In a recent publication (“Anthozoen des rheinischen Mittel-devon,” 1889) Professor Schlüter has put forward the conclusion that the genus Syringolites, Hinde, is identical with the much older genus Roemeria, Edwards & Haime, the former name thus becoming a mere synonym. From this conclusion I feel obliged to dissent, and I propose to show in the following brief communication that Roemeria and Syringolites are distinguished by important morphological characters, and that the latter is fully entitled to generic rank.
