96 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY than peristomium, less than V2 as deep as peristomium. Prostomial lobes frontally rounded, dorsally excavate with thickened rim; median sulcus deep, directed ventrally. Eyes not observed. Antennae in a shallow horseshoe, evenly spaced; A-III slimmer than other antennae. Ccratophorcs long in all antennae, without articulations. Ccratostyles digiliform, without articulations. No antennae reaching beyond first peristomial ring; A-I shortest; A-III longest, but difference in length less than one-third of length of longest antenna. Peristomium flared anteriorly, with distinct, muscular lower lip. Separation between rings distinct on all sides; anterior ring ~ 2 /3 of total peristomial length. Peristomial cirri to posterior ! /3 of first peristomial ring, without articulations, tapering, less than half as long as A-I. Jaws now missing. Maxillary formula 1+1, 3+3, 6+0, 6+4, and 1+1 according to Trcadwell (1921:56). Branchiae (Figure 28d) present, palmate, distinctly longer than notopodial cirri, not reduced in mid-body region, erect. Branchiae from setiger 18 to end of fragments. Branchiae present to near posterior end, present on more than 65% of total number of setigers. First 3 branchiae single filaments; most branchiae with paired filaments; in a posterior fragment up to 3 filaments present. Branchial stems very short and truncate. Filaments long, strap-like. All neuropodial acicular lobes asymmetrically truncately rounded; aciculae emerging above midline. All presetal lobes low folds. All postsetal lobes free, rounded to truncate projecting lobes, visible behind acicular lobes. First 20 ventral cirri thick, tapering. Median ventral cirri moderately inflated basally; narrow tips digitiform. Posterior ventral cirri tapering, digitiform. Notopodial cirri of first setiger short, digitiform, without articulations. All other notopodial cirri basally inflated, without articulations. Limbate setae longer than all other setae, coarse, gently curved, marginally serrated. Shafts of pectinate setae (Figure 28f) cylindrical, slender; blades flared, flat. Both marginal teeth slightly longer than other teeth; total of -15 teeth present. Shafts of compound falcigers (Figure 28e) distinctly inflated, internally striated, marginally nearly smooth, with distinct distal beak. Appendages long, tapering; head large, bidentate. Proximal teeth triangular, directed laterally; distal teeth slightly shorter than proximal teeth, sharply tapering, directed laterally. Guards symmetrically rounded, marginally smooth, without mucros. Pseudocompound falcigers and compound spinigers absent. Aciculae (Figure 28b) single, with dark cores and clear sheaths, tapering towards blunt, slightly curved tips. Subacicular hooks (Figure 28c) with dark cores and clear sheaths, bidentate (nearly bifid). Hooks first present from setiger 34, present in all setigers thereafter, always single (except for replacements). Hooks tapering abruptly just below head. Proximal teeth narrower than distal teeth; both teeth directed distally. UKNOWN MORPHOLOGICAL FEATURES.—Presence and position of eyes; relationship between Mx III and left Mx IV; pygidium and anal cirri. EXPECTED STATE OF UNKNOWN MORPHOLOGICAL FEA- TURES.—Mx III short, forming part of distal arc with left Mx IV. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 22, 56, 58, 59. Unknown Characters: 1,2, 13, 14, 36,40, 42. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice bucciensis was considered a synonym of E. afra by Hartman (1956). In E. bucciensis branchiae arc palmate with very long filamcnLs; in E. afra branchiae arc distinctly pectinate. The antennae lack articulations in E. bucciensis and have distinct, cylindrical articulations in E. afra. Eunice bucciensis is listed with similar species in Tables 33 and 39. Among the species in Table 39, E. bucciensis and E. denticulata stand out for having elevated, long ccratophorcs. Eunice bucciensis has A-III slimmer than the other antennae and branchiae first present from sctiger 18; in E. denticulata, all antennae arc similar and branchiae are not present until sctigcr 27. Eunice burmeisteri Grubc, 1878 Eunice (Marphysa) Burmeisteri Grubc. 1878a: 101. REMARKS.—Grubc listed this species as a possible synonym of Marphysa sanguinea and indicated that it was named by Fritz Miillcr in a letter to him. As far as can be ascertained, no description of the species was ever issued, nor does any material exist. Due to the reference by Grube (1878a) of the possible synonymy with Marphysa sanguinea, the species must be considered indeterminable rather than a nomen nudum; the issue will be considered further in a planned review of the genus Marphysa. 36.

DESCRIPTION.—Holotype complete with 90 setigers; last 7 in regeneration; total length 103 mm; maximal width 6 mm at setiger 10. Length through setiger 10, 14 mm. Body ventrally flattened, dorsally moderately inflated throughout, slightly wider in branchial region than in postbranchial region, abruptly tapering anteriorly, slowly tapering posteriorly; regenerating end abruptly narrower than remainder of body. Anal cirri slender, digitiform, without articulations. Prostomium (Figure 29a) distinctly shorter and narrower than peristomium, less than x li as deep as peristomium.
