224 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY was first described. It is listed with similar species in Tables 33 and 36. Eunice pruvoti and E. modesta both have single filaments in all branchiae. Branchiae are continued to the posterior end in the former and are missing on the last 10 setigers in the latter. Eunice modesta is further characterized by the relatively light color of subacicular hooks and aciculae. Eunice monilifer (Chamberlin, 1919) Leodice monilifer Chamberlin, 1919b:ll-12. Eunice enteles.—Hartman, 1938:97 [not Leodice enieles Chamberlin, 1918]. Eunice antennata.—Ruiman, 1944:115-117, pi. 7: figs. 154-156 [in part, not Leodice antennota Lamarck, 1818]. REMARKS.—This species was originally described nestling in kelp hold-fasts near Laguna Beach, California. The type was deposited at the Museum of Comparative Zoology according to Chamberlin, but is now missing (A. Johnston, pers. comm.). The description given here summarizes information given by Chamberlin, with updated terminology. Antennae short, with up to 12 moniliform articulations. Penstomial cirri much shorter than pcristomium and wrinkled or distinctly articulated. Maxillary formula 1+1,4+6,8+0,9+9, and presumably 1+1. Branchiae from setiger 7 to setiger 30 (of 109 setigers in complete type specimen), with maximum 3 filaments. No mention was made of any parapodial or setal features, except that notopodial cirri were characterized as being wrinkled, but not distinctly divided into articulations. Hartman (1938:97) stated that Chamberlin's information about branchial distribution was unreliable. She illustrated tridentate hooks in a specimen of Eunice from Laguna Beach, but did not specify branchial distribution in the specimen she illustrated. In other members of groups C-l and C-2, differences in branchial distribution such as the one separating E. enteles from E. monilifer in similar-sized specimens is considered highly significant The two forms cannot be synonymized with each other, however, neither one is sufficiently well characterized to allow positive identification. Eunice monilifer is here considered indeterminable. Eunice mossambica Peters, 1854 Eunice mossambica Peters, 1854:612.

Nauphanta mossambica.—Fauchald, 1987:376-378, fig. la-e. REMARKS.—Originally described in Eunice and usually considered a member of Marphysa, this species was moved to the genus Nauphanta by Fauchald (1987). 125. Eunice mucronata Moore, 1903 FIGURE 75a-e; TABLES 9,41,45 Eunice mucronata Moore, 1903:437-440, pL 25: figs. 42-45. MATERIAL EXAMINED.—Lectotype, USNM 15851, and 11 paralectotypes USNM 5341, Albatross sta 3698, Japan, Sagami Bay, 4.5 miles SE of Manazuru Saki (~35°O8'N, 139° 10Ti), 278 m, green mud, volcanic ash and sand, beamtrawl. COMMENTS ON MATERIAL EXAMINED.—The lectotype was isolated as USNM 15851; this specimen and one complete specimen with 111 setigers from USNM 5341 had been dissected by Moore. The.description is based on the specimen from 15851. DESCRIPTION.—Lectotype complete, with 116 setigers; total length 58 mm; maximal width 4 mm at about setiger 25; length through setiger 10, 8 mm. Body cylindrical, tapering relatively slowly towards both ends. Prostomium (Figure 75a) distinctly shorter and narrower than pcristomium, less than '/2 as deep as pcristomium. Prostomial lobes frontally rounded, dorsally inflated; median sulcus shallow. Palpal region distinguished by transverse frontal furrows. Eyes posterior to bases of A-1, very large, brown, not clearly visible in all specimens. Antennae in a horseshoe, with A-I isolated by a gap, similar in thickness. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles slender and tapering to very narrow tips without articulations. A-I apparently articulated in some specimens due to irregular muscle contractions rather than structural features. A-I to setiger 2; A-I I to setiger 10; A-III to setiger 13. Peristomium cylindrical. Separation between rings distinct on all sides; anterior ring ~ 2 h of total penstomial length. Peristomial cirri attached at extreme frontal edge of posterior penstomial ring, reaching beyond tip of prostomium, same length as A-I, slender and tapering, without articulations. Summary maxillary formula for 2 syntypes 1+1, 7-8+7-8, 7-8+0, 6+8, and 1+1. Syntype from USNM 5341 with consistently lower numbers of teeth where numbers differ. Branchiae (Figure 75c) present, pectinate, distinctly longer than notopodial cirri, not reduced in mid-body region, erect. Branchiae from setiger 3 to setiger 34; in other syntypes last branchiae on setigers 29-33. Branchiae terminating well before posterior end, present on less than 55% of total number of setigers. First 2 pairs single filaments; maximum 15 slender filaments. Branchial stems slender, erect. Anterior neuropodial acicular lobes distally truncate or rounded, becoming distinctly triangular posteriorly; aciculae emerging above midline. Pre- and postsetal lobes low, transverse folds. First 3 ventral cirri thick, tapering. Ventral cirri basally inflated in branchial region. Inflated bases ovate; narrow tips tapering. Postbranchial ventral cirri increasingly slender, tapering, resembling notopodial cirri closely, but consistently shorter. All notopodial cirri slender, tapering, with gently inflated bases, without articulations. Notopodial cirri long in prebranchial region, becoming shorter through branchial region, so in last of branchial setigers notopodial cirri no longer than branchial filaments. Postbranchial notopodial cirri about half as long as those in prebranchial region. Limbate setae slender, marginally smooth. Pectinate setae
