KINDERHOOK FAUNAL STUDIES. III. THE FAU- 

 NAS OF BEDS NO. 3 TO NO. 7 AT BURLINGTON, 

 IOWA.* 



Stuart Weller. 

 Introduction. 



In the second paper of this series of Kinderhook Faunal 

 Studies! the fauna of the Chonopectus sandstone, or bed No. 

 2 in the Burlington section, was described. The present 

 paper contains descriptions of the faunas of all the beds in 

 the same section lying above the Chonopectus sandstone and 

 below the Burlington limestone. These two papers, therefore, 

 will cover the entire series of Kinderhook faunas at Burling- 

 ton, which were long ago investigated by White, J White and 

 Whitfield, § and Winchell, H and most of the species described 

 by these men are here illustrated from the type specimens pre- 

 served in the University of Michigan collection. There still 

 remains to be described a single member of the series of 

 fossil faunas at Burlington, that of bed No. 1, a fauna that 

 was unknown to the earlier investigators. 



In these studies it is not presumed that the fauna of any 

 one of these beds has been exhaustively investigated. 

 Future collections will certainly bring to light additional 

 species in each of the faunas which have been described, but 

 each fauna has been here treated as fully as the material at 

 hand, from several different sources, would admit, and it is 

 believed that enough has been presented to materially assist in 

 the correlation of the faunas with those from other localities.
