NORTHERN AND SOUTHERN KINDERHOOK FA UNAS 627 



3. Schizophoria cf. S. swallovi Hall. This species is represented 

 in the collection by a single specimen. It is specifically iden- 

 tical with the species in the Chonopectus Sandstone at Burling- 

 ton, which has been referred to S. swallovi. The condition of 

 preservation of neither the Burlington nor the English River 

 specimens is sufficiently good to make such an identification 

 absolutely certain, but they seem to agree more closely with that 

 Burlington Limestone species than with any other. 



4. Chonopectus fischeri (N. & P.). This species, which is so 

 characteristic of the fauna at Burlington, is present in the English 

 River Grits, but is much less common. 



5. Productus laevicostus White. This Productus is one of the 

 less common species of the fauna, but it differs in no essential 

 respect from specimens occurring elsewhere. 



6. Productus curtirostris Win. 



7. Productus 2 or 3 undet. species. 



8. Productella concentrica Hall. Several specimens of this species 

 are present in the collection from English River, which are 

 indistinguishable from examples occurring in the faunas of 

 beds Nos. 5 and 6 at Burlington, but the species has not been 

 observed at the latter locality in the Chonopectus Sandstone. 



9. Productella nummularis (Win.). This is one of the common 

 species in the English River fauna, while at Burlington it is rare. 

 Individuals from the two localities agree closely in all essential 

 respects. 



10. Paraphorhynchus transversum Weller. This is a rare species 

 in the English River fauna, but the specimens differ in no essen- 

 tial characters from those occurring at Burlington and Kinder- 

 hook. 



11. Rhynchonella ? sp. A single specimen too imperfectly pre- 

 served for recognition. 



12. Eumetria altirostris White. In the English River fauna this 

 species grows to a larger size and is much more abundant than 

 in the Chonopectus Sandstone at Burlington. 



13. Athyris corpulenta (Win.). This species is much more common 

 in the English River fauna than at Burlington, but none of the 

 specimens observed are perfectly enough preserved to admit of
