COAL MEASURE FAUNAL STUDIES, III. 

 LOWEE GOAL MEASUKES. 



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



T^HE authors are aware that the term "Coal Measures" is- 

 becoming obsolete, but, for the sake of uniformity, the 

 title will be continued in this and the succeeding papers. This 

 also is true of certain fossils given in the lists, such as the 

 Pleurotomarias and the Bellerophons. In the final paper the 

 terminology of the fossils will be carefully brought up to date. 



In collecting the material from the Lower Coal Measures the 

 authors, working together, endeavored to collect quantitively 

 the fossils found in the various horizons. The fact that one was 

 interested in the Bryozoa and the smaller Crustacea, while the 

 other was more familiar with the other forms, has, we hope, tended 

 to make the results more complete. Aside from this, every 

 effort was made to eliminate the personal equation so far as 

 possible. Particular care was taken not to overlook the com- 

 moner forms in order to secure the more rare ones. The latter 

 were, however, industriously sought, but every specimen seen 

 was noted and, whenever possible, was taken. However, these 

 lists are not to be looked upon as complete, for the faunas of 

 each horizon will be very materially increased by prolonged 

 and careful collecting. Our collections are sufficiently com- 

 plete, we believe, to show most of the salient features of the 

 faunas as units. The remaining additions will consist largely 

 of extending the known range of the forms in associated rocks* 

 and the discovery of rare and unique species. 



In the following lists the usual conventional characters in-

 without significance.
