| | NMITA Gastropod taxonomic list |
 | | Instead I have placed subgenera (if recognized) in alphabetical order within a genus, genera alphabetically within a family, families alphabetically within superfamilies and so on through to the level of ‘Infraorder’ (e.g. |
 | | Littorinimorpha, Ptenoglossa and Neogastropoda of the ‘Superorder’ Caenogastropoda). |
 | | Hierarchical rank is not specified, though authors and dates are given for families, but relative ranking is shown by font size, bold capitalisation and then, from Order/’Superorder’-levels, by degree of indentation from the margin. |
