The fossils of the Kinderhook beds at Burlington at one 

 time attracted much attention from paleontologists and local 

 collectors, but of late years they have usually been neglected. 

 The first species described from any of the beds was Gyro- 

 ceras burlingtonensis, described by Owen * in 1852 from the 

 oolite bed No. 6 (Weller). A little later (1858), in his pale- 

 ontology of Iowa, Hall f described and illustrated a number 

 of species of brachiopods and a few pelecypods from the 

 ** yellow sandstone " at Burlington. 



The most important collection of Kinderhook fossils from 

 Burlington that has been brought together was made by Dr. 

 C. A. White when he was a resident of that city. The 

 '* White collection," which is now the property of the Uni- 

 versity of Michigan, formed the basis for several important 

 papers, devoted to the description of Burlington fossils, by 

 C. A. White,t by C. A. White and R. P. Whitfield,§ and by 

 A. Winchell. || In these papers many species were described 

 but without illustrations, so that their identification by other 

 observers and from other localities has always been exceed- 

 ingly difficult or impossible. Many of these species have re- 

 mained without illustrations up till the present time, a large 

 number of those recorded in the present paper being now 

 figured for the first time. 



During the preparation of the descriptions of New York 

 Devonian pelecypods for the Paleontology of New York, Hall If 

 described and illustrated several of the Burlington ** Yellow 

 Sandstone *' species that were related to New York Devonian 

 species, the figures in most cases being drawn from the type 

 specimens. More recently Keyes** has published upon some 

 of the gasteropods from the Kinderhook beds at Burlington, 

 but his identifications of the species were apparently not based
