FIGURE 117.—Eunice woodwardi (holotype, BM(NH) ZH 1863.8.19.13): a, anterior end, lateral view; b,
compound falciger, parapodium 45; c, acicula, parapodium 45; d, subacicular hook, parapodium 45. (Scale bars
in mm.)
postbranchial region. Notopodial cirri without articulations.
Limbate setae rather wide and marginally finely serrated.
Pectinate setae not observed. Shafts of compound falcigers
(Figure 117b) tapering, marginally smooth. Appendages large
with distinct heads, bidentate. Proximal teeth larger than distal
teeth, triangular, directed slightly basally. Distal teeth curved.
Guards symmetrically rounded with a distinct mucro, marginally
serrated. Pseudocompound falcigers and compound spinigers
absent. Aciculae (Figure 117c) paired, yellow, tapering
and bent dorsally; cross-sections round. Separation between
core and sheath indistinct in both aciculae and subacicular
hooks. Subacicular hooks (Figure 117d) yellow, tridentate with
teeth in a crest Hooks first present from setiger 31, present in
all setigers thereafter, most postbranchial setigers with 4 to 5
hooks in each segment. Hooks with large main fangs; distal pair
of fangs in a crest.
UNKNOWN MORPHOLOGICAL FEATURES.—Jaw structure;
pygidium and anal cirri.
EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA-
TURES.—None.
