During the progress of the work it became necessary to 

 introduce descriptions of a considerable number of hitherto 

 undescribed species, which were needed in order to give com- 

 pleteness to the generic discussions and illustrations. These 

 descriptions are included in supplements ; one at the completion 

 of the discussions of the Inarticulate Brachiopods, and the other 

 at the close of the book. 



The s])ecies there described for the first time are :
