Type locality.

close to Svalbard, Norway, Greenland Sea.

Distribution.

Svalbard, Norway, Greenland Sea; depth unknown.

Remarks.

This species has a very deficient description and is represented by very few museum specimens for comparison. The description of C. lloydii by Roule (1905) (see synonymy list) may fit a range of species (e.g., Cerianthus lloydii , Ceriantheopsis americana ) and thus it is not possible to discuss it based on these data. The type locality is difficult to reach, and it may be very problematic to obtain additional specimens due to the absence of precise locality data and because material is likely to be from great depths up to 5000 m ( Ritzmann et al. 2004). Therefore, the validity of this species remains uncertain.
