Coal Measures Faiinal Studies. 1. 



BY J. W. BEEDE AND AUSTIN F. ROGERS. 



It is proposed by the authors, in a series of papers with the 

 above title, to give lists of the faunas of the different horizons of 

 the Coal Measures of Kansas and certain parts of western Mis- 

 souri. The several papers will be written by the authors separately 

 and each alone is responsible for the information contained therein. 

 In the final paper, the joint production of the two authors, some 

 generalizations as to the distribution of species in the Coal Meas- 

 ures will be attempted. 



Several things have led to the production of this series. The 

 faunal relations of the Upper and Lower Coal Measures is chief 

 among them. At present there seems to be no sharp faunal break 

 between them and no unconformity of strata, making a very careful, 

 study of the fossils of the entire range necessary. It will also serve 

 as a check list, and, it is hoped, bring out fossils as yet unknown 

 to the region which may throw additional light on the subject. In 

 the third place it will assist greatly in determining the relationships 

 between the faunas of the Permian and the Coal Measures. Care- 

 ful collecting such as is necessary in a work of this kind brings to 

 light fossils which would otherwise escape notice. This is partic- 

 ularly true of the range of the more inconspicuous species. 



The lists are, of course, somewhat incomplete, yet it is believed 

 that they represent the typical faunas of the several horizons at the 

 localities mentioned. 



The fossils herein listed are those collected by the authors or 

 studied by them in the collections made by careful collectors, in 

 which the specimens were carefully and accurately labelled. 



The next number of the series will be on the fauna of the 

 Shawnee, Wabaunsee, and Cottonwood formations, the remaining 

 formations of the Coal Measures beneath the Permian, by Mr. 

 Beede.
