1 6 The Paleontologist. Sept. 14. 



S. plicata, James, was dropped long ago; it is not in James' Catalogue of 1875. 



Ceramopora Ohioensis is credited in the list to James; should be Nicholson. 



Favosites gothlandica. Lam, is placed as found in the Cincinnati Groups which is very 

 doubtful. 



There are in the list not less than two names of new Genera and over tiventy-five new 

 species, of which no descriptions or figures have yet been published ; consequently, 

 according to accepted rules, they are not recognized as established Genera and species. 

 The reading of descriptions before scientific bodies is not admitted as sufficient to authorize 

 their recognition. 



Another defect in the list, rendering it less valuable for reference, is the failure to 

 arrange species alphabetically. 



We are aware of the difficulties in compiling a list of this kind, but some, at least, of 

 the mistake mentioned, ought to and might have been avoided, we think.
