32. Bellerophon vinculatus W. & W. This species is much more 



common at English River than at Burlington. 

 i ) 7 ) . Bellerophon sp. undet. Two undetermined species of this 



genus are recognized in this fauna, one or both of which are 



probably undescribed. 



34. Euphemus sp. undet. Two species of this genus occur in the 

 English River fauna, both of which are probably undescribed. 

 The genus has not been observed in the Chonopectus fauna at 

 Burlington, and heretofore it has been described from the 

 Kinderhook only in the faunas of central and southwestern 

 Missouri. 



35. Porcellia obliquinoda White. A single fragment of a shell of 

 this species has been observed from English River, but, so far 

 as it is preserved, it is essentially similar to specimens from the 

 Chonopectus fauna at Burlington. 



36. Dentalium grandaevum Win. This species, which is present 

 in the Chonopectus fauna at Burlington, and also in the fauna 

 of the upper yellow sandstone (bed No. 5) at the same locality, 

 is represented by numerous fragments in the English River 

 fauna. 



37. Orthoceras whitei Win. A single imperfect fragment of this 

 species has been observed, but it is sufficiently well preserved to 

 make its identification certain. 



38. Orthoceras heterocinctum Win. This species is somewhat more 

 common than the last, but it is always preserved in a fragmentary 

 condition. 



39. Phragmoceras expansum Win. ? A fragmentary specimen is 

 identified with a query as this species, but too little of the speci- 

 men is preserved to make the identification certain. 



40. Fish remains ? Eastman 1 has called attention to some small, 

 peculiar, bilobed bodies from Burlington, where they occur in the 

 Chonopectus Sandstone, which are probably icthic in nature, but 

 their systematic position cannot even be guessed. Similar speci- 

 mens occur in the English River Grit, although they seem to be 

 specifically distinct from the Burlington specimens. Occurring 

 as they do in this fauna at distant localities, it becomes a matter
