Since the original description of Smaragdia viridis (Linnaeus, 1758), considerable disagreement has aris- en regarding the identity of the Mediterranean and Ca- ribbean populations of this species. Some workers ac- cepted S. viridis as a single amphi-Atlantic and Eu- ropean species (Gmelin, 1791; Weinkauff, 1867; Gabb, 1872; Martens, 1879; Tryon, 1888; Pilsbry, 1922; Baker, 1923; Abbott, 1974; Nordsiek, 1982; Dance, 1990; Poppe and Goto, 1991; Barash and Danin, 1992; Rios, 1994; Unabia, 1996). Although Maury did not consider the Dominican fossil to be a subspecies of S. viridis, other authors have considered the Recent and fossil western Atlantic populations to be a subspecies of S. viridis (S. viridis viridemaris Maury, 1917); (Woodring, 1928; Warmke and Abbott, 1961; Schel- tema, 1971; Jong and Coomans, 1988; Loch, 1994). A Recent population of S. viridis from the western At- lantic was also named as a subspecies (5. viridis weys- sei Russell, 1940) based on color pattern differences between the Caribbean and European populations. Russell (1940) noted that the pattern of black lines is ". . found in almost 100%.. ." of the European spec- imens, whereas the "...
