The larval development of Megalobrachium soriatum (Say, 1818), a shallow-water western Atlantic porcellanid crab, is completely described and illustrated. Megalobrachium soriatum hatches as a prezoeal stage of less than 1 day's duration, and then molts through two subsequent zoeal stages of about 6 days' duration each, before attaining megalopal stage. Although megalopae remained as such for up to 8 days, none molted to first crab stage. The zoeae and megalopae of M. soriatum are compared with those of two other species of Megalobrachium in which the larval development is known. The larvae of all three species, predictably, share many features in common. However, larvae of M. soriatum are unusual in that they also exhibit features heretofore known only in larvae of some species of Pisidia; a situation all the more remarkable since Megalobrachium is a member of the Petrolisthes-group of larvae while Pisidia is assigned to the Porcellana-group of larvae.
