FIGURE 78.—Eunice mulilaioides (holotype, ZMB 6397): a, pectinate seta, parapodium 95; b, subacicular hook,
parapodium 95; c, compound falciger, parapodium 95. Eunice narconi (syntype, BM(NH) ZB 1972.73): d,
subacicular hook, about parapodium 50; e, acicula, about parapodium 50; f, pectinate seta, about parapodium 50;
g, compound falciger, about parapodium 50. (Scale bars in mm.)
determined. First 7 ventral cirri tapering. Ventral cirri long
ventrolateral ridge in median setigers; narrow tips tapering.
Posterior ventral cirri tapering. Notopodial cirri apparently
short, medially inflated. Notopodial cirri without articulations.
Limbate setae marginally smooth. Pectinate setae (Figure
78a) long, slender, tapering, furled. One marginal tooth
distinctly longer than other teeth; -10 teeth present. Compound
falcigers (Figure 78c) small. Shafts inflated, marginally
serrated. Appendages short with relatively large heads, bidentate.
Proximal teeth tapering to sharp, curved tips. Distal teeth
abruptly tapering, directed laterally. Guards asymmetrically
bluntly pointed, following outline of hooks closely; mucros
absent. Pseudocompound falcigers and compound spinigers
absent. Aciculae tan-colored, tapering to blunt tips, straight;
cross-sections round. Subacicular hooks (Figure 78b) light to
dark tan color, bidentate. Hooks first present from setiger 19,
present in all setigers thereafter, always single (except for
replacements). Hooks with distinct heads. Proximal teeth large,
directed laterally. Distal teeth about as long as proximal teeth,
slender, directed obliquely distally.
