris, and of the Sumter dis- 

 trict, South Carolina, Tuomey and Holmes ; Pliocene of the Caloosahatchie 

 beds of the Caloosahatchie River, Alligator Creek, and Shell Creek ; Pleisto- 

 cene of Osprey, Florida, at North Creek, and in Quaternary beds generally 

 throughout the State; also at Simmons Bluff, South Carolina; recent from 

 Cape Fear, North Carolina, to the West Indies. 



It is possible that this species does not appear in the Miocene, and that 

 Holmes' South Carolina specimens, . some of which are before me, are really 

 Pliocene. They have that aspect and no specimens from undoubted Miocene 

 strata are in the National Collection. 



Chione niississippiensis Conrad, from the Vicksburgian, appears to be rare. 

 Among many collections made at the typical locality none has been found. 

 Chione simillima Sowerby and C. succincta Valenciennes are not uncommon 

 in the Pleistocene of San Diego, California, and still live on the adjacent coast. 



(Group of Chione subrostrata.) 



Chione Walli Guppy. 

 Venus Walli Guppy, Quart. Journ. Geol. Soc. Lend, (v.), xxii., p. 580, pi. xxvi., fig. 16, 

 1866. 



Eocene of Manzanilla, Trinidad, Guppy ; Oligocene of Bowden, Jamaica, 

 Vendryes. 



This species has the aspect of being the precursor of C. subrostrata, C. 

 amathusia, and similar forms of the recent fauna. 



(Group of Chione pubera.) 



Chione 'Woodwardi Guppy. 

 Venus Woodwardi Guppy, Quart. Journ. Geol. Soc. London (v.), xxii., p. 292, pi. xviii.,
