The Liguus of South Florida and the Florida Keys

The southernmost areas of the Florida peninsula, including the Florida Keys, are inhabited by one of the most varied population of tree snails of the genus Liguus. All of the described subspecies, color forms and varieties are listed and shown, grouped according to Pilsbry's work, on photo webpages as part of this website.

A revised Grouping/Listing of the Florida Liguus
following the taxonomy proposed by Pilsbry 1946,
"Land Mollusca of North America"

This listing is based upon the work of Pilsbry which in turn is a synthesis of his earlier work, Simpson’s work, McGinty’s work and the work of William Clench. The work is revised to include new discoveries, descriptions post 1946 and some correction as a result of newer information.

DISCUSSION AND INFORMATION

At the end of each photo page there is a discussion section which lists
Type locality, Holotype number and depository, Paratype number and depository
and Description publication information for each taxa on that page. An abbreviation
page is provided for Museum/Institutions and Publications @ Abbreviation Page

Note: The easy way out of taxonomic uncertainties is to place all of the Florida Liguus into
one species, Liguus fasciatus, with an alphabetical list of unrelated color forms.
Your choice; use the above grouping (Pilsbry) or use a list of color forms.
