Parts 161-76 are on the genus Chiton. 



Parts 177-84 are on the genus Cardium. 



Parts 185-6 are on the genus BuUnus. 



Parts 187-99 are on the genus Murex. 



Part 200, containing the genus Typhis, with the catalogue of same, 

 and the new title page, dated 1841 (with the table of contents), were 

 issued in this last part, together with the reprinted catalogues of the 

 genera Amphidesma, Bulimis, Cancellaria, Chilina, Ehurna, JEulima, 

 Monoceros, Neritina, and Numla, as the original texts of the above 

 had been printed on smaller paper than the rest of the work. 



The dates of the catalogues given in the table (in the cases where 

 they were afterwards reprinted) are those of the original edition. 



The following notes are printed on the first jxiges of tlie original 

 catalogues of the genera Nucida and Cancellaria, and do not appear 

 in the reprinted ones.

 " These are small bivalves, exceedingly variable in form, but all 

 well characterized bj' an internal ligament and by a series of minute, 

 sharp-pointed teeth, on each side of the ligament, in eacli valve. Very 

 few of them agree in form with that one, which from its resemblance 

 to a little nut, has given rise to their genetic appellation. Tliey do 

 not appear to have excited the attention of Naturalists in any great 

 degree, for Lamarck has only mentioned six recent species. He 

 appears, moreover, to have been very imperfectly ae(][uainted with the 

 characters of the genus; for he speaks of them as forming by their 

 nacreous interior and bj' the situation of the ligament of their valves, 

 an evident transition to the Trigonite. In fact, though several of the
