86 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY Type yellow with white punctations, with 96 setigers. Antennae with up to 12 long articulations in A-III. A-I to posterior peristomial ring; A-II to setiger 3; A-III to setiger 5. Branchiae from setiger 3 through setiger 27; all pectinate with up to 9 filaments. Notopodial cirri about as long as branchiae, vaguely articulated. Aciculae yellow. The branchial distribution combined with the information about the antennae and the color of the aciculae indicate that this species might be a member of C-l, but the information is clearly insufficient to identify the species and it is here considered indeterminable. 30. Eunice bipapillata Grube, 1866 Eunice bipapillata Grube, 1866a:64. FIGURE 23; TABLES 27,30, 31 MATERIAL EXAMINED.—Part of holotype, ZMB F 1993b (marked Eunice magnified, see comment below), Samoa, 3 parapodia. COMMENTS ON MATERIAL EXAMINED.—G. Hartwich (in litt.) informed me that parapodial preparations of E. bipapillata and E. magnifica originally were stored together in the same vial; at one time they were split apart into two vials. The three parapodia referred to above agree with E. bipapillata and cannot agree with E. magnifica due to differences in the distribution of branchiae and the different maximal numbers of branchial filaments reported by Grube for the two species. Therefore, it is assumed that the labels for the two vials were confused. The description given below is a summary of observations on the parapodial preparations and the original description. DESCRIPTION.—Type copper-colored with white band across setiger 4. Ceratostyles articulated. Branchiae (Figure 23d,h,i) present, pectinate, distinctly shorter than notopodial cirri, not reduced in mid-body region. Branchiae from setiger 4 to end of body. Branchiae present to near posterior end, present on more than 65% of total number of setigers. Up to 4 filaments from setiger 8 through setiger 18; paired filaments in setiger 77. Branchial stems short, tapering. Filaments digiuform. Anterior acicular lobes (Figure 23d,e) asymmetrically truncate, with aciculae emerging above midline, becoming slightly triangular in posterior setigers (Figure 23i). All pre- and postsetal lobes low folds. Ventral cirri distinctly inflated basally in setigers 15 and 18; inflated base lost by setiger 77; narrow tip digitiform in all setigers. Ventral cirrus in setiger 77 digitiform. All notopodial cirri similar in size and shape; bases slightly inflated, tapering to blunt, digiuform tips, without articulations. Limbate setae longer than other setae, slender, narrowly limbate, marginally serrated. Shafts of pectinate setae (Figure 23b,h) cylindrical, slender; blades slightly flared, flat. One marginal tooth longer than other teeth; up to 15 teeth. Shafts of compound falcigers (Figure 23a,c) tapering, marginally smooth; distal beak indistinct. Appendages short, relatively thickset with large heads, bidentate. Proximal teeth triangular, directed laterally or slightly distally, with distinct distal upturned tip; distal teeth longer than proximal teeth, tapering or blunt, directed obliquely distally. Guards asymmetrically bluntly pointed, without mucros. Pseudocompound falcigers and compound spinigcrs absent. Aciculae paired, black, tapering, straight, blunt-tipped; cross-section round. Subacicular hooks (Figure 230 black, bidentate. Hooks absent in parapodia 15 and 17, present in parapodium 77. Proximal tooth thicker than distal tooth, but no longer, curved, directed laterally. Distal tooth nearly erect, tapering. Guard short, truncate. UKNOWN MORPHOLOGICAL FEATURES.—All features associated with prostomium and pcrisiomium; jaw structure; distribution of branchiae and subacicular hooks. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—Antennae not reaching beyond pcristomium; with cylindrical articulations or without articulations; digitiform. Mx III short; located in front of left Mx IV, forming part of a distal arc. Branchiae continued to far posterior setigers. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 56, 58, 59. Unknown Characters: 1-20, 22-29, 33, 34, 36-40, 51, 52, 74, 78, 80-82. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—20,3; 22,2; 23,4; 33,2; 37,1; 38,1. REMARKS.—Eunice bipapillata is listed with similar species in Tables 27, 30, and 31; it resembles in certain respects E. aphroditois, but cannot be completely identified without access to more material. Eunice bitorquata Grube, 1870 Eunice bitorquata Grube, 1870b:56. Eunice siciliensis.—Grube, 1878a: 101. REMARKS.—The original description contains the following statements (K. Fauchald translation): The species is brown with golden to brown cross bars on the peristomium. Branchiae are present from setiger 104 and are present only as single filaments, far outreaching the notopodial cirri. Segments are remarkably short and the median antenna is as long as four segments. The maxillae have coarse teeth; Mx II has 4 teeth. Grube (1878a: 101) referred this species questionably to his own Eunice siciliensis, but gave no comment or any supportive statements. The original description is wholly inadequate to characterize the species; the information given is consistent with the synonymy suggested by Grube (1878a), but is not sufficient to be conclusive. Eunice bitorquata is here considered indeterminable.
