NUMBER 523 103 diagnostic." As indicated elsewhere, E. barvicensis is similar to E. filamentosa, so presumably the name E. challenged was used by Mclntosh as a manuscript name for another, similar species from the Challenger expedition, which species cannot now be identified and no material is available under this name in BM(NH) (A. Muir, in litt.). 39. Eunice cincta (Kinberg, 1865) FIGURE 30f-h; TABLES 33,40 Nicidion cincta Kinberg, 1865:564; 1910:43, pi. 16: fig. 21. Eunice (Nicidion) cincta.—1 [artman, 1948:80-81. MATERIAL EXAMINED.—Holotype, RM 418, Eimeo, Society Islands, 0.3-1 m, Eugenie Expedition 1159. Kinberg (1865:564) gave the locality information as "Mare pacificum inter corallia mortua tacniarum exteriorum insulac Eimeo, summa aqua vel fundo 1-4 pedum." COMMENTS ON MATERIAL EXAMINED.—The anterior end has been deeply dissected and the shape of the prostomium cannot be determined accurately. The last 15 setigers are extremely poorly preserved. DESCRIPTION.—Holotype incomplete with 65 setigers (last 15 extremely poorly preserved); length through setiger 50 15 mm; maximal width 1.1 mm; length through setiger 10, 3 mm. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles thick and digitiform, wrinkled, but without articulations. All antennae to posterior peristomial ring. Separation between peristomial rings distinct on all sides; anterior ring ~ l /i of total peristomial length. Peristomial cirri to posterior part of anterior peristomial ring, ovate, without articulations. Jaws missing. Branchiae absent. Neuropodial acicular lobes rounded; aciculae emerging at midline. Presetal lobes low, transverse folds. Anterior postsetal lobes following outline of acicular lobes closely, becoming low, transverse folds from about setiger 25. Anterior and median ventral cirri thick, tapering. Anterior notopodial cirri medially inflated, becoming digitiform in last distinct segments in fragment, without articulations. Limbate setae slender, marginally serrated. Shafts of pectinate setae (Figure 300 very slender. Pectinate setae flaring, flaL Both marginal teeth slightly longer than other teeth; -15 teeth present. Shafts of compound falcigers (Figure 30g) distinctly inflated, marginally coarsely serrated. Appendages slender with nearly parallel sides, bidentate. Proximal teeth shorter than distal teeth, sharply pointed, directed basally. Distal teeth slender, directed laterally. Guards asymmetrically bluntly pointed, marginally serrated, without mucros. Pseudocompound falcigers and compound spinigers absent. Aciculae brown, bluntly conical, straight; cross-section round. Subacicular hooks (Figure 30h) brown, bidentate. Hooks first present from setiger 21, present in all setigers thereafter, single at least through median setigers. Hooks with distinctly bent necks. Proximal teeth slightly larger than distal teeth, directed laterally. Distal teeth curved, directed laterally. UNKNOWN MORPHOLOGICAL FEATURES.—Features associated with the posterior setigers and with the poor state of preservation. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 22, 31-42, 54, 55. Unknown Characters: 1, 2, 4, 6-17, 24, 47, 50, 51, 57-60, 63, 74, 78. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice cincta is listed with similar species in Tables 33 and 40. The shape of the subacicular hook resembles the condition in E. mutilata; however, the latter is always branchiated, even as a juvenile. Among the abranchiate species, E. cincta is unusual in that it wholly lacks inflated bases in median ventral cirri. Eunice cingulata Claparede, 1868 Eunice cingulata Claparede, 1868:444-445, pi. 7: fig. 1. Eunice purpurea.—Grube, 1878a:100. REMARKS.—No type material exists of this or any other species of Eunice described by Claparede. The following summary is based on his description. Prostomium deeply bilobed. Antennae short, with moniliform articulations. Anterior peristomial ring very nearly as long as posterior ring. Peristomial cirri to front edge of peristomium, with moniliform articulations. Branchiae present from setiger 8. First few single filaments, all others strongly pectinate; maximum number of filaments unknown. Presumably, branchiae continue to end of body. Limbate setae marginally serrated. Pectinate setae with marginal tooth very much longer and thicker than all other teeth. Shafts of compound hooks inflated. Appendages short, tapering. Proximal teeth triangular. Distal teeth curved. Guards distally asymmetrically bluntly pointed. Aciculae and subacicular hooks with dark cores and clear sheaths; aciculae tapering distally to blunt, gently curved tips. Subacicular hooks tapering to distinct heads. Proximal teeth directed laterally. Eunice cingulata was well characterized by Claparede, who, in addition to the description summarized above, emphasized the dark violet color and the violet-and-white banding of the anterior end and appendages. The species clearly is a member of group B-2, but, based on the available information, cannot be separated from a series of other species. It is here considered indeterminable.
