17. Pcmopecten cooperensis Shum. This is one of the commonest 

 species in the Northview sandstone, and is also one of the most 

 characteristic species of beds 5 and 6 of the Burlington section. It 

 was originally described from the Chouteau limestone of Cooper 

 county, Missouri, and is a common shell in some beds of the Chou- 

 teau limestone. 



18. Modimorpha northview ensis Weller. This species has only been 

 recognized at Northview. 



19. Macroden sp. undet. This species has not been identified, but the 

 genus is represented in the upper "yellow sandstone" fauna at 

 Burlington by a very common species. The genus is also repre- 

 sented in the typical Chouteau limestone. 



20. Cardiopis radiata M. and W. This species originally described 

 from the goniatite limestone at Rockford, Indiana, also occurs in 

 the Chouteau limestone in Pettis county, Missouri. 



21. Cardiopsis erectus W eller . This species was first described from 

 Northview, and has not been recognized elsewhere. 



22. Palaeoneilo sp. undet. This species was formerly identified with a 

 query as P. constricta Con., but it is probably distinct. It is closely 

 allied to P. microdonta Win. of the upper "yellow sandstone" at 

 Burlington, but is usually larger. 



23. Palaeoneilo truncata H. This species, originally described from the 

 Waverly sandstones of Ohio, is represented in the upper " yellow 

 sandstone" at Burlington by P. barrisi W. & W. a similar but 

 smaller species. The genus Palaeoneilo does not occur in the 

 Chonopectus fauna at Burlington, and has not been recognized in 

 any of the lower Kinderhook faunas. 



24. Schizodtcs aequalis Hall. This is a Waverly sandstone species, and 

 has not been recognized elsewhere in the Kinderhook. 



25. Elymella missouriensis M. & G. This species was originally 

 described from the Chouteau limestone of Pettis county, Missouri. 



26. Promacrus websterensis Weller. This was described as a new 

 species from Northview. 



27. Promacrus cimeatus Hall. In the description of the fauna of the 

 Chonopectus sandstone, 1 this species was provisionally included. 

 Since that time, however, through + .he courtesy of Dr. E. O. Hovey, 

 of the American Museum of Natural History, the type specimen of 

 P. cuneatus has been examined by the writer, and it proves to have 

 come from the upper "yellow sandstone," bed No. 5, at Burlington. 

 The genus Promacrus is represented by several species in the
