274 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY with 61 setigers; length 31 mm; maximal width 2 mm; length through setiger 10,4.5 mm. Prostomium (Figure 91i) distinctly shorter than peristomium, about as wide as peristomium, as deep as l /i of the peristomium. Prostomial lobes frontally rounded, dorsally flattened; median sulcus shallow. Eyes between bases of A-I and A-I I, black. Antennae in a horseshoe, evenly spaced. Ceratophores long in all antennae, without articulations. All ceratostyles missing. Peristomium cylindrical. Separation between rings distinct on all sides; anterior ring somewhat more than 72 of total peristomial length. Peristomial cirri missing. Jaws missing. Branchiae present, pectinate, distinctly longer than notopodial cirri, not reduced in mid-body region, erect. Branchiae from setiger 5 to setiger 33. Branchiae terminating well before posterior end. First branchiae single filaments; all others pectinate with up to 9 filaments at about setiger 12. Branchial stems slender, erect. Filaments long, slender. Neuropodial acicular lobes distally truncate; aciculae emerging at midline. Pre- and postsetal lobes low, transverse lobes. First 2 ventral cirri tapering. Ventral cirri basally inflated from setiger 3 through setiger 35. Inflated bases nearly spherical; narrow tips tapering. Posterior ventral cirri thick and tapering. Notopodial cirri slightly inflated basally, without articulations. Notopodial cirri without articulations. Limbate setae marginally finely serrated. Pectinate setae (Figure 91k) very slender, tapering, flat. One marginal tooth longer than other teeth; 5-7 long, slender teeth present. Shafts of compound falcigers (Figure 91j) distally slightly inflated, marginally smooth. Appendages long, narrow, bidentate. Proximal teeth triangular, directed basally. Distal teeth nearly erect in anterior appendages, sharply curved in median appendages. Guards tapering to sharp tips, mucronate. Pseudocompound falcigers compound spinigers absent. Aciculae numbering 2 or 3, yellow, tapering, straight; cross-section round. Subacicular hooks (Figure 911) yellow, tridentate with teeth in a cresL Hooks first present from setiger 18, present in all setigers thereafter, usually single, rarely paired. Main fang very large, curved; secondary and tertiary fangs in crests; especially tertiary fang very small. UNKNOWN MORPHOLOGICAL FEATURES.—Structure of ceratostyles; jaw structure; features associated with posterior setigers; pygidium and anal cirri. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 56, 58, 59. Unknown Characters: 1, 2, 4, 6, 17, 20-23, 27-29,38,47, 50, 63. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—38,2. REMARKS.—Eunice prayensis was considered synonymous with E. vittata by Hartman (1948:77). It belongs to group C-l, as does E. vittata, and is listed with similar species in Tables 41-45. Kinberg (1865:563) described the antennae as follows: "Appendices lobi cephalici breves nee moniliformes; tentacula media et impar segmentum 3 non attingentia, aequalia." (prostomial appendages short and not moniliform; A-I I and A-III do not reach third segment and are equal). Assuming that antennal articulations were cylindrical, the most probable comparison is between E. prayensis and species listed in Table 42. The subacicular hooks are occasionally paired, but are certainly not present in a vertical series as in E. vittata and a few similar species in Table 45. The only other species with such distribution of the subacicular hooks in Table 42 is £. flavocuprea. Eunice flavocuprea has maximally four branchial filaments and the 10 last pairs of branchiae are single filaments; E. prayensis has maximally nine filaments and the branchiae have at least two filaments in the last branchiae present Kinberg stated that branchiae should be present from setiger 3; this cannot be confirmed. Note that the notopodial cirri of setigers 3-4 are damaged, and branchiae may have been present. Eunice procera Grubc, 1866 Eunice procera Grube, 1866b:68; 1878a:100. REMARKS.—According to the original description, E. procera has branchiae starting on setiger 22 and continued to far posterior end with a maximum of 11 filaments at setigers 59-72. Grube (1878a: 100) in addition, by the placement of the species in his review, implied that the species should lack articulations in the ceratostyles. No specimens are available and the information is clearly insufficient to characterize the species. It is here considered indeterminable. 162.

MATERIAL EXAMINED.—Holotype, BM(NH) ZK 1885.12.1.192, off Ascension Island, 7°54'20"S, 14°28'20"W, 768 m, volcanic sand, Challenger sta 344, 3 Apr 1876. COMMENTS ON MATERIAL EXAMINED.—The holotype is currently in two pieces and the anterior end has been deeply dissected. The specimen is otherwise in good condition. DESCRIPTION.—Holotype complete with 122 setigers; total length 80 mm; maximal width 7.5 mm; length through setiger 10, 16 mm. Prostomium (Figure 92d) distinctly shorter and narrower than peristomium, less than l /2 as deep as peristomium. Prostomial lobes frontally rounded, dorsally inflated; median sulcus shallow. Peristomial fold large, covering bases of antennae and eyes at bases of A-I I. Antennae in a horseshoe, with A-I isolated by a gap, similar in thickness. Ceratophores
