Introduction
In Florida there are seven species of the family Subulinidae. All are introduced and most are well established in many metropolitan areas. Virtually nothing is known about the behavior and life histories of these species (but see Dundee, 1970 for an account on Lamellaxis gracilis). However, Rumina decollata (Linnaeus, 1758) is presently being utilized as a biological control agent of the brown garden snail in California (Fisher and Orth, 1985). The other subulinids also may be part-time carnivores. Rumina decollata was dealt with in a previous circular (Auffenberg & Stange, 1986) and will not be discussed further. The following account provides an identification guide and summarizes present distributions.
