252 RECORD OP SCIENCE FOR 1886. 



Heilprin, Angelo— Continued. 



the most northern locality in the- State where the members of the group of 

 Foraminifera have been found. Ho also received from approximately the 

 same locality Arredonda, Alachua County, specimens containing iV^itmniunits 

 floridamis, Orhitoidis, and Opcrculina rotella {0. complanatal). 

 Gome marine Eocene fossils from the neighborhoodofPaducab, Kentucky, have 

 also been received, and a list of the genera is given ; the horizon is con- 

 sidered to be that of the older Tertiaries of Maryland and Virginia. 



Heilprin, Angelo. Explorations on tbe West Coast of Florida and 

 in the Okeechobee Wilderness, with Special Reference to the Geology 

 and Zoology of the Floridan Peninsula. A Narrative of Researches 

 undertaken under the Auspices of the Wagner Free Institute of 

 Science of Philadeli)hia. (Trans. Wagner Free Institute Sci., vol.

The author concludes that there is not a particle of evidence sustaining the 

 coral theory of growth of the pcninsuhi. The fornuxtious represented in 

 the State are the Oligoceue, Mioceuc, Pliocene, and Post-Pliocene, which 

 follow each other in regular succession, beginning with the oldest, from 

 the north to the south, thus clearly indicating the direction of growth of 

 the peninsula. No indisputable Eocene rocks have thus far been identified 

 in the State, but not improbably some such exist in the more northerly 

 sections, and possibly include even a part of what has generally been re- 

 ferred to the Oligocene. Fresh- water streams, and consequently, dryland, 

 existed iu the more southern parts of the peninsula during the Pliocene 

 period, as is proved by the interassociation of marine and fluviatile mol- 

 lusks in the deposits of the Caloosahatchic. The modern fauna of the coast 

 is indisputably a derivative, through successive evolutionary changes of 

 the pre-existing faunas of the Pliocene and Miocene periods of the same 

 region, and the immediate ancestors of many of the living forms, but 

 slightly differing in specific characters, can be determined among the Plio- 

 cene fossils of the Caloosahatchic. The doctrine of ev^olution thus receives 

 positive and most striking confirmation from the past invertebrate fauua 

 of the Floridan region. 

 Man's great antiquity on the peninsula is established beyond a doubt, and not 

 improbably the fossilized remains found on Sarasota Bay, now wholly 

 converted into limonite, represent the most ancient belongings of man that 

 have ever been discovered.
