272 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY |NK RGURE 91.—Eunice polybranchia (lectotype, YPM 2731): a, anterior end, lateral view; b, appendage of compound falciger, parapodium 75; c, subacicular hook, parapodium 75; d, pectinate seta, parapodium 75; e, parapodium IS, anterior view; f, pectinate seta, parapodium IS; g, compound falciger, parapodium 15; h, parapodium 75, anterior view. Eunice prayensis (syntype, RM 428): i, anterior end, lateral view; j, compound falciger, parapodium 25; k, pectinate seta, parapodium 25; 1, subacicular hook, parapodium 25. (Scale bars in mm.)

Inflated bases reduced from about setiger 50; ventral cirri gradually displaced to posterior face of neuropodia, directed dorsally behind acicular lobes. In last setigers present ventral cirri thick, tapering. Notopodial cirri digitiform, without articulations. Posterior notopodial cirri curved over next posterior intersegmental furrows. Limbate setae slender, marginally smooth. Pectinate setae (Figure 91d,f) flaring, furled. One marginal tooth distinctly larger than other teeth; 15 teeth present. Shafts of compound falcigers (Figure 91g) inflated, marginally serrated. Appendages (Figure 91b,g) tapering; heads distinct, bidentate. Proximal and distal teeth similar in size in anterior and median setigers; proximal teeth longer than distal teeth in posterior setigers. Proximal teeth triangular, directed laterally. Distal teeth gently curved. Guards symmetrically bluntly pointed; mucros absent. Pseudocompound falcigers and compound spinigers absent Notopodial aciculae slender, brown. Aciculae paired, with dark brown to black cores and clear sheaths, tapering, gently curved, considerably more prominent in posterior than in anterior setigers; cross-section round. Subacicular hooks (Figure 91c) with dark brown to black cores and clear sheaths, bidentate. Hooks first present from setiger 24-36 (29 and 30 in 2 syntypes described), present in all setigers thereafter, always single (except for replacements). Proximal tooth twice as large as distal teeth, directed laterally. Distal teeth nearly erect. UNKNOWN MORPHOLOGICAL FEATURES.—Pygidium anal cirri. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—None. and CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 22, 56, 58, 59. Unknown Characters: 1,2,4, 6, 36-38,40,47, 50, 63. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—37,1; 38,1. REMARKS.—Verrill (1880) discussed material from a series of Fish Hawk stations (865-895). The species was described in a footnote on page 358. The paragraph to which the footnote is attached discusses hard-bottom fauna from a series of stations, "especially from stations 865-867," but no particular station is mentioned as the type locality for the species. For that reason, all material identified by Verrill as Leodice polybranchia from Fish Hawk stations 865-895 must be considered syntypes and are treated as such here. In order to stabilize the description, a lectotype has been designated above. Eunice polybranchia resembles E. norvegica as first noted by Verrill (1880), and is listed with this and other similar species in Table 27. In contrast to E. norvegica it lacks antennal articulations and is listed with other species with which it shares this features in Table 28. It is the only species in that table to combine long peristomial cirri with having A-III distinctly longer than A-II. 161.

MATERIAL EXAMINED.—Two syntypes, RM 428, Atlantic Ocean, Rio de Janeiro, Eugenie Expedition. Kinberg (1865:563) gave locality information as "Portus ad Praya grande juxta Rio Janerio." DESCRIPTION.—One headless fragment of 42 setigers, probably starting at setigers 3-5. Other syntype incomplete,
