Abstract: The similarities in external morphology and distribution have made distinction between Aplidium arenatum, Aplidium propinqum and Synoicum parfustis diffficult in the field and laboratory. Quantitative differences have been found between the species in: height and area of the lobe top; the shape, color, and clustering of lobes; the number of systems per lobe; the number of zooids per lobe; the number of zooids per system; zooid size; the number of rows of stigmata; the number of developing embryos in the atrium; and habitat.
