Excerpt from A Classed and Annotated Bibliography of the Palæozoic Crustacea, 1698-1892: To Which Is Added a Catalogue of North American Species I am well aware that the value of a work of this kind depends upon the care and labor given to its compila tion. Every possible means of obtaining accurate in formation from a miscellaneous class of literature in many languages has been used, and it is hoped that there are but few errors and omissions.
