Echinolittorina placida Reid, 2009 Interrupted Periwinkle
Be sure to review Echinolittorina of Florida for full explanation for obsolete and current names of species found in Florida. Ref: Reid, D.G., 2009. The genus Echinolittorina Habe, 1956 (Gastropoda: Littorinidae) in the western Atlantic Ocean. Zootaxa 2184: 1-103. Aug. 6.
Based upon Reid's work, we have four similar
Echinolittorina, now in subgenus Amerolittorina,
in Florida to deal with, as follows:
E. angustior (Mörch, 1876)
E. jamaicensis (C. B. Adams, 1850)
[formerly E. riisei (Mörch, 1876)]
E. placida Reid, 2009
[formerly E. interrupta (C. B. Adams in Philippi, 1847)]
E. ziczac (Gmelin, 1791)
