188 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY SCORED.—Inappropriate Characters: 56, 58, 59. Unknown Characters: 1,2,4,6, 13, 14, 42,47, 50,63. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice kobiensis was considered a synonym of E. websteri (as E. longicirrata Webster) by Imajima and Hartman (1964:256); as already indicated by Fauchald (1969), the proposed synonymy cannot be correct. Eunice kobiensis is compared to similar species in Tables 19 and 20. Fauchald (1969) compared it to a number of similar species; at this time nothing can be added to that comparison and to discussions of other species listed in Table 20. 99. Eunice langi (Treadwell, 1943) FIGURE 61j-o; TABLES 24,26 Leodice langi Treadwell, 1943:3, figs. 14-18. Eunice savignyi.—Hartman, 1956:283 [not Eunice savignyi Grube, 1878]. MATERIAL EXAMINED.—Holotype, AMHN 3739, Cape Town, South Africa. COMMENTS ON MATERIAL EXAMINED.—The anterior end has been badly mangled and partly dissected, and all antennae are lost, so no illustrations were attempted of the anterior end. DESCRIPTION.—Holotype complete, of unknown sex, with 71 setigers; total length 42 mm; maximal width 2 mm; length through setiger 10, 5.5 mm. Prostomial lobes frontally obliquely truncate, dorsally flattened; median sulcus shallow. Eyes not observed. Ceratophores ring-shaped in all antennae. Ceratostyles missing. Peristomial rings distinct dorsally and ventrally; anterior ring 3 A of total peristomial length. Peristomial cirri to setiger 3, with 6 distinct articulations. Maxillary formula 1+1,6+5,9+0,6+8, and presumably 1+1 according to Treadwell (1943, fig.18). Branchiae (Figure 61k) present, pectinate, distinctly longer than notopodial cirri, not reduced in mid-body region, erect. Branchiae from setiger 3 to setiger 39. Maximum 8 filaments at or near setiger 15; most branchiae with 4 or 5 filaments. Stems stout, strongly tapered, shorter than notopodial cirri. Filaments digitiform, about as long as notopodial cirri. Anterior neuropodial acicular lobes distally truncate; posterior acicular lobes (Figure 61j) obliquely conical; aciculae emerging at midline. Pre- and postsetal lobes low, transverse folds. First 4 ventral cirri very long, digitiform, as long as notopodial cirri. Ventral cirri basally inflated from setiger 5 to setiger 36, with distinct, digitiform, obliquely attached tips. Inflated bases increasing evenly from setiger 5 to setiger 15, ovate, decreasing from setiger 30, missing posterior to setiger 36. Posterior ventral cirri short, nearly tubercular. Anterior notopodial cirri slender, digitiform; posterior notopodial cirri long, tapering. Notopodial cirri without articulations. Shafts of pectinate setae (Figure 61m) slender, cylindrical. Blades flat, strongly flaring. One marginal tooth longer than other teeth, with -15 teeth. Shafts of compound falcigers (Figure 611) gently inflated, marginally smooth. Appendages long, tapering; heads very small, bidentate. Proximal teeth much smaller than distal teeth, very short, triangular, directed laterally. Distal teeth tapering, nearly erect. Guards asymmetrically sharply pointed; mucros absent. Pscudocompound falcigers and compound spinigers absent. Aciculae (Figure 61n) single, amber-colored, tapering, distinctly bent in median and posterior setigers; cross-sections round. Subacicular hooks (Figure 61o) amber colored, bidentate. Hooks first present from setiger 30, present in all setigers thereafter, always single (except for replacements). Hooks tapering; heads small, distinctly curved. Proximal and distal teeth similar in size. Proximal teeth directed laterally, blunt. Distal teeth truncate, directed laterally. UNKNOWN MORPHOLOGICAL FEATURES.—Prostomial features; relationship between Mx III and left Mx IV; pygidium and anal cirri. EXPECTED STATES OF SELECTED UNKNOWN FEATURES.— Mx III short; forming a distal arc with left Mx IV. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 56, 58, 59. Unknown Characters: 4, 6, 10-17, 19-24, 39-40,74, 78. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—21,2. REMARKS.—The compound falcigers of E. langi resemble those of E. tubifex, but compound spinigers are absent in E. langi. The aciculae and subacicular hooks are amber colored, rather than clear yellow; by definition this places the species in B-l as defined by Fauchald (1970). It is listed with similar species in Table 24 and 26. Eunice langi was considered synonymous with E. savignyi by Hartman (1956); it differs by having considerably darker subacicular hooks and acicula. In addition the latter have branchiae from setiger 4 through setiger 45 with a maximum of 12 filaments; E. langi has branchiae from setiger 3 through setiger 39 with a maximum of eight filaments. Due to the indeterminate status of E. savignyi, other differences or similarities cannot be detailed at this time. None of the character states listed in Table 26 are unique to this species. Among species listed in Table 24, it is characterized first and foremost by the very poor development of the head of the compound falcigers and the sharply pointed, but not mucronate, hood of these hooks. 100.

(Scale bars in mm.) tentaculata is an incomplete specimen that currently is in three 81 segments; length 126 mm; maximal width 10 mm; length fragments. In addition a small posterior fragment with a through setiger 10, 21 mm. Anterior fragment with first 38 pygidium is present; its relation to the type cannot be setigers. determined. Prostomium (Figure 62a) distinctly shorter and narrower DESCRIPTION.—Holotype incomplete, of unknown sex, with than peristomium, less than x /i as deep as peristomium.
