192 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY erect. Branchiae from setiger 3 to setiger 184 (five setigers before pygidium). Branchiae present to near posterior end, present on more than 65% of total number of setigers. First branchia single filaments; maximum 10 filaments at about setiger 15. Stems short, flexible. Filaments slender, longer than stems. Neuropodial acicular lobes rounded; aciculae emerging at midline. Pre- and postsetal lobes low, transverse folds. Anterior ventral cirri tapering, becoming basally inflated by setiger 10. Inflated bases modest, ovate, completely reduced by setiger 35; narrow tips tapering. Posterior ventral cirri broadly attached forming shallow open scoops covering lower edge of neuropodia. Notopodial cirri long, tapering to slender digiuform tips, with 4 to 5 articulations anteriorly and 3 to 4 articulations posteriorly. Limbate setae narrow, marginally smooth. Pectinate setae (Figure 63e) tapering, flat. One marginal tooth longer than other teeth, with -15 very slender teeth. Shafts of compound falcigers (Figure 63d, 0 tapering, marginally coarsely serrated, internally striated. Appendages narrow, tapering towards small head, bidentate. Proximal teeth very much smaller than distal teeth, nearly button-shaped, directed laterally. Distal teeth tapering, directed obliquely distally. Guards asymmetrically bluntly pointed, marginally smooth; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae mostly paired, dark brown or black, tapering to blunt tips, slightly curved; cross-sections round. Subacicular hooks (Figure 63g) dark brown to black, bidentate. Hooks first present from setiger 32-33, present in all setigers thereafter, always single (except for replacements). Hooks tapering to small head. Proximal teeth very much larger than distal teeth. Both teeth directed distally. Subacicular hooks darker than aciculae. UNKNOWN MORPHOLOGICAL FEATURES.—Pygidium and anal cirri. EXPECTED STATES OF SELECTED UNKNOWN FEATURES.— None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 56, 58, 59. Unknown Characters: 4,6, 74, 78. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Grube (1870a) indicated that the type material contained specimens of two previously known taxa. As indicated above, one lot consists of an unidentifiable arabellid; the remaining material currently present under this name in MNHN, Paris, appears to belong to a single species in group B-2. The fragment from no. 49a agrees with the other two specimens in structure of parapodia and setae. Eunice laurillardi is listed with similar species in Tables 27 and 32. Of the three species with 10 or more branchial filaments listed in Table 32, E. bowerbanki has A-III distinctly longer than A-II; A-II and III are similar in length in E. laurillardi; the length of A-III is unknown in E. multipectinata. The peristomial cirri reach the middle of the prostomium in E. laurillardi and the middle of the peristomium in E. multipectinata. 102. Eunice leptocirris Grube, 1870 Eunice leptocirris Grube, 187Ob:55. FIGURE 64a-f; TABLES 22.23 MATERIAL EXAMINED.—Holotype, ZMH V-795, Fiji Islands. DESCRIPTION.—Holotype incomplete, of unknown sex, with 141 setigers; length 110 mm; maximal width 3 mm; length through setiger 10, 9 mm. Body cylindrical, with very prominent notopodial cirri. Prostomium (Figure 64a) distinctly shorter and narrower than peristomium, as deep as '/2 of peristomium. Prostomial lobes frontally obliquely truncate, dorsally slightly flattened; median sulcus deep. Eyes not observed. Antennae in horseshoe; A-I and A-II separated from A-III by gap, similar in thickness. Ccratophorcs long in all antennae, without articulations. Ccratostylcs slender and digitiform, without articulations. A-I to posterior peristomial ring; A-II to setiger 6; A-III to setiger 9. Peristomium cylindrical. Separation between peristomial rings distinct on all sides; anterior ring - 2 /s of total peristomial length. Peristomial cirri reaching well beyond tip of prostomium, slender and tapering, without articulations. Jaws not examined. Branchiae (Figure 64b) present, pectinate, distinctly shorter than notopodial cirri, not reduced in mid-body region, erect. Branchiae from setiger 3 to end of fragment. Maximum 6 filaments at about setiger 15. Stems tapering, slender, shorter than filaments. Filaments slender, nearly filiform, shorter than notopodial cirri. Neuropodial acicular lobes rounded or slightly triangular, aciculae emerging above midline. Pre- and postsetal lobes low, transverse folds. First 4 ventral cirri thick, tapering. Ventral cirri basally inflated from about setiger 5. Inflated bases modest, ovate, very long, distally obliquely truncate tips present through median seugers. Inflation gradually lost from about setiger 60; posteriormost ventral cirri slender and digitiform, distally obliquely truncate. Notopodial cirri very long, distally tapering to very slender tips; bases modestly inflated, especially in anteriormost setigers; articulations absent. Limbate setae slender, marginally smooth. Pectinate setae (Figure 64e) tapering, flaL One marginal tooth longer than thicker than other teeth, with -10 teeth. Shafts of compound falcigers (Figure 64c) slightly inflated, marginally smooth; beaks distinct. Appendages slender, with distinct heads, bidentate. Proximal teeth smaller than distal teeth, narrowly triangular, directed laterally. Distal teeth slender, strongly curved, directed laterally. Guards asymmetrically bluntly pointed, marginally smooth; mucros absent. Pseudocompound falcigers and compound spinigers absenL Aciculae (Figure
