As there appear to be section and subsections in the second and third
units (Shells and Fossils) of this book, Tables of Contents were
created for the electronic edition. A number of the images were moved
where they split paragraphs. There is a reference to a Figure 24 for
Ancylus; but no Fig. 24 was included. The reference to Fig. 26 for
Bullidae was assumed to be a reference to Fig. 14. Bulla ampulla.
With the exception of the following items, all page number references
in the original text were retained. There are references to two tables
on Page 77. The first was listed a "vide Table, p. 16" and the second
as "vide Table, p. 32" which appear to refer to the tables on page 78
and 94 respectively. The page references were corrected.
Species name are assumed to be correct for the time of publication
(ca. 1886). For example, Charychium is today listed as Carychium.
