Epigamia charcoti (Gravier, 1906) comb. n. (Fig. 85 A–E) Autolytus charcoti Gravier, 1906: 283 –285; 1907: 7–8, pl. 1, fig. 1–2, textfigs 1–2; Benham 1921: 27 –31, pl 5, figs 7–10; 1927: 60.

Not Autolytus charcoti Day 1960: 317 –318; 1967: 283, fig. 12.12 K–N (= Procerini sp). Material examined. Antarctic Sea: 2 syntypes MNHN A 72, Antarctic expedition, 1905. Diagnosis. Epigamia with long alternating dorsal cirri and a trepan consisting of 27 teeth, 1 large alternating with 2 smaller in 2 rings Description. Two anterior fragments, length 35–48 mm for 26–44 chaetigers, width 0.45–0.55 mm. Preserved material yellowish brown, no colour markings. Ciliation as 2 trochs per segment, seen in posterior part of larger fragment. Eyes separated; eye spots absent. Palps in dorsal view projecting 1 / 5 – 1 / 4 of prostomial length, fused. Extension of nuchal epaulettes to end of chaetiger 3 (Fig. 85 A). Median antenna reaching chaetiger 10–14. Lateral antennae and dorsal tentacular cirri, length 2 / 3 of median antenna. Ventral tentacular cirri 1 / 3 as long as dorsal pair. First dorsal cirri as long as median antenna. Second dorsal cirri as long as ventral tentacular cirri. From chaetiger 1–27 cirri with usual alternation in direction, more posterior difficult to assess due to lost cirri. Dorsal cirri from chaetiger 3, alternate in length; short cirri equals 1 / 2–4 / 5 of body width, long cirri 3 / 4 to slightly longer than body width. Cirrophores present on tentacular cirri, and all dorsal cirri. Cirrophores equal, cirrostyles unequal (Fig. 85 A, B); short cirrostyles 1 / 2 – 2 / 3 in length of long cirrostyles; cirrophores shorter than parapodial lobes; cirrophores shorter than cirrostyles. All appendages cylindrical. Parapodial ...
