20. Schizodus depressus? 



This species was originalh- described from the oolite bed of 

 the St. Louis group in Monroe county, 111. 



21. Schizodus?? sp. 



This species affords no evidence bearing on the age of the 

 fauna in which it occurs. 



22. Sanguinolites ? sp. 



Like the preceding, this apecies affords no evidence in the 

 problem. 



23. Capulus acutirostris. 



This species, originally described from the St. Louis group, 

 also occurs in the Osage group below. The bearing of its evi- 

 dence is towards the St. Louis age of the fauna. 



24. Bellerophon sublsevis. 



This species is typically from the St. Louis group, where it is 

 a characteristic form. 



25. Bellerophon hranneri. 



This new species is not similar to any heretofore described 

 Carboniferous species and affords no evidence in the case. 



26. Straparollus similis? 



This species was originall}- described from the St. Louis group. 

 27. Straparollus sp. 



This fragmentary species affords no evidence in the present 

 problem. 



28. Orthoceras eurekensis? 



This species was described from Nevada, and its presence in 

 the Batesville Sandstone fauna can liave no bearing upon the age 

 of the formation. 



29. Glyphioceras spyhsericus. 



This species has not heretofore been recorded from America. 

 The nearest American ally is G. kentuckiensis from the St. 

 Louis group in Kentuckj*. 



30. Phillip)sia sp. 



The members of this genus range from the Kinderhook group 

 to the Coal Measures, and the presence of an indeterminable 

 species in the fauna affords no evidence as to its age.
