14 THE DEVONIAN OF MISSOURI. 



(Linnnaeus) have been identified in other formations. The fauna 

 has a Middle Devonian aspect but does not agree with any 

 other Middle Devonian fauna. Its relationship to the Mineola 

 places it in the very earliest Middle Devonian. It is probable 

 that more extensive collecting will add many species to those 

 known from the formation. 



The following list contains all of the identifiable forms that 

 the writer has collected from the Cooper limestone: 



Coelenterata 



Favosites alpenensis Winchell 

 Streptclasma cooperensis Branson 



Brachiopoda 



Atrypa reticularis (Linnaeus) 

 Gypidula marionensis Greger 



Pelecypoda 



Lunulicardium grande Miller and Gurley 



Gastropoda 



Pleurotomaria providencis Broadhead 



In addition to the list there are two or three species of 

 gastropods, two cephalopods, two or three bryozoans, and three or 

 four brachiopods that are too fragmentary for description. 



Greger 1 li ts the following species, all but two undescribed, 

 of which the writer has seen only fragmentary materials. 



Bryozoa, 2 species, gen. et sp. indet. 

 Stromatopora sp. 

 Favosites sp.

 Spirifer lupusensis sp. nov. 

 Schuchertella altirhynchus sp. nov.
