NUMBER 523 83 in 120-150 m depth. The specimen was not available; the description below is summarized from the original description. DESCRIPTION.—Holotype (and only specimen) incomplete, with 50 setigers; total length 12 mm; maximal width 1 mm. Ceratostyles slender and digitiform, articulated, especially distally, with long, cylindrical articulations, becoming apparently drop-shaped distally. A-III to setiger 10. Two pairs of peristomial cirri present; outer pair to posterior end of prostomium; medial pair somewhat shorter. Branchiae present, palmate. Branchiae from setiger 3 through setiger 48. Maximum number of filaments 2. Limbate setae illustrated as marginally smooth. Pectinate setae absent. Shafts of compound falcigers inflated. Appendages small, linear, bidentate. Proximal teeth triangular, distal teeth slender, curved. Guards illustrated as symmetrically sharply pointed, but not mucronate. Pseudocompound falcigers and compound spinigers absent. Aciculae yellow, tapering to blunt tips and distally curved. Subacicular hooks yellow, trideniate with teeth in a crest. Hooks first present from setiger 45. Two distal teeth emerging from common base. UKNOWN MORPHOLOGICAL FEATURES.—Shape features associated with pro- and peristomium; jaw structure (but see comments below); all parapodial features; setal distribution and shapes must be confirmed; pygidium and anal cirri. EXPECTED STATES OF SELECTED UNKNOWN FEATURES.— The species is too poorly known to make meaningful predictions. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: None known. Unknown Characters: 1, 2, 4-19, 24-26, 28, 29, 32-34, 37-68,74,75,78,81,82. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Rullier considered the peristomium as two asetigerous segments; the distribution of branchiae and subacicular hooks has been recalculated to the conventions used in this paper; thus the numbers will not agree with those originally stated. The jaws appear to be highly unusual. Rullier specifically stated that maxillae were absent and that the whole apparatus consisted of two pairs of mandibles. The illustration, seen from the ventral side, shows a pair of very slender forceps and a pair of curved, medially excavated lateral pieces fused to a narrow carrier in the midline posteriorly; the dorsal and distal ends of each half are strongly denticulated with very small, even teeth. These jaws resemble those of juvenile eunicids and onuphids. The structure of the jaws as illustrated and the other features specified indicate that Rullier had a juvenile specimen, perhaps anteriorly damaged, suggested by the doubled peristomial cirri, of group C-l orC-2. Eunice bicirrata is here considered a juvenile, possibly indeterminable. It is listed with similar species in Tables 41 and 42 and in Tables 46-48. It is too poorly known to be included in the key. The description of a new species based on a juvenile does not, per se, make the taxon invalid. 28.

Eunice grubei Hartman, 1956:282 [not Eunice grubei Gravier, 1900]. MATERIAL EXAMINED.—Holotype, AMNH 1527, Suva, Fiji, Apr 1920, coll. A.L. Treadwell. DESCRIPTION.—Holotype complete male with 137 setigers; total length 217 mm; maximum width 7 mm at setiger 15. Length through setiger 10,17 mm; width at setiger 10,6.5 mm. Anterior body cylindrical with strongly convex dorsum, becoming ventrally flattened in median setigers and dorsoventrally flattened in posterior setigers. Anterior end truncate, tapering slowly posteriorly. Prostomium (Figure 21g) distinctly shorter than and narrower than peristomium, less than x ji as deep as peristomium. Prostomial lobes frontally rounded, dorsally inflated; median sulcus deep. Eyes not seen. Antennae in a horseshoe, evenly spaced, similar in thickness. Ceratophores ring-shaped, without articulations. Ceratostyles tapering; basal 73 without articulations; styles increasingly articulated in median l /i and articulations distinctly moniliform in distal x h of each antenna. A-I to middle of peristomium; A-II and A-III to setiger 1; maximally -10 articulations. Peristomium cylindrical. Separation between rings distinct ventrally and at bases of peristomial cirri; anterior ring 3 A of total peristomial length. Peristomial cirri to middle of first peristomial ring, thick and tapering, with about 7 short, moniliform articulations. Jaws missing; according to Treadwell, maxillary formula 1+1,5+5, 6+0, +8, and 1+1. Branchiae (Figure 21h,i) present, pectinate, distinctly longer than notopodial cirri, not reduced in mid-body region, erect. Branchiae from setiger 3 to setiger 132. Branchiae present to near posterior end, present on more than 65% of total number of setigers. First and last 5 branchiae single filaments; maximum number of filaments 7 reached at setiger 10, thereafter number of filaments decreasing slowly; by setiger 100 (Figure 21h) only 2 filaments left. Branchial stems thick, tapering, shorter than filaments. Filaments digitiform. Anterior neuropodial acicular lobes short, asymmetrically truncate or rounded with aciculae emerging well above midline; median and posterior acicular lobes broadly asymmetrically truncate. All pre- and postsetal lobes low, continuous folds. Anterior ventral cirri digitiform in 3 first setigers. Ventral cirri strongly inflated from about setiger 4. Inflated bases spherical; narrow tips digitiform. Inflation decreasing posterior to setiger 60; far posterior ventral cirri digitiform. All notopodia tapering with 2 or 3 cylindrical articulations. Limbate setae longer than other setae, marginally serrated. Pectinate setae (Figure 211) very small; shaft cylindrical, narrow; blades flat, flared. One marginal tooth longer than other teeth; -20 very fine teeth. Shafts of compound falcigers (Figure 21j) tapering, internally striated, marginally smooth,
