204 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY rounded; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae and subacicular hooks black; subacicular hooks present in second half of body and either uni- or bidentate. Schmarda's illustration of the jaws is so confused that no maxillary formula can be recorded. He must also have missed the first several pairs of simple branchiae and stated that branchiae were from setiger 12 where the strongly pectinate complex branchiae start according to his illustration. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: Unknown Characters: 3-20, 23-26, 28-29, 33, 36-38, 40, 42-65, 67, 74-76, 78, 80-82. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—33,2; 37,1; 38,1. REMARKS.—Augener (1918) synonymized Eriphyle capensis Kinberg (1865 = Eunice kinbergi Ehlers, 1868) with this species, but rejected the synonymy of both with E. aphroditois as proposed by Mclntosh (1905). All three species belong to the same group, B-2, and are rather similar. Mclntosh's synonyms have been generally accepted (e.g., Day, 1967). The species are here listed separately in Tables 27 and 30, because resolution of this problem will have to await studies of morphological variability in material of E. aphroditois from Indian Ocean. Eunice macrobranchia has not been included in the key. Eunice macrobranchia is supposed to have either simple, spine-like or bidentate subacicular hooks. For that reason it is also listed with other species with simple subacicular hooks in Table 50. Because it is so poorly known, it cannot be clearly separated from other species in this table. Eunice macrochaeta Schmarda, 1861 Eunice macrochaeta Schmarda, 1861:128, 6 figs. REMARKS.—Schmarda (1861:128) stated that the type and apparently only known specimen lacked the anterior end. The species is thus wholly unidentifiable. Grube (1878b: 101) referred the species under doubt to the genus Marphysa based on the illustration of the branchiae. Hartman (1944:107) referred the species, again doubtfully, to E. filamentosa, following suggestions by Augener (1925). The structure of the setae as illustrated by Schmarda (1861:128) agree with E. filamentosa, except that the characteristic hammer-headed aciculae of that species were not illustrated. The species is here considered indeterminable. Eunice madeirensis Baird, 1869 Eunice madeirensis Baird, 1869:344-345. REMARKS.—Examination of the type material demonstrated that this species has the jaw structure and setal complement of the species in the genus Pcdola. 111. Eunice magellanica Mclntosh, 1885 FIGURE 68a-f; TABLES 27.29 Eunice magellanica Mclntosh, 1885:265-268, fig. 28, pi. 37: figs. 12-15, pi. 19A: figs. 6-9. MATERIAL EXAMINED.—TWO syntypes, BM(NH) ZK.1885.12.1.191, and slide preparation, ZK.1885.12.1.191a. Challenger sta 311, Magellan Strait, north of Isla Desolation, 52°50'S, 73°53'W,448 m, mud, 11 Jan 1876. COMMENTS ON MATERIAL EXAMINED.—Unless otherwise indicated, the description is based on the larger of the two syntypes. DESCRIPTION.—Larger of 2 syntypes complete female with eggs in body cavity with 130 setigers; total length 140 mm; maximal width 7 mm; length through setiger 10, 17 mm. Small syntypc complete (in 2 pieces) with 108 sctigcrs; total length 78 mm; maximal width 5 mm; length through sctigcr 10, 11 mm. Prostomium (Figure 68a) distinctly shorter and narrower than pcristomium, less than '/.• as deep as pcristomium. Prostomial lobes short, frontal ly rounded; median sulcus deep. Eyes posterior to bases of A-I, black. Antennae evenly spaced, similar in thickness. Ccratophores ring-shaped in all antennae, without articulations. Ceratostylcs digitiform, with up to 5 irregular articulations in A-I 11. A-I barely to middle of anterior peristomial ring; A-I I to posterior peristomial ring; A-I 11 to setiger 2. Peristomial fold deep, covering bases of antennae; peristomium flaring slightly ventrally; lower lip muscular. Separation between rings distinct dorsally and ventrally; anterior ring 4 /5 of total peristomial length. Peristomial cirri of large syntype very short, ovate, to middle of peristomium in small syntype, without articulations. Two sets of maxillae present in vial, both of roughly same size, either one could belong to large syntype; small syntype not dissected. One maxillary formula 1+1, 6+6, 8+0, 8+10, 1+1, and 1+1. Other maxillary formula 1+1, 7+7, 8+0, 7+9, 1+1, and 1+1. Both maxillae with Mx III forming part of distal arc with left Mx IV. Mx VI with distinct teeth in both sets of jaws. Branchiae (Figure 68e) present, pectinate, distinctly longer than notopodial cirri, not reduced in mid-body region, erect. Branchiae from setiger 7-8 to setiger 120. Branchiae present to near posterior end, present on more than 65% of total number of setigers. First branchiae with 2 filaments, increasing to 5 filaments at about setiger 20. From about setiger 70-75 number of filaments increasing rapidly to 20 at setiger 85; this number continued to setiger 115 in large syntype. Some filaments irregularly branching. Reduction in size and numbers of filaments in far posterior setigers very rapid. Where best developed branchial stems thick, somewhat coiled, and so branchiae may appear palmately, rather than pectinately branched. Neuropodial acicular lobes distally truncate or rounded; aciculae emerging at midline. All pre- and postsetal lobes low,
