Remarks.

This species was initially described from the Italian coast (Naples region) as a variation of Cerianthus membranaceus ( Andres 1881). However, Lo Bianco (1909) recognized distinct differences from the material identified as C. membranaceus and suggested a new name, Cerianthus dohrni , but without giving a description. Subsequently, van Beneden (1924) gave a very detailed morphological description of the species with some observations from specimens in aquaria. Some years later, Torelli (1932) described Cerianthus viridis based on specimens with a morphology clearly related to that of Cerianthus dohrni . Carlgren (1940) relocated C. dohrni to the genus Pachycerianthus . This is one of the largest species of tube-dwelling anemones in the world with a length of more than 40 cm, which is comparable to the lengths of Ceriantheomorphe brasiliensis and Cerianthus membranaceus .

Type material.

Not designated (several specimens mentioned, which can be considered syntypes).
