14 CARBONIFEROUS AMMONOIDS OF AMERICA. 



The Kinderhook stage of Iowa has furnished Prodromites gorhyi 

 Miller, Agoniatites opimus White and Whitfield. 



Cephalopod faunas of the Tournaisian formation, the European equiv- 

 alent of the Kinderhook, are known at Tournai in Belgium, Erdbach in 

 Germany, and in Ireland, where the most characteristic genera are Jgauides, 

 Frolecanites, Pericyclus, and Muensteroceras, some of the species probably 

 being: identical with American forms. 



Cephalopod faunas of Tournaisian age are not yet known elsewhere 

 in the world. ' 



Osage. — While marine deposits of Osage or Burlington-Keokuk age 

 are widelv distril^uted in America, ammonoids are cited from but two 

 places — from the Burlington limestone of Louisiana, Mo. {Muenstero- 

 ceras f osagense Swallow), and from the Upper Waverly formation of Ohio 

 (Aganidesf sciotoensis Miller and Faber). 



St. Louis- Chester. —The St. Louis-Chester, or Ste. Grenevieve, stage 

 of Indiana and Kentucky has furnished the following species: Glgphio- 

 ceras Icvicuhun Miller and Faber, Goniolohocerasf limatuin Miller and Faber, 

 Goniatltes kentuckiensls Miller, G. greencastlensis Miller and Ourley, G. 

 subcircularis Miller, 



The only goniatite found in lUinois in this formation is Nomismocerasf 

 monroense Worthen. 



The lower part of the St. Louis-Chester stage in Arkansas, the 

 so-called Fayetteville shale, has yielded Bactrites carhonarius Smith, 

 Ghjpliioceras calyx Phillips, Goniatites crenistria Phillips, G. neivsomi Smith, 

 G. sphcericus Martin, G. striatus Sowerby, G. subcircularis Miller. The 

 upper part of the St. Louis-Chester in Arkansas, the Boston group, has 

 yielded Fronorites cyclolobus Phillips, var. arkansasensis Smith, and Gastrio- 

 ceras hranneri Smith. 



The Bend formation of Texas, wdiich has been assigned by the writer 

 to the St. Louis-Chester, has yielded Goniatites crenistria Phillips, G. striatus 

 Sowerby, Gastrioceras compressmn Hyatt, G. entogonum Gabb, Paralegoccras 

 iowense Meek and Worthen, and P. texanum Shumard. 



Cephalopod faunas of St. Louis-Chester age are known in the Vis^ 

 formation of Europe at Visd in Belgium, at BoUand in Yorkshire; in the 

 Culm of the Hartz Mountains; in the upper Kohlenkalk of Silesia; and 

 in the Carboniferous limestone of the Pyrenees in Spain. The most char-
