Genus Stylina Lamarck, 1816

(= Pseudocoenia d'Orbigny, 1850 , Type species. Pseudocoenia bernardiana d'Orbigny, 1850 , Jurassic of France).

Type species. Stylina echinulata Lamarck, 1816 , Sequanian (Jurassic) of France (Verdun) .

Diagnosis. Colonial, massive, plocoid. Gemmation extracalicinal. Costosepta compact, laterally finely granulated. Columella styliform. Wall septothecal. Endothecal dissepiments tabular. Peritheca vesicular.

Remarks. D'Orbigny (1850) established Pseudocoenia as a genus like ' Stylina lacking a columella' but without designating a type specimen for the type species. Later, Wells (1936) designated a lectotype which, however, turned out to have all characteristics of the genus Stylina Lamarck. Despite the fact that the lectotype differs from the generic concept of Pseudocoenia , the lectotype remains the valid type specimen of the type species of Pseudocoenia . Therefore, Pseudocoenia d'Orbigny, 1850 , represents a junior synonym of Stylina Lamarck.
