Type species Chamberlin stated clearly the type species was Cirratulus viridis Langerhans (type by original designation). However the type species is as Cirratulus bioculatus Keferstein 1862 in Fauchald, 1977:29 & Day (1967:507), and both of these claims were incorrect. Probably meant as the then current valid name basionym reference, because C. viridis has been synonymised to C. bioculatus in the past. [details]
