(Scale bars in mm.)
NUMBER 523 143 shorter than filaments. Filaments digitiform, shorter than notopodial cirri. Anterior neuropodial acicular lobes symmetrically truncate, becoming asymmetrically rounded with aciculae emerging above midline. Prcsetal lobes low, somewhat asymmetrical folds with low side ventrally. Postsetal lobe low asymmetrical folds with low side dorsally. Ventral cirri thick and rounded in all setigers, developing long digitiform tips in posterior setigers present, possibly distorted in fixation. Anterior notopodial cirri short, inflated, becoming longer posteriorly, but retaining distinct inflated basal section, without articulations. Limbate setae slender, marginally smooth. About 5 pectinate setae in a parapodium. Pectinate setae tapering, flat. Marginal teeth about as long as other teeth, with 15 teeth. Shafts of compound falcigcrs (Figure 46d) gently inflated, marginally smooth; beaks indistinct. Appendages large; heads large, bidentate. Teeth similar in size. Proximal teeth narrowly triangular, directed laterally. Distal teeth tapering, directed obliquely distally. Guards asymmetrically bluntly pointed, marginally serrated; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae (Figure 46e) paired, yellow; exposed portion twisted in double curve, sharp tipped; distal end when worn slightly knobbed; cross-section round. Separation between core and sheath indistinct in both aciculae and subacicular hooks. Subacicular hooks (Figure 46c) yellow, tridentate with teeth in tandem. Hooks first present from setiger 27, present in all setigers thereafter, always single (except for replacements). Shafts strongly curved distally, tapering. Two lower fangs, including largest and smallest arranged on either side of middle fang, which clearly outreach other fangs. UNKNOWN MORPHOLOGICAL FEATURES.—Jaw structure; characters associated with posterior setigers, including branchial distribution; pygidium and anal cirri. EXPECTED STATES OF SELECTED UNKNOWN FEATURES.— Mx III long, located behind left Mx II. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 51, 54, 55. Unknown Characters: 1, 2, 13, 14, 33, 36-38,40,47, 50, 57-60,63. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice flaccida was considered a synonym of E. antennata by Crossland (1904:312). It may be a member of either group C-l or C-2, because the type is posteriorly incomplete; thus it has been included in Tables 41 and 44 as well as in Tables 46 and 49. It has tridentate hooks with the teeth in tandem as does E. elseyi in addition to two species with dark subacicular hooks; these are compared in Tables 52 and 53. It differs from E. elseyi in that it has distally entire aciculae and bidentate compound falcigers; in E. elseyi the aciculae are bidentate and the compound hooks distally tridentate. 66. Eunice flavapunctata (Treadwell, 1922) FIGURE 46f-j; TABLES 33,39 Leodice flavapunctata Treadwell, 1922:136-138, figs. 8-11, pi. 2: fig.1-7. Eunice qfra.—Hartman, 1956:282 [not Eunice afra Peters, 1854]. MATERIAL EXAMINED.—Holotype, AMNH 1532, Breaker Point, Pago Pago, Samoa, 1920. COMMENTS ON MATERIAL EXAMINED.—The anterior end has been deeply dissected frontally and the illustration of the anterior end is a reconstruction (all antennae were present however). DESCRIPTION.—Holotype incomplete, of unknown sex, with 80 setigers; length 47 mm; maximal width 2 mm at setiger 10; length through setiger 10, 7 mm. Prostomium (Figure 460 about as long as peristomium, about as wide as peristomium, as deep as peristomium. Prostomial lobes frontally rounded, dorsally inflated; median sulcus deep. Eyes not observed. Antennae in transverse row; A-I separated by gap from A-II and A-III, similar in thickness. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles digitiform, irregularly wrinkled, without articulations. A-II and A-III similar in length, barely outreach peristomium. Peristomium cylindrical. Separation between rings distinct on all sides; anterior ring ~ 2 h of total peristomial length. Peristomial cirri barely reaching beyond posterior peristomial ring, digitiform, without articulations. Jaws now missing. Branchiae present, pectinate, distinctly longer than notopodial cirri, not reduced in mid-body region, erect. Branchiae from setiger 13 to end of fragment. Maximum 6 filaments, reached at about setiger 50. Most segments with 2 or 3 long, digitiform filaments (Figure 46j). Branchial stems cylindrical, shorter than notopodial cirri. Branchiae located well above neuropodial cirri on body wall. Neuropodial acicular lobes truncate; aciculae emerging above midline. Pre- and postsetal lobes low folds. First 4 ventral cirri tapering, nearly digitiform. Ventral cirri basally inflated from about setiger 5; bases inflated in all remaining parapodia. Inflated bases thick, transverse welts; narrow tips tapering. Anterior notopodial cirri relatively short, digitiform, becoming increasingly slender and longer in branchial region; articulations absent. Limbate setae long, narrowly limbate, marginally dentate. Shafts of pectinate setae (Figure 46h) wide, cylindrical. Blades narrow, tapering, flat. One marginal tooth very much longer than other teeth, with 10 narrow, slender teeth. Shafts of compound falcigers (Figure 46i) inflated, marginally serrated; beaks distinct. Appendages short; heads large, bidentate. Proximal teeth larger than distal teeth, narrowly triangular, directed obliquely distally. Distal teeth abruptly tapering, directed obliquely distally. Guards symmetrically rounded, marginally serrated; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae black, tapering to narrow tips, straight; cross-sections round. Subacicular hooks (Figure 46g) black, bidentate. Hooks first present from setiger 25, present in all setigers thereafter, always single (except for replacements). Hooks tapering, curved. Proximal teeth very much larger than distal teeth, directed laterally. Distal teeth blunt, directed nearly laterally. UNKNOWN MORPHOLOGICAL FEATURES.—Jaw structure;
