KINDERHOOK FORMA TIONS OF MISSO URI 1 4 I 



3. Ortholhetes inaequalis Hall? In the paper cited above, this shell 

 was identified as O. chemungensis. It is probably identical with one 

 of the species in the upper Kinderhook beds at Burlington, but may 

 not be the O. i?iaeqnalis. 



4. Schisophoria swallovi Hall. The specimens of this species resem- 

 ble those from the subjacent Sac limestone, and also those from the 

 superjacent Pierson limestone, but are usually larger than the Sac 

 limestone specimens. 



5. Rhipidomella burlingtonoisis Hall. The specimens of this species 

 are not unlike those from the other Kinderhook formations of the 

 region, but are usually larger than the Sac limestone specimens. 



6. Chonetes illinoisensis Worthen ? The specimens so identified should 

 perhaps rather be referred to C. multicosta Win., described from 

 the "yellow sandstone" at Burlington, Iowa. 



7. Productella concentrica Hall. A single individual of this species 

 resembles specimens of the same species from Burlington, Iowa. 



8. Spirifei' marionensis Shum. This is one of the most abundant 

 species in the fauna of the Louisiana limestone at its typical 

 exposures. It is also a common species in the oolite bed at Burling- 

 ton and occurs in the subjacent "yellow sandstone" at the same 

 place, as well as being more or less common in most of the upper 

 Kinderhook faunas. 



9. Spirifer striatiformis Meek ? This species is probably identical 

 with the one so identified from the Sac limestone. 



10. Syringothyris carteri Hall. Several specimens from Northview 

 have been referred to this species, although the characteristic 

 syrinx and punctate shell structure of the genus have not been 

 observed. 



11. Ambocoelia parva Weller. This species has only been observed in 

 this fauna and in the Eureka shale. 



12. Athyris lamellosa Lev. This species is a common one in the super- 

 jacent Pierson limestone, and is also a member of the typical 

 Chouteau limestone fauna. 



13. Cleiothyris sp. undet. These specimens are possibly identical with 

 those in the Sac limestone. 



14. Dielasma sp. undet. This shell is perhaps the same as that 

 described by Winchell as Centronella allei from the upper " yellow 

 sandstone" at Burlington. 



1 5. Crenipecten winchelli Meek ? This is a species which was originally 

 described from the Waverly sandstones of Ohio. 



16. Crenipecten laevis Weller. This species was described from North- 

 view, and is not known elsewhere.
