Bulla occidentalis A. Adams, 1850 Western Striate Bubble

Bulla occidentalis A. Adams, 1850 Western Striate Bubble

Dredged, Caesar's Creek, Biscayne National Park, South Florida (38 mm.)

    For years regarded as part of an amphi-Atlantic species (Talavera, 1982; Vermeij and Rosenberg, 1993), but Malaquias and Reid (2008), based on DNA sequence data, demonstrated that the eastern Atlantic B. striata Bruguière, 1792 is specifically distinct. Further, they indicated that B. umbilicata Röding, 1798 is invalid (ICZN, 1959: Opinion 549; suppressed for purposes of the Principles of Homonymy and Priority) and that specimens thus identified (e.g., de Jong and Coomans, 1988: 135, pl. 26; Redfern, 2001: 159, pl. 70) are B. occidentalis. Egg capsules and embryonic development illustrated and discussed by Winner (1985).
