TERTIARY FAUNA OF FLORIDA 



Eocene at Claiborne Bluff and Wood's Bluff, and the Jacksonian of Choctaw 

 County, Alabama, are well-established species. Lticina estrellana and L. tetrica 

 Conrad, 1857, are unidentifiable Californian fossils of unknown horizon. 



Only two species of the typical section remain to be particularly mentioned. 



Phacoides domingensis n. sp. 



PLATE 50, FIGURE ir. 



Oligocene of the Bowden horizon on the island in Lake Henriquillo, St. 

 Domingo ; at Bowden, Jamaica, and Ballast Point, Tampa Bay, Florida. 



Shell closely resembling P. pectinatus (for which it has been taken by 

 Guppy), but smaller, more inflated, with the notch in front of the anterior 

 dorsal area more indented and angular, the concentric lamellation more distant 

 and more evenly spaced, and the posterior dorsal area shorter in proportion and 

 more triangular. Alt. 31, Ion. 34, diam. 19 mm. 



'This is with little doubt the Oligocene precursor of P. pectinatus, and was 

 regarded as identical with it by Gabb and Guppy.

Pliocene of the Caloosahatchie, Shell Creek, Alligator Creek, and the 

 Myakka River, south Florida; Pleistocene of south Florida and the Antilles, 

 and of the north coast of South America ; recent from St. Augustine, Florida, 

 southward, throughout the Antillean region and along the east coast of South 

 America as far as Montevideo, Uruguay. 



This species, which is better known by the later name of jamaicensis applied 

 by Spengler after the non-binomial Chemnitz, was reported in 1841 by Conrad
