(Scale bars in mm.)
NUMBER 523 121 Anterior neuropodial acicular lobes (Figure 37e) broadly asymmetrically truncate with aciculae emerging near upper edge; small elevated tabs present superior to acicula; median and posterior acicular lobes without the elevated tabs (Figure 37a). All presetal and postsetal lobes low folds. Anterior ventral cirri thick and tapering, becoming basally inflated from about setiger 10. Inflated bases elongated transverse welts; narrow tips tapering. Inflated bases reduced from about setiger 65 and absent from about setiger 85. Posterior ventral cirri short and digitiform. Anterior notopodial cirri long and digitiform, becoming slender in branchial region, but retaining similar length throughout, without articulations. Limbate setae narrow and marginally frayed. Pectinate setae (Figure 37g Jc) narrow, tapering and furled. Both marginal teeth thicker and slightly longer than other teeth; -12 teeth present. Shafts of compound falcigers (Figure 37i) distally inflated, some marginally serrated, others with smooth margins. Appendages (Figure 37b,i) slender, varying in length, bidentate. Proximal teeth very much larger than distal teeth, directed laterally or slightly basally. Distal teeth short and bent. Guards distally symmetrically rounded; mucros absent. Pseudocompound falcigers and compound spinigers absent. All aciculae single; anterior aciculae dark yellow, darkening to brown from about setiger 15, distally slightly expanded, slightly hammer-headed (Figure 37f,l), bent towards anterior end; cross-section round. Subacicular hooks (Figure 37c,j) brown, bidentate. Hooks first present from setiger 18-19, present in all setigers thereafter, always single (except for replacements). Shafts strongly curved; head very distinct; proximal teeth large, curved, directed laterally or basally. Distal teeth smaller, strongly curved and directed laterally. UNKNOWN MORPHOLOGICAL FEATURES.—Posterior termination of branchiae; pygidium and anal cirri. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—Branchiae continued to near posterior end. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 22, 34, 56, 58, 59. Unknown Characters: 1, 2, 36-38,40,42, 74, 78. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—37,1; 38,1. REMARKS.—Eunice denticulata belongs to group B-4 and is compared to similar species in Tables 33 and 39. Among the species in Table 39, it most closely resembles E.flavapunctata in that the inflated bases of median ventral cirri form thick, transverse welts in both species. Eunice denticulata has expanded, slightly hammer-headed aciculae; the aciculae are tapering in E. flavapunctata. Eunice depressa Schmarda, 1861 Eunice depressa Schmarda, 1861:127-128,11 figs. Marphysa depressa.—Grube, 1878a:101—Augener, 1924:409. REMARKS.—This species was referred to Marphysa by Grube (1878a: 101). Augener (1924:409) redefined the species. The original description clearly indicates that Schmarda had a species of Marphysa. 52. Eunice dilatata Grube, 1877 FIGURE 38a-f; TABLES 33,38 Eunice dilatata Grube, 1877:530-531.—Fauchald, 1986:248-249, figs. 29-34. MATERIAL EXAMINED.—Holotype, ZMB 896, Salavatti, Timor, coll. Exp. Gazelle. COMMENTS ON MATERIAL EXAMINED.—The prostomium had been laterally dissected, so the lower outline of the peristomium has been reconstructed in the illustration. DESCRIPTION.—Holotype incomplete, of unknown sex, with 92 anterior setigers; length 70 mm; maximal width 10 mm at setiger 85; length through setiger 10, 16 mm; width at setiger 10, 5 mm. Anterior end cylindrical, becoming strongly dorsoventrally flattened by setiger 30; segments becoming very short and crowded near posterior end. Prostomium (Figure 38b) distinctly shorter and narrower than peristomium, less than l /2 as deep as peristomium. Prostomial lobes frontally obliquely truncate, dorsally flattened; median sulcus deep. Eyes between bases of A-I and A-II, black. Antennae in a horseshoe; A-I and A-II separated by gap from A-III; A-III located well forward of other antennae; A-III half as thick as A-I and A-II. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles digitiform, without obvious articulations. A-I to posterior peristomial ring; A-II to end of setiger 1, and A-III to end of setiger 2. Peristomium about twice as long as prostomium, cylindrical. Separation between peristomial rings visible, but indistinct dorsally, possibly also ventrally, but specimen damaged; anterior ring 3 A of total peristomial length. Peristomial cirri short, digitiform, without articulations. Maxillary formula 1+1, 5+5, 8+0, 6+7, and 1+1; Mx II with unusually large and heavy teeth compared to other maxillae. Branchiae (Figure 38c) present, pectinate, distinctly longer than notopodial cirri, not reduced in mid-body region, flexible. Branchiae from setiger 19 to end of fragment. First 5 pairs single filaments; maximum 6 filaments; most branchiae with 5 filaments; this number of filaments continued to end of fragment. Branchial stems slender, longer than notopodial cirri. Filaments digitiform, longer than notopodial cirri, increasing in length posteriorly. Anterior neuropodial acicular lobes (Figure 38a) symmetrically rounded; median and posterior acicular lobes distally truncate; aciculae emerging at midline. Presetal lobes low, transverse folds. Anterior postsetal lobes free, rounded, about as high as acicular lobes, reduced to low folds from median setigers. Median and posterior parapodia on high ridges thus all parapodial structures, including aciculae, free of body wall, resembling large, flattened paddles with parapodial features carried at distal end. Anterior ventral cirri large, tapering from
