230 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY specimens from USNM 16880 and from setiger 45 in holotype, present in all setigers thereafter, always single (except for replacements). Hooks tapering, bent laterally towards distal; heads distinct. Proximal teeth very much larger than distal teeth, distally curved, laterally directed. Distal teeth nearly erecL UNKNOWN MORPHOLOGICAL FEATURES.—Pygidium. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 56, 58, 59. Unknown Characters: 4,6, 15,23,42. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice multipectinata is listed with similar species in Tables 27 and 32. It is first and foremost characterized by gracile, strongly pectinate branchiae and slender, digitiform antennae and notopodial cirri; the subacicular hooks start rather late, compared to the two other species listed in Table 32 with 10 or more branchial filaments. 128. Eunice murrayi Mclntosh, 1885 FIGURE 76j; TABLES 41,45 Eunice murrayi Mclntosh, 1885:288-289, figs. 48, 49, pi. 39: figs. 7, 8, pi. 20A: figs. 19, 20. MATERIAL EXAMINED.—Holotype, BM(NH) ZK 1885.12.1.201, Simon's Bay, Cape of Good Hope, dredged, 33 m, Dec 1873. DESCRIPTION.—Holotype complete with 101 setigers; total length approximately 37 mm; maximal width 4 mm; length through setiger 10, 7 mm. Anal cirri long, articulated. Prostomium (Figure 76j) distinctly shorter and narrower than peristomium, as deep as 1 /i of peristomium. Prostomial lobes frontally rounded, dorsally flattened; median sulcus shallow. Eyes not seen. Antennae in a horseshoe, evenly spaced, similar in thickness. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles tapering, with moniliform articulations; complete left A-II with 8 articulations; incomplete A-III with 10 articulations. A-I to setiger 1; A-II to setiger 3; incomplete A-III currently to setiger 3; however, apparently originally longer than A-II. Peristomium cylindrical. Separation between rings distinct dorsally and ventrally; anterior ring 3 A of total peristomial length. Peristomial cirri to frontal margin of peristomium, with 3 articulations of which basal ones more than half of total cirral length. Maxillary formula 1+1,5+5, 5+0,5+8, and 1+1. Mx III long, positioned directly behind left Mx II. Branchiae present, pectinate, distinctly longer than notopodial cirri, not reduced in mid-body region, erect. Branchiae from setiger 5 to setiger 28. Branchiae present to near posterior end, present on less than 55% of total number of setigers. Two first and last 5 branchiae single filaments, maximum; 9 filaments at about setiger 10. Branchial stems strong, stiff. Filaments arranged in a neat comb, relatively short. All neuropodial acicular lobes distally truncate; aciculae emerging at midline. All pre- and postsetal lobes low, transverse folds. Prebranchial ventral cirri digitiform. Between setigers 5 and 30 ventral cirri basally moderately inflated. Inflated bases ovate; narrow tips digitiform. Posterior ventral cirri increasingly digitiform, increasing in length, by setiger 50 as long and prominent as notopodial cirri. All notopodial cirri medially inflated, similar in length. Prebranchial cirri with 3 or 4 articulations; articulations increasingly indistinct posteriorly; most notopodial cirri in branchial region with single articulation; postbranchial notopodial cirri without articulations. Nearly all setae broken. Shape of limbatc and pectinate setae and aciculae currently indeterminable. Mclntosh (1885, pi. 20A: fig. 19) illustrated shafts of compound falcigcrs as mildly inflated. Appendage large with both teeth well developed, distinctly curved. Guards blunt; mucros absent. Pseudocompound falcigcrs and compound spinigers absent. Aciculae yellow, distally pointed; cross-sections round. Separation between core and sheath indistinct in both aciculae and subacicular hooks. Subacicular hooks yellow, tridentate with teeth in a crest. Hooks first present from setiger 17. UNKNOWN MORPHOLOGICAL FEATURES.—Many setal features; 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: 4,6, 13,14,23, 65-68, 81, 82. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice murrayi has been considered a synonym of E. australis, which it resembles in distribution of branchiae and in shape of the subacicular hooks. It is listed with similar species in Tables 41 and 45. It resembles E. prayensis in having the separation between the peristomial rings distinct on all sides, but differs from the it in having the notopodial cirri articulated in the anterior end; in E. prayensis the notopodial cirri lack articulations. 129.

Jousseaume and Coutiere, 1897. COMMENTS ON MATERIAL EXAMINED.—The description is based on the shorter of the two syntypes. DESCRIPTION.—Both syntypes complete; one with 196 setigers; total length 95 mm; maximal width 6 mm; length through setiger 10, 8 mm.
