Report of the State Geologist. 193 



marize the succession of the faunas in this section in such a manner 

 as has probably never before been possible in an equal thickness 

 of the Palaeozoic rocks. These data have been brought together 

 on the basis of the geological section prepared by Mr. Luther, 

 vrhich will be communicated with the final report on these 

 investigations. The value of such a communication would 

 be enhanced by the description and illustration of such 

 new or little knoAvn species as have been obtained from the 

 shaft. Unfortunately, however, there is at present no portion 

 of the Museum appropriation available for drawing and we are 

 therefore seriously handicapped in any effort to illustrate our 

 collections. It might be suggested that the investment of even a 

 moderate sum for drawing, pays, not alone because of the 

 increase in scientific value of the specimens so illustrated, but 

 their intrinsic value is thereby greatly exhanced and the Museum 

 is thus substantially and materially the gainer. 



Among the interesting additions to the general collections is a 

 series of fossils from the Corniferous limestone in the towns of 

 Cass and Waverly, Indiana. These have been generously pre- 

 sented to the Museum by Mr. E. H. Eaymour, of Kansas City, Mo., 

 in return for identification of species. The assemblage of species 

 is essentially the same in both these localities and comprises an 

 intermixture of forms, which in the Xew York sections where the 

 faunas are more sharply differentiated, characterize partly the 

 Corniferous limestone, partly the Hamilton shales. The fauna is 

 suggestive of that occurring in the Hydraulic and Encrinal lime- 

 stones, lying above the Upper Helderberg group at the Falls of 

 the Ohio, but the typical Corniferous limestone species are more 

 abundant. It appears to represent both of the faunas men- 

 tioned. The detailed stratigraphy of this region is not reported, 

 but all the material examined from the two localities is identical 

 in lithological structure and fossil contents.
