MATERIAL EXAMINED.—One syntype, MNHN, Paris, Kuts, Ile de Pino, Nouvelle Caledonie, 1928, coll. Mme Pruvot; 1 syntype, MNHN, Paris, Collection Francais, Nouvelle Caledonie, forme jeune no. 10.

COMMENTS ON MATERIAL EXAMINED.—Both syntypes are currently labeled Eunice afra, and the labels are in Pierre Fauvel's handwriting; the second specimen also has a label naming it as “?Eunice jeune no. 10.” The small syntype is nearly translucent, slender, and narrow and not distinctly dorsally flattened; the anterior end has been deeply dissected and the jaws are now missing. The description is based on the larger of the syntypes.

DESCRIPTION.—Large syntype complete, of unknown sex, with 115 setigers; total length 34 mm long; maximal width 3 mm; length through setiger 10, 5 mm. Anterior body cylindrical, becoming dorsally flattened and rather wide with crowded setigers by setiger 10; posterior end abruptly tapering and flattened. Anal cirri as long as the last 15 setigers, without articulations. Small syntype complete, of unknown sex, with about 100 setigers; total length 22 mm; maximal width 1 mm wide; length through setiger 10, 3 mm.

Prostomium (Figure 92f) distinctly shorter than peristomium, distinctly narrower than peristomium, less than as deep as peristomium. Prostomial lobes frontally truncate, dorsally somewhat flattened; median sulcus deep. Palpal regions set off by horizontal, frontal grooves. Eyes between bases of A-I and A-II, large, dark. Antennae in a horseshoe, evenly spaced, similar in thickness. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles thick, sausage-shaped, digitiform, with 1 or 2 cylindrical, distinct articulations. Antennae to middle of anterior peristomial ring. Peristomium slightly flaring anteriorly, with distinct, muscular lower lip. Separation between rings distinct dorsally and ventrally; anterior ring ~ of total peristomial length. Peristomial cirri to posterior end of anterior peristomial ring, digitiform, without articulations.

Jaws not examined.

Branchiae (Figure 92j) single filaments, present from setiger 15 to setiger 115. All branchiae distinctly longer than notopodial cirri, strap-like, proximally flattened, nearly as long as half body width in median and posterior setigers. Branchiae present to near posterior end, present on more than 65% of total number of setigers.

Median acicular lobes distally rounded with aciculae emerging at midline. Pre- and postsetal lobes low, transverse folds. Anterior ventral cirri thick, tapering, becoming basally modestly inflated by setiger 10, retaining inflated bases through most of body. Bases ovate or spherical; narrow tips tapering. Far posterior ventral cirri tapering, rather slender. Prebranchial notopodial cirri tapering, basally slightly inflated, becoming digitiform in branchial region; all notopodial cirri short, rather inconspicuous, without articulations.

Limbate setae slender, marginally smooth. Pectinate setae (Figure 92k) flaring, flat. One marginal tooth distinctly longer than other teeth, with ~15 teeth. Anterior setigers with 2–3 pectinate setae; median and posterior setigers with up to 25 pectinate setae. Shafts of compound falcigers (Figure 921) distally inflated, marginally smooth, with distinct distal beaks. Appendages short, tapering, with rather large heads, bidentate. Proximal teeth triangular, directed laterally. Distal teeth distinctly shorter than proximal teeth, distinctly bent, distally blunt. Guards symmetrically rounded, marginally serrated; mucros absent. Pseudocompound falcigers and compound spinigers absent. Neuropodial aciculae single, light brown, tapering to blunt, straight tips; cross-sections round. Subacicular hooks (Figure 92f) light brown, bidentate. Hooks first present from setiger 19, present in all setigers thereafter, always single. Hooks tapering narrow heads. Teeth directed distally; both teeth similar in size.

COMMENTS ON ADDITIONAL SPECIMEN EXAMINED.—Antennae of small syntype short, without articulations.

Branchiae absent.

Shafts of compound falcigers (Figure 92h) inflated, marginally smooth. Appendages very short. Guards symmetrically rounded. Teeth slender. Proximal teeth longer than distal teeth, narrowly tapering, directed laterally. Distal teeth tapering, directed laterally. Subacicular hooks (Figure 92i) from about setiger 25. Hooks with narrowed necks and distinct heads. Both teeth directed distally and similar in size.

UNKNOWN MORPHOLOGICAL FEATURES.—Location of maximum width and width at setiger 10. Condition of dorsal edge of pygidium. Jaw structure.

EXPECTED STATES OF SELECTED UNKNOWN FEATURES.—Mx III forming arc with left Mx IV; Mx VI absent.
