Remarks. Four species, Eunice cultrifera   n. sp., E. impexa   , E. tubicola ( Treadwell, 1922)   and E. tubifex Crossland, 1904   , have knife-shaped appendages in anterior compound chaetae and bidentate appendages in posterior ones. Eunice tubifex   and E. tubicola   have single subacicular hooks and the color of the hooks closely resembles that of the acicula. In E. impexa   , two subacicular hooks are present in nearly all parapodia along their distribuion and subacicular hooks are lighter in color than acicula in any given chaetiger.

Eunice impexa   has been previously reported from Port Lincoln in Australia ( Zanol et al. 2010). The material from Australia, which originally had been identified as E. tubifex   , all have multiple subacicular hooks lighter than aciculae characteristic of E. impexa   . One additional species, E. schizobranchia   , has dark subacicular hooks lighter than aciculae; however, this species has distally bidentate compound chaetae in all chaetigers.
