Introduction begins: "This Catalogue is the continuation and final part of the Literature of the Polychaetous Annelids, of which Volume I, the Bibliography, has been issued (Hartman, 1951a). The Catalogue is an attempt to present in a uniform style the facts of the establishment of the systematic categories applied to the POLYCHAETA or marine annelids. The names of the higher ranks, such as families and subfamilies, are given in alphabetic order, followed by an alphabetic list of generic and subgeneric names, together with the families to which they are referred. Species and lesser categories (subspecies and varieties) are listed alphabetically under family groupings arranged systematically. Fossil names, most numerous in the family SERPULIDAE, are largely omitted."
