Fig. 1 in Reinstatement of Perinereis bairdii (Webster, 1884) and description of P. websteri sp. nov. from Bermuda, including the reproductive morphology of two Atlantic Perinereis species (Annelida: Errantia: Phyllodocida)

Fig. 1. Parapodial morphology of species of Perinereis Kinberg, 1865 and points used to obtain segments and length ratios of parapodial structures described in this work. Arrows and labels correspond to points used for the measuring parapodial structures as described in Material and methods section. A. Parapodium from posterior chaetiger of Perinereis floridana (Ehlers, 1868) (ECOSUR P1100). B. Parapodium from natatory region of Perinereis floridana (LACM-AHF 7376). Abbreviations: Dc = dorsal cirrus; DDoL = distal lobe of dorsal ligule; DoL = dorsal ligule; LDc = lower lamella of dorsal cirrus; LoM = lower lamella of median ligule; LVc = lower lamella of ventral cirrus; MeL = median ligule; NeL = neuroacicular ligule; PDoL = proximal lobe of dorsal ligule; PoL = neuropodial postchaetal lobe; PreL = notopodial prechaetal lobe; UDc = upper lamella of dorsal cirrus; UVc = upper lamella of ventral cirrus; Vc = ventral cirrus; VeL = ventral ligule; VeLa = ventral lamella.
