NOTICES AND DESCRIPTIONS OF FOSSILS, FROM THE MAR- 

 SHALL GR0UP1I2 OF THE WESTERN STATES, WITH NOTES 

 ON FOSSILS FROM OTHER FORMATIONS. 



By Alesandek Winchell, Director of the Geological, Survey op 



Michigan. 



The following notices and descriptions were drawn up in March last, 

 bnt their publication has been delayed by pressing and unremitting en- 

 gagements, which continued, very unexx^ectedly, through the entire 

 Summer. 



These studies are based chiefly on specimens fx'om Tennessee and Ohio. 

 The Tennessee specimens were submitted (with others) by Prof. James 

 M. Safford, about three years ago, and the conclusions have very recently 

 been announced in his Report on the Geology of that State. The Ohio 

 specimens consist of fossils communicated from time to time, during two 

 or three years past, by Rev. Herman Herzer, and of a series of fossils col- 

 lected by Prof. E. Andrews, along a section extending from the Blue 

 Limestone, near Cincinnati, along the Ohio river to the Coal Measures, '"^ 

 and others collected in Central Ohio and western Pennsylvania. 



In order that the references-in the following pages may. be made intel- 

 ligible, I subjoin the section communicated by Prof. Andrews:
