Asexual reproduction in cirratulids is confirmed or newly reported in: 1) Cirratulus Lamarck (herein restricted to species with wedgeshaped (versus conical) prostomium, two or more dorsal tentacles on one anterior segment together with branchiae, capillary and sigmoid acicular setae): C. incertus Mcintosh, reinstated, and C. gayheadius (Hartman), n. comb.; 2) Timarete Kinberg (restricted to species with wedge-shaped prostomium, dorsal tentacles on several anterior segments after first branchiae, midbody branchiae arising well above notopodia, capillary and sigmoid acicular setae): T. caribous (Grube), T. filigera (delle Chiaje), and T. punctata (Grube); 3) Protocirrineris Czerniavsky (new status, reinstated for species of the Cirratulus chrysoderma complex: prostomium bluntly conical to wedge-shaped; dorsal tentacles few, on several anterior segments after setiger I; branchiae with or without subdistal pads, first present on segments with dorsal tentacles; setae all fine capillaries): P. chrysoderma (Claparede) and P. ?antarctica (Monro), both n. comb.; and 4) Dodecaceria Oersted (5 species). Chaetozone gayheadia Hartman has been confused with other taxa. It is redescribed from types, transferred to Cirratulus and figured for the first time; the holotype is regenerating anteriorly and some of the paratypes show anterior and posterior regeneration, suggesting that asexual reproduction is a normal part of the life cycle. Cirratulus borealis Lamarck is considered distinct; it differs from C. cirratus (0. F. Miiller) in having two branchiae per segment throughout rather than just anterior. Some life-history stages of C. incertus, the Danish species keying out to C. cirratus, are described and figured. Misinterpretation of asexual regenerates has led to needless or misleading descriptions of new taxa.
