Prionospio spp.

Remarks.

Specimens are identified as Prionospio based on the shape of the prostomium (anteriorly rounded, posteriorly extending into a short caruncle), presence of branchiae or branchial scars not earlier than chaetiger 2, and the presence of low dorsal crests. Moreover, sabre chaetae and hooded hooks were usually present. However, most specimens are in poor condition and characters essential for their identification to species level are lost, e.g., mostly anterior fragments, only few branchiae preserved. Other characters observed are very variable. Several species are present according to observed characters (see Suppl. material 2) but remain unidentified.
