 Catalogue names ; or, if descriptions have been published, they are so unsstisfactory as 

 to render it impossible to recognize with certainty the species.

* These Plates contain beautifully executed figures, drawn on stone by Prof. J. \V. 

 Salter, of a number of Crinoids, chiefly from Rocks of the Carboniferous Age of the West- 

 ern States It is unfortunate, however, that a large proportion of the figures represent 

 species previously described by other authors.
