198 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY larger than distal teeth, directed laterally, distally upturned. Distal teeth nearly erect, triangular. UNKNOWN MORPHOLOGICAL FEATURES.—Pygidium anal cirri. and EXPECTED STATES OF SELECTED UNKNOWN FEATURES.— None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 22, 34, 56, 58, 59. Unknown Characters: 4,6,74,78. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice Uta is listed with similar species in Tables 33 and 38. An unusual feature of the species is the high number of setigers with single branchial filaments, both before and after the peak number is reached, and the fact that the branchiae terminate well before the posterior end of the body. Eunice longicirrata (Kinberg, 1865) Nicidion longicirrata Kinberg, 1865:564; 1910:43. pL 16: fig. 20. Eunice (Nicidion) cariboea.—Hartman, 1948:80 [not Eunice cariboea Gmbe, 1856]. MATERIAL EXAMINED.—Holotype, RM 415, Honolulu, Hawaii, Eugenie Expedition. COMMENTS ON MATERIAL EXAMINED.—Kinberg (1865:564) gave locality information as "Mare pacificum juxta urbem Honolulu insulae Oahu, inter corallia, summa aqua." The type lot includes a very poorly preserved anterior end and a median fragment. The anterior end has been ripped apart and the whole jaw apparatus is missing. DESCRIPTION.—A-111 distinctly longer than A-I and A-II. Separation between peristomial rings distinct dorsally, but probably not laterally; unknown for ventral side. Peristomial cirri to frontal margin of peristomium. Branchial distribution cannot be determined. Median fragment with long, digitiform single branchial filaments. Shape of parapodial structures indeterminable. Notopodial cirri short, slender in median fragment Limbate setae marginally serrated. Shafts of compound hooks strongly inflated. Appendages short; both teeth directed laterally. Hoods short, symmetrically rounded, marginally serrated. Aciculae brown, distally bent Subacicular hooks and pectinate setae absent in both fragments. REMARKS.—Hartman (1948:80) referred Nicidion longicirrata to Grube's species, Eunice cariboea, originally described from Caribbean. This synonymy is incorrect. In E. cariboea all antennae are similar in size and digitiform, in the type of E. longicirrata, A-III is distinctly longer than other antennae and all antennae tapering. The absence not only of subacicular hooks, but also of pectinate setae points to an affiliation with Palola rather than with Eunice, but the specimen is in such poor shape that it cannot be accurately assigned to genus. Eunice longicirrata Kinberg is here considered indeterminable. Eunice longicirrata Webster, 1884 Eunice longicirrata Webrter, 1884:318-319, pL 12: figi. 75-80. Eunice websteri Fauchald, 1969:12-14. fig. 6a-e. REMARKS.—Fauchald (1969:12) renamed this species, pointing out that the name applied by Webster had been preoccupied in combination E. longicirrata (Kinberg, 1865). The species is described below. 107. Eunice longicirris Grube, 1869 Eunice longicirris Grube, 1869:492. FIGURE 66a-f. MATERIAL EXAMINED.—Holotype, ZMB 499, Suez, coll. Ehrenberg. COMMENTS ON MATERIAL EXAMINED.—The type lot consists of one anterior end, two posterior ends, and several long sections of median setigers. The features of all pieces are closely similar and are here assumed to belong to the same species', however, it is unclear how the pieces match, so measurements were taken on the anterior fragment only. DESCRIPTION.—Anterior fragment of unknown sex, with 30 setigers; length 43 mm; maximal width 5 mm; length through setiger 10,16 mm. Prostomium (Figure 66d) distinctly shorter and narrower than peristomium, as deep as x fi of peristomium. Prostomial lobes frontally rounded, dorsally inflated; median sulcus shallow. Eyes posterior to bases of A-I; faded. Antennae in horseshoe; A-I and A-II separated from A-III by gap; A-III slimmer than A-I and A-II. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles tapering, with up to 14 long, articulations in A-III; basal articulations cylindrical, distal ones drop-shaped. A-I to posterior peristomial ring; all other antennae incomplete; A-II to setiger 1; A-III to setiger 3. Peristomium cylindrical. Separation between rings distinct dorsally and ventrally; anterior ring ~ 3 A of total peristomial length. Peristomial cirri outreaching prostomium, very slender, tapering, with 8 articulations. Maxillary formula 1+1,7+7,7+0, 8+10,1+1. Mx III part of distal arc with left Mx IV. Left Mx IV with very small teeth. Mx VI absent. Branchiae (Figure 66a) present, pectinate, distinctly shorter than notopodial cirri, erect Branchiae from setiger 3 to end; all branchiae pectinate except last 10-15 pairs. Maximum 7 filaments at about setiger 15. Stems slender, cylindrical, shorter than filaments. Filaments slender, digitiform, shorter than notopodial cirri. Anterior neuropodial acicular lobes distally truncate, becoming triangular in posterior setigers; aciculae emerging above midline. Pre- and postsetal lobes low, transverse folds. Anterior ventral cirri thick, tapering, becoming basally distinctly inflated from about setiger 5. Inflated bases ovate; narrow tips tapering. Posterior ventral cirri tapering without inflated bases.
