314 REMARKS.—No material is available; nothing in the description or illustrations argues against the synonymy proposed first by Grube (1866b). Eunice tahitana Kinberg, 1865 Eunice tahitana Kinberg, 1865:562; 1910:42, pi. 16: fig.17. Eunice antennata.—Hartman, 1948:78-79 [in part, not Leodice antennata Lamarck, 1818]. REMARKS.—No material is available in Riksmusect, Stockholm (R. OlerOd, in litt.); when Hartman examined the material, only fragments without an anterior end were left of this species. The species was characterized as having antennae with moniliform articulations and articulated peristomial and notopodial cirri, and branchiae from setiger 4 with up to six filaments. Hartman (1948:79) mentioned that the subacicular hooks were yellow and tridentate; that the aciculae were yellow, tapering and distally slightly curved; and that the compound falcigers were distally bidentate. Eunice tahitana belongs to group C-2, but cannot be adequately characterized without access to fresh material. The species is here considered indeterminable. 186. Eunice tentaculata Kinberg, 1865 FIGURE 107a-d; TABLES 41,42 Eunice tentaculata Kinberg, 1865:562; 1910:41, pi. 15: fig.13. Eunice valenciennesii Grube, 1878b:55.—Hartman, 1948:76-77. MATERIAL EXAMINED.—TWO syntypes, RM 434, 2°30'S, 107°30'E, 88 m. COMMENTS ON MATERIAL EXAMINED.—Both syntypes are in poor condition and the soft parts cannot be illustrated meaningfully. Most of the description is based on the larger of the syntypes. A set of maxillae are present in the vial; it is approximately of the size to be expected for the longer of the two syntypes and is here considered belonging to this species. DESCRIPTION.—One syntype with 9 setigers only, frontally dissected; jaws missing. Other syntype nearly complete with about 75 setigers; length 50 mm. Prostomium apparently frontally rounded; median sulcus shallow. Eyes present. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles with up to 8 long, cylindrical articulations in A-III. A-I to middle of peristomium; A-II to setiger 3 and A-III to setiger 10. Peristomium cylindrical. Separation between rings distinct on all sides; anterior ring 3 A of total peristomial length. Peristomial cirri nearly to frontal margin of prostomium, tapering, with 4 articulations. Maxillary formula 1+1,5+6,7+0,8+9, and 1+1. Mx III long, located behind left Mx II. Mx V very soft, possibly due to poor preservation. Branchiae present, pectinate, not reduced in mid-body region, erecL Branchiae from setiger 6 to setiger 28. Branchiae SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY terminating well before posterior end, present on less than 55% of total number of setigers. First branchiae single filaments; all other branchiae pectinate, with possible exception of last few. Maximum number of filaments 9 according to Kinberg (1865). Shape of neuropodial acicular lobes indeterminable. Ventral cirri inflated in some median setigers. Notopodial cirri medially inflated at least in branchial region. Limbate setae marginally smooth. Pectinate setae with both marginal teeth slightly longer than other teeth; -15 teeth present. Shafts of anterior compound falcigers (Figure 107a) distally inflated, marginally smooth. Shafts of posterior compound falcigers (Figure 107b) barely inflated, marginally distinctly serrated. Anterior appendages tapering, with distinct head, bidentate. Proximal teeth smaller than distal teeth, triangular, directed laterally. Distal teeth sharply tapering, curved. Anterior guards asymmetrically bluntly pointed, marginally smooth; mucros absent. Posterior appendages tapering, with distinct head, tridentate. Proximal teeth smaller than distal teeth, narrowly triangular, nearly tapering, directed laterally. Distal teeth replaced by large, erect shaft terminating in 2 small blunt teeth. Guards symmetrically sharply pointed, marginally serrated; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae (Figure 107d) yellow, tapering, distinctly bent distally; cross-sections round. Separation between core and sheath indistinct in both aciculae and subacicular hooks. Subacicular hooks (Figure 107c) yellow, tridentate with teeth in a crest. Hooks first present from setiger 23, present in all setigers thereafter, single in setiger 23; most setigers with 4 or 5 hooks in dorsoventral row. Hooks tapering to narrow necks and distinct heads. Main fang large, triangular, directed slightly basally; secondary and tertiary fangs on same bases; fangs decreasing evenly in size from main to tertiary fangs. Some hooks with paired protuberances on both sides of main fang appearing as laterally placed additional teeth under certain light conditions. UNKNOWN MORPHOLOGICAL FEATURES.—Most prostomial and peristomial features; parapodial features; all features associated with posterior setigers. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—MX III long; located behind left Mx II. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 58, 59. Unknown Characters: 1-6, 8, 10-12, 14-17, 20, 32, 42-52, 54-56, 60,61,63,64. ASSUMED STATES FOR PURPOSE OF PREPARING KEY — None. REMARKS.—The name E. tentaculata was proposed by Kinberg (1865) for this taxon; a year later Quatrefages (1866) used the same name for a completely different species (for a detailing of problem see Fauchald, 1986); the latter species was renamed E. laticeps by Ehlers (1868). Grube (1878b:55) renamed Kinberg's species, in the mistaken belief that Kinberg's paper was issued after Quatrefages' massive tomes. Hartman (1948) repeated Grube's mistake.
