Heilprin, Angelo— Continued. 



the most nortberu locality in the State wbeie the members of tbo group of 

 Foramiuifera bave been found. IIo also received from approximately tbe 

 samelocalityArredonda, Alachua Couuty, specimens containing XtonmuHhs 

 floridanus, Orhitoidis, and Operculina rotella {0. complanata^). 

 Some marine Eocene fossils from tbe neigbborboodof Padncab, Kentucky, bave 

 also been leceivcd, and a list of tbe genera is given ; tbe borizon is con- 

 sidered to bo tbat of tbe older Tertiaries of Maryland and Virginia.

 and Zoology of tbe Floridan Peninsula. A ISTarrative of Researcbes

Tbe author concludes tbat tbero is not a particle of evidence sustaining tbe 

 coral theory of growtb of tbe peninsuhi. Tbe formations represented, in 

 tbo State are tbo Oligocene, Miocene, Pliocene, and Post-Plioceae, wbicb 

 follow each other in regular succession, beginning witb tbe oldest, from 

 tbe north to tbe soutb, tbus clearly indicating tbe direction of growth of 

 tbe peninsula. No indisputable Eocene rocks bave tbus far been identified 

 in tbe State, but not improbably some sucli exist in tbe more nortberly 

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

 ferred to tbe Oligocene. Fresb- water streams, and consequently, dryland, 

 existed in tbe more southern parts of tbe peninsula during tbe Pliocene 

 period, as is proved by tbe intcrassociation of marine and lliiviatile mol- 

 lusks in tbe deposits of tbo Caloosabatcbie. The modern fauna of tbe coast 

 is indisputably a derivative, through successive evolutionary changes of 

 tbe xjre-existing faunas of tbe Pliocene and Miocene periods of tbe same 

 region, auJ the immediate ancestors of many of tbe living forms, but 

 sligbtly diftering in specific cbaracters, can be determined among tbe Plio- 

 cene fo.ssils of tbe Caloosabatcbie. Tbe doctrine of evolution tbus receives 

 positive and most striking confirmation from tbe past invertebrate fauna 

 of tbe Floridan region. 



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

 improbably tbe fossilized remains found on Sarasota Bay, now wholly 

 converted into liinonite, represent tbe most ancient belongings of man tbat 

 bave ever been discovered.
