564 TRANS. OP THE ACAD. OF SCIENCE. 



Morton's Farm, near Nebraska City, at Rock Bluffs and Plattesmouth, 

 have been determined by my friend, Prof. H. B. Geinitz, of Dresden 

 (Saxony), who has described the new species in a large memoir, with fine 

 plates, in the Acts of the Leopoldine Academy of Natural Sciences (Leo- 

 poldinisch-Carolinische Akad. (kr Naturforscher) , under the title of the " Car- 

 boniferous Formation and the Dyas in Nebraska." 



A great number of the fossils of Nebraska City are identical with spe- 

 cies found in Europe in the Zechstein or Magnesian Limestone, as Serpula 

 planorbites, Schizodus Rossicus, Allorlsma elegans, Solemya biarmica, Nucula 

 Kazanensis, Clidophorus Pallasst, Stenopora columnaris, etc., etc. The new 

 species are allied, or very near, to Dyassic species of Saxony, Russia, and 

 England. Finally, there are some Carboniferous species, which, in Ne- 

 braska as in Europe, pass into the Dyas. Naturally the more we descend 

 in the series of the Dyassic rocks, and approach the strata which are in 

 contact directly above the Carboniferous rocks, the fossils of the Carbonif- 

 erous epoch become more numerous and more nearly the same in certain 

 places ; as in the section at Plattesmouth they prevail over the Dyassic 

 forms. The Brachiopods, especially, are the fossils which pass in this 

 manner from the Carboniferous into the lower Dyas.
