The species was not among the several myo- docopids found by Darby (1965) in the vicinity of Sapelo Island, Georgia. The distribution of S. zostericola is shown in Text-figure 2. Kornicker and Wise (1962) identified the species in collections from coastal lagoons of Texas. The occurrence of disjunct populations of S. zostericola along the eastern Atlantic coast and the southwestern Gulf Coast suggests that the species in the past lived also along the southeastern Atlantic and the northern and eastern Gulf coasts, possibly during colder climates of the Pleistocene. Jones (1958a, 1958b) reported S. zostericola (= S. tricostata Jones, 1958) from San Francisco Bay, California. I compared in detail specimens of the species from Massachusetts, Texas, and California, and could find no dif- ferences (Kornicker, 1967). I propose here that the population in San Fran- cisco Bay was transported along with oysters which were transplanted from the East Coast during the years 1870 to Text-figure 1.

ACKNOWLEDGMENTS I thank Dr. Eric Robinson for sending specimens of S. zostericola from England, Dr. Joseph Hazel for a specimen of S. zostericola from the mouth of the Chesapeake Bay, and Mr. Les Watling for information concerning distribution of the species along the Delaware coast. I thank also the following individuals for information concerning oysters: Dr. Austin B. Williams, Dr. James E. Hanks, Dr. A. F. Chestnut, and Mr. J. Richards Nelson. Dr. M. Pettibone, in addition to criticizing the manuscript, supplied valuable informa- tion concerning the introduction of polychaetes to English waters. I thank also Dr. T. E. Bowman, Dr. I. G. Sohn, and Dr. J. E. Hazel for criticizing the manuscript. The SEM photograph of the ostracode valve
