Non- Cephalothrix nominal species

Table in Appendix 2 summarizes nominal species that are likely contained in the taxon Cephalothrix . Cephalothrix galatheae Dieck, 1874 is retained in the list, because the proboscis is described as lacking stylets, the mouth is illustrated to lie behind the brain ( Dieck 1874: pl. XXI, Figure 16), and the lateral nerve is depicted to be positioned within the body-wall longitudinal muscle layer ( Dieck 1874: pl. XXI, Figure 13), although Coe (1902: 432–433) argued it could be synonymous with the decapod-egg parasitic monostiliferan Carcinonemertes carcinophila (Kölliker, 1845) . Nominal species originally included in Cephalothrix but not listed in Table in Appendix 2 are the following five:
