TERTIARY FAUNA OF FLORIDA 



list, 1864), from the Miocene of Oregon, seems to be a mere list name, as I 

 have been unable to find any other reference to it; T. (Peronidia) bodegensis 

 Hinds, 1844 (not the same as emacerata Conrad, 1849, as suspected by Gabb), 

 is abundant in the Pleistocene of San Diego and San Pedro, California; the 

 specimens cited under this name from lower horizons require further exam- 

 ination ; T. (Angulus) capillifera Conrad, 1866 (+ T. shilohensis Heilprin, 

 1887, list name), Lower Miocene of Shiloh, New Jersey; T. (Angulus) de- 

 clivis Conrad, 1834, Lower Miocene of Shiloh, New Jersey, of Plum Point 

 and Jones Wharf, Maryland, of Petersburg, Virginia, Upper Miocene of York 

 River and Suffolk, Virginia, Pliocene of Shell Creek, Florida, and Pleistocene 

 of North Creek, Osprey, Florida; this species is very close to T. (Angulus) 

 polita Say, of the recent fauna, but the latter is a more ventricose shell and 

 the right anterior lateral is longer than in the fossil ; T. (Peronidia?) egena 

 Conrad, 1834, Miocene of James River, Virginia; T. (Merisca) lintea Conrad, 

 1837 (not T. lintea Conrad, Vicksburgian, 1848, which is a Psammobia), 

 Upper Miocene or Pliocene of New Berne, North Carolina, a species very near 

 T. (nquistriata but larger and more produced ; T. (Angulus?) peracuta Conrad, 

 1866, a somewhat dubious species from the Lower Miocene marls of Cumber- 

 land County, New Jersey ; T. (Angulus) producta Conrad, 1840, Miocene of 

 Plum Point and Blake's Cliffs, Maryland, of Petersburg, Virginia, and the 

 Pliocene or transition beds at the northern end of the Dismal Swamp, Vir- 

 ginia. For other species refer to the genus Macoma and the following de- 

 scriptions. 



Tellina (Eurytellina) alternate, Say. 



Tcllina alternata Say, Journ. Acad. Nat. Sci. Phila., iv., p. 275, 1822 ; Tuomey and Holmes, 

 Pleioc. Fos. S. Car., p. 89, pi. 22, fig. 4, 1857; Conrad, Proc. Acad. Nat. Sci. Phila. 

 for 1862, p. 573, 1863 ; Gabb, Geol. St. Domingo, p. 248, 1873 ; Plioc. Fos. Costa 

 Rica, p. 371, 1881. , 



Pliocene of the Caloosahatchie beds, on Shell Creek and the Caloosahatchie 

 River, Florida; of South Carolina (Haldeman) ; of the Croatan beds and the 

 Neuse River below New Berne, North Carolina ; Pleistocene of Simmons 

 Bluff, South Carolina ; and recent from Cape Hatteras, North Carolina, south 

 to Belize and St. Domingo. 



I have not found any satisfactory evidence of the presence of this species 

 in beds earlier than the Pliocene, the references to the Miocene being due to 

 a confusion of Miocene and Pliocene deposits or misidentification with other 

 species. It is certain at least that the assertion that it is found in Miocene beds 

 requires confirmation. This species is said by Dunker and Krebs to be syn-
