Eunice gravieri Fauvel, 1911:14–15, figs. 1a–b, 2a–d; 1914:145–146, pl. 10: figs. 1–4 and 11–18.

DESCRIPTION.—The types are not available. Fauvel's two descriptions are detailed and suffice to characterize the species.

Types two small specimens, one incomplete, other 28 mm long and 2 mm wide (presumably with parapodia); numbers of setigers not mentioned but must have exceeded 50.

Prostomium frontally rounded. Two pairs of eyes; 1 between bases of A-I and A-II and 1 pair posterior and slightly medial to other pair, hidden under peristomial fold. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles slender and digitiform, with up to 6 long, cylindrical articulations in A-III (as illustrated, not moniliform as stated by Fauvel). A-II and III to setiger 8. Peristomium apparently a single ring. Peristomial cirri very slender and digitiform, reaching well beyond frontal edge of peristomium, articulated (Fauvel's illustrations conflict with his text).

Maxillary formula 1+1, 6+7, 7+0, 6+10, 1+1, and 1+1. Mx V and VI reduced. Mx III part of distal are with left Mx IV.

Branchiae present, single filaments, distinctly shorter than notopodial cirri. Branchiae from setiger 5 to setiger 20 or 26. Branchiae terminating well before posterior end. Filaments digitiform.

Ventral cirri basally inflated in branchial region, tapering in anterior and far posterior setigers. Notopodial cirri digitiform, vaguely articulated, at least through branchial region.

Pectinate setae narrow. One marginal tooth very long, stout, with ∼10 teeth. Shafts of compound falcigers tapering or slightly inflated, marginally smooth. Appendages relatively short, with large heads, bidentate. Proximal teeth triangular, slightly tapering, directed at various angles. Distal teeth either gently curved and slender or thick with distinct bends. Guards symmetrically bluntly pointed; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae dark, tapering, pointed, straight in anterior setigers, bent in posterior setigers; cross-sections round. Subacicular hooks dark, bidentate. Hooks first present from setiger 25. Hooks strongly curved, with distinct inflated region just below heads. Proximal teeth larger than distal tooth, directed laterally. Distal tooth directed obliquely distally.

UNKNOWN MORPHOLOGICAL FEATURES.—Numerous features from all parts of the body.

EXPECTED STATES OF SELECTED UNKNOWN FEATURES.—Species too poorly known to allow predictions.
