NUMBER 523 287 articulations. Grube referred the species, incorrectly, to E. vittata. The latter lacks branchiae on the posterior half of the body. Grube suggested that E. rissoi might be the same as E. rubrocincta Ehlers; the branchial distribution certainly is closer to the latter than it is to E. vittata. However, Grube's suggestion is certainly not adequate to propose a synonymy. The information available is insufficient to characterize E. rissoi and it is here considered indeterminable. 168. Eunice rosaurae Monro, 1939 FIGURE 96i-p; TABLES 24,25.52,53 Eunice rosaurae Monro. 1939:351-352, fig. 282 a-f [in part]. MATERIAL EXAMINED.—Two syntypcs, ZK 1941.1.1.217- 221, off St. George, Grenada, 12°05'N, 61°49'W, 720-800 m, 27 Nov 1937, trawled, Rosaura Expedition, Atlantic, 1937-38, sta34. COMMENTS ON MATERIAL EXAMINED.—Two of the three original syntypes fit the species as described by Monro; the third syntype belongs to E. collini and is treated above. Of the two syntypes, one had been dissected and the jaws were separated; it agrees with the specimen described in detail by Monro and forms the base of the description given below. DESCRIPTION.—One syntype complete with 142 setigers; total length 152 mm; maximal width 4 mm; length through setiger 10, 18 mm. Other syntype nearly complete with 138 setigers; length 170 mm; maximal width 4 mm; length through setiger 10, 18 mm. Prostomium (Figure 96i) distinctly shorter and narrower than peristomium, as deep as ! /2 of peristomium. Prostomial lobes frontally obliquely truncate, dorsally somewhat flattened; median sulcus deep. Eyes between bases of A-I and A-II, black. Antennae in a horseshoe, evenly spaced, similar in thickness. Ccratophores ring-shaped in all antennae, without articulations. Ceratostyles medially inflated; inner half without articulations; outer half of ceratostyles increasingly articulated; outer articulations distinctly moniliform; maximum 13 articulations in A-III. A-I to posterior margin of peristomium; A-II to setiger 3; A-III to setiger 3, but slightly longer than A-II. Peristomium cylindrical. Separation between rings distinct dorsally only; anterior ring 3 /4 of total peristomial length. Peristomial cirri to front edge of posterior peristomial ring, medially inflated, without articulations. Maxillary formula 1+1, 6+6, 8+0, 5+5, and 1+1. Branchiae (Figure 96j) present, single filaments, distinctly shorter than notopodial cirri, not reduced in mid-body region. Branchiae from setiger 3 to setiger 48-55. Branchiae terminating well before posterior end, present on less than 55% of total number of setigers. First and last 10 branchiae small tubercles. All other branchiae single, slender filaments. Anterior neuropodial acicular lobes distally truncate with aciculae emerging near upper corner of lobes. Posterior acicular lobes distally triangularly rounded with both aciculae emerging centrally. Anterior and median pre- and postsetal lobes follow outline of acicular lobes closely. Posterior pre- and postsetal lobes low, transverse folds. First 5 ventral cirri basically digitiform, slightly tapering. Ventral cirri basally inflated from setiger 6 through branchial region. Inflated bases ovate; narrow tips digitiform. Posterior ventral cirri retaining short, inflated bases as sausage-shaped thickenings along ventral edge of parapodia; narrow tips digitiform. Prebranchial notopodial cirri slender, gently inflated basally; branchial notopodial cirri somewhat more inflated. Postbranchial notopodial cirri (Figure 96k) slender with distinct separation between cirrophores and cirrostyles. Limbate setae slender, marginally obscurely serrated. Pectinate setae (Figure 961,o) tapering, flaL One marginal tooth distinctly longer than other teeth; -10 teeth present. Shafts of compound falcigers (Figure 96m) distally tapering, marginally serrated. Appendages short, bidentate. Proximal teeth smaller than distal teeth, very short, tapering, curved laterally. Distal teeth gently curved, slender. Guards bluntly pointed, marginally serrated; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae mostly paired, single in anterior setigers, with black cores and clear sheaths, distally tapering, gently curved (Figure 96n). Subacicular hooks (Figure 96p) with black cores and clear sheaths, sometimes including all teeth; some hooks distally tridentate with 2 large distal teeth in tandem and small, nearly clear proximal teeth. In other hooks distal teeth fused, so hooks apparently bidentate. Bidentate hooks in full lateral view identical in appearance to tridentate ones, with both teeth pointing distally. Hooks first present from setiger 38 (32 in the other specimen), present in all setigers, always single (except for replacements). be- UNKNOWN MORPHOLOGICAL FEATURES.—Relationship tween Mx III and left Mx IV; pygidium and anal cirri. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 34, 39-42, 56, 60. Unknown Characters: 4, 6. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice rosaurae is listed with similar species in Tables 24 and 25. It resembles two additional species in Table 25 in having short branchiae consisting of single strap-like filaments. These two species, E. gravieri and E. nicidioformis, have exclusively bidentate subacicular hooks. Tridentate subacicular hooks with the teeth in tandem present in some neuropodia have not been found in any other species in group Bl. A total of four species are known to have the distal teeth in tandem in the genus; these are listed in Tables 52 and 53. Two of these have light yellow aciculae and subacicular hooks. The only other species with dark aciculae and subacicular hooks is E. cirrobranchiata. All aciculae are pointed in E. rosaurae: the aciculae are in part hammer-headed in E. cirrobranchiata.
