Preliminary report on the Enchytraeidae (Oligochaeta) of West Florida the same-sized area, number of sites and size of sample), but the number of species per sample was lower than in either of the other countries. It is concluded that species distribution in western Florida is very patchy. Possible reasons for this patchiness are discussed.

At the 27 m station . is part of a complex and well developed benthic community. Temporal variation in this species was highly correlated to that of other major taxa (bivalves, ophiuroids).
