TERTIARY FAUNA OF FLORIDA 



The Liicina subobliqiia Say ( Journ. Acad. Nat. Sci. Phila., iv., p. 147, 1824) 

 is still unfigured and I have not seen specimens. It would appear to be a Miltha 

 from the description, though only four-fifths of an inch in length, and was ob- 

 tained from the Miocene of Maryland, probably in St. Mary's County. 



Phacoides (Pseudomiltha) anodonta Say. 

 Lucina anodonta Say, Journ, Acad. Nat. Sci. Phila., iv., p. 146, pi. x., fig. 9, 1824; Conrad, 



Fos. Medial Tert., p. 40, pi. xx., fig. 4, 1840; Tuomey and Holmes, Pleioc. Fos. S. 



Car., p. 55, pi. xviii., fig. 2, 1857; Emmons, Geol. N. Car., p. 291, 1858. 



Miocene of Maryland near Easton and on the Patuxent River, the St. 

 Mary's River, the Choptank at Barker's Landing, Blake's Cliffs, Skipton, Jones 

 Wharf, Plum Point, Calvert Cliffs, and in St. George County ; of Virginia at 

 City Point and Grove Wharf on the James River, Urbana, Petersburg, and 

 the York River; of North Carolina at Wilmington; Pliocene of the Wac- 

 camaw district. South Carolina, and of the Caloosahatchie, Shell Creek, and 

 Alligator Creek, Florida. 



This widely distributed species, notwithstanding a certain amount of varia- 

 bility, is easily identified and its heavy shell, more or less irregularly externally 

 wrinkled, and obsolete hinge-teeth are conspicuous characters. 



The Lttcina undula Conrad (Fos. Medial Tert., p. 71, pi. xli., fig. i, 1845) 

 from its effaced hinge would appear to belong in this vicinity, and the type may 

 have been an abnormal P. anodonta. It came from Craven County, North 

 Carolina, on the Neuse River, and the figure looks not unlike some specimens 

 of P. Foremani. 



Phacoides (Pseudomiltha) Foremani Conrad. 

 Lucina Foremani Conrad, Journ. Acad. Nat. Sci. Phila., viii., p. 184, 1842; Proc. Acad.

Geol. Rep. N. Car., p. 291, fig. 217, 1858; Conrad, Proc. Acad. Nat. Sci. Phila. for 



1862, p. 577, 1863. 



Miocene of Maryland at Calvert Cliffs, Blake Cliffs, and Plum Point ; Burns 

 and Harris. 



A rude, rather convex and rotund species, distinguished from P. anodonta 

 by its smaller size, more convex and rounded shell, and usually by its sharper 

 concentric sculpture. 



Phacoides (Pseudomiltha) floridanus Conrad.
