This is a supplement to volume 7 in this series. From the introduction:
"After the publication of the Catalogo dei Tipi e Degli Esemplari Figurati della Collezione Bellardi e Sacco - Parte I e Parte II all the samples concerning the classes Cephalopoda, Gastropoda, Amphineura, Scaphopoda, described in the Monograph I Molluschi del Terreni Terziarii del Piemonte e della Liguria, volumes 1-22 and additions of volume 30 (Bellardi, 1872-1890; Sacco, 1890-1897, 1904) have been re-arranged and catalogued. The samples that have been catalogued were all those having an original autographic label by Bellardi and/or Sacco or a label bearing the catalogue number attributed to Bellardi and listed in the registers compiled by the author.
To the already listed taxa of the catalogue other 60 have been added, that were described in the monograph and had not been found before. Among these there are 4 new species by Bellardi, 9 by Sacco and 11 taxa, the type material of which was described by Stefano Borson (1820-1825). Moreover, some new figured specimens have been added; they belong to the taxa already included in the catalogue even if not all the original material was found. A part of the new additions come from the lucky finding of a good number of samples of the Rovasenda collection, that were considered destroyed; moreover, with the re-arrangement of the whole material, other types and figured specimens have been recognized and separated from samples that are anonymous or bearing different indications. A total of 131 new figured specimens have been recovered and belong to about one hundred taxa. On the other hand, 21 specimens are missing as far as the catalogue is concerned.
In the following pages there is a list of the additions and the differences found. In Table 1 the newly found specimens considered of particular importance are illustrated, according to the criteria already described in the introductive notes of the catalogue"
