278 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY 2 1 .02 .1 a e b, c FIGURE 93.—Eunice pulvinopalpata (holotype, USNM 74304): a, anterior end, lateral view; b, compound fakiger, parapodium 105; c, pectinate seta, parapodium 105; d, subacicular hook, parapodium 105; e, parapodium 105, anterior view. (Scale bars in mm.)
NUMBER 523 279 18+0, 12+12, and 1+1. Mx III behind left Mx II. Both Mx IV with same number of teeth. All teeth very small and even in size. Branchiae (Figure 93e) present, pectinate, distinctly shorter than notopodial cirri, not reduced in mid-body region, flexible. Branchiae from setiger 3 to end of body. Branchiae present to near posterior end, present on more than 65% of total number of setigers. First pair single filaments, all other branchiae with at least 4 filaments; maximally 25 filaments from setiger 15 to setiger 275; thereafter number slowly reduced; 15 filaments present in last setigers. Branchial stem thick, folded over in most parapodia. Filaments filiform. Neuropodial acicular lobes asymmetrically rounded with aciculae emerging on dorsal side. All presetal lobes obliquely truncate. All postsetal lobes low, transverse folds. First 5 or 6 ventral cirri thick, digiliform. Ventral cirri basally inflated by setigers 6-7; inflated bases retained through about setiger 250. Inflated bases nearly spherical; narrow tips tapering. Far posterior ventral cirri tapering. Notopodial cirri very long, especially in anterior part of body. Where best developed, at about setiger 100, longer than width of body, slender, tapering, without articulations. Limbate setae marginally smooth. Pectinate setae (Figure 93c) tapering, flat. One marginal tooth very much longer than other teeth; 8 teeth present. Shafts of compound falcigers (Figure 93b) slightly inflated, marginally smooth. Appendages tapering, bidentate. Both teeth of same size, slender, tapering. Proximal teeth directed distally; distal teeth gently curved. Guards asymmetrically bluntly pointed; mucros absent. Pseudocompound falcigers and compound spinigers absent. Most aciculae in triplets, dark brown to black, with tapering slender tips, straight; cross-section round. Separation between cores and sheaths indistinct in both aciculae and subacicular hooks. Subacicular hooks (Figure 93d) dark brown to black, bidentate. Hooks first present from setiger 68 in holotype (from setigers 62-72 in paratypes), present in all setigers thereafter, always single (except for replacements). Hooks slender, tapering to a small head. Proximal teeth slightly larger than distal teeth; both teeth directed distally. UNKNOWN MORPHOLOGICAL FEATURES.—Pygidium anal cirri. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 56, 58, 59. Unknown Characters: 1, 2,4, 6, 13, 14, 36. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice pulvinopalpata is a member of group B-2; however, it also resembles some of the deep-water members of group A-1 and should be compared to these species as well (Tables 19-21). It is branchiated to near the posterior end, in contrast to most other deep-water species. It is listed with similar species in group B-2 in Tables 27 and 31. The only and other species in Table 31 with more than 20 branchial filaments is E. franklini. The branchial filaments in the latter are very short and stubby; those in E. pulvinopalpata are slender, digitiform and certainly not unusually short. Eunice punctata (Risso, 1826) Ltodice punclata Risso, 1826:421-422. Eunice punctata.—Quatrefages, 1866:331. REMARKS.—This species, of which no authoritative material exists, was considered either indeterminable or doubtfully as a member of Marphysafallax by Fauvel (1923:451). The species described by Heider (1925) under this name cannot be a Marphysa because it has peristomial cirri; it is here considered as E. harassii. Eunice punctata (Risso) is indeterminable. Eunice punclata Peters, 1854:611. Eunice punctata Peters, 1854 REMARKS.—The specific name is preoccupied in the combination E. punctata (Risso, 1826). Peters' species is redescribed above as E. petersi. Eunice punctata Grube, 1856 Eunice punctata Grube, 1856:59-60. Eunice binominata Quatrefages, 1866:327. REMARKS.—Quatrefages (1866:327) pointed out that Grube's specific name was pre-occupied by Risso (1826); Quatrefages apparently had overlooked Peters' use of the name, issued two years before Grube *s paper, so the name was in fact doubly pre-occupied by the time Quatrefages reviewed the matter. Grube's species is here discussed as E. binominata. 164. Eunice purpurea Grube, 1866 FIGURE 94; TABLES 27,30 Eunice purpurea Grube, 1866b:68. Eunice vlolacea.—Grube, 1861:60-61 [not Eunice violacea Grube, 1856]. MATERIAL EXAMINED.—Two syntypes, ZMB F 2012, Portor6, Lesina, Adriatic Sea, coll. Grube. COMMENTS ON MATERIAL EXAMINED.—The description is based wholly on the large specimen; some notes on the small specimen, which is a juvenile, have been appended. The peristomium of the large specimen has been ventrally dissected and the jaw apparatus torn partially loose; the illustration shows the condition with the jaws tucked back into position, but is in part a reconstruction where tissue had been removed. DESCRIPTION.—Large syntype complete with 106 setigers; total length 53 mm; maximal width 4 mm; length through setiger 10, 9.5 mm. Other syntype with 40 setigers; length 7 mm long. Prostomium (Figure 94a) distinctly shorter and narrower
