For Vaupel-Klein (1970, p.36) the specimen from the Station "P" belongs to a geographical vatiety of M. princeps and that M. ornata as described by Brodsky (1950, p.303, fig.210) must also be regarded as a variety or a subspecies of M. princeps already noticed the close relationship between M. princeps, M; ornata, M. macrura, and M. ignota.
According to Markhaseva (2001, p.48) : probably the distributional range for this species is not so wide (see geographical chart in Razouls & al. 2008), as it could have been mixed with other large-sized Metridia, the taxonomic status of which are not clear.
