88 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY 31. Eunice borneensis Grube, 1878 FIGURE 24; TABLES 27, 31 Eunice (Eriphyle) borneensis Grube, 1878a: 102. MATERIAL EXAMINED.—Three syntypes, ZMB F2033, North Borneo. COMMENTS ON MATERIAL EXAMINED.—All three syntypes are complete, one is in two pieces; they vary from 103 to 129 setigers and from 40 to 64 mm in length. The syntype described is the largest of the complete syntypes. DESCRIPTION.—Syntype with 120 setigers; total length 42 mm; maximum width 6 mm at about setiger 50. Length through setiger 10,7 mm; width at setiger 10,4.5 mm. Anterior body up to about setiger 30 cylindrical, becoming dorsoventrally flattened, strongly flattened near posterior end. Prostomium (Figure 24a) distinctly shorter than and narrower than peristomium, less than x li as deep as peristomium. Prostomial lobes frontally truncate, dorsally flattened; median sulcus deep. Eyes not observed. Antennae in a shallow horseshoe, evenly spaced, similar in thickness. Ceratophorcs ring-shaped in all antennae, without articulations. Ceratostyles slender and tapering; maximum 6 cylindrical articulations in A-II and A-111. A-I to middle of peristomium; A-II and A-111 to setiger 2. Peristomium massive and muscular; cylindrical. Separation between rings distinct dorsally and ventrally, indistinct only in narrow section laterally; anterior ring 6 /i of total peristomial length. Lower lip scalloped. Peristomial cirri to middle of anterior peristomial ring, slender and tapering, with 3 indistinct, cylindrical articulations (not shown in illustration). Maxillary formula 1+1, 4+4, 7+0, 5+11, and 1+1. Teeth of Mx II very large and coarse compared to other teeth. Branchiae (Figure 24b) present, pectinate, distinctly longer than notopodial cirri, not reduced in mid-body region, flexible. Branchiae from setiger 6 to setiger 120. Branchiae present to near posterior end, present on more than 65% of total number of setigers. First branchia with 3 filaments; maximal number of filaments 9 by setiger 15; last 10 setigers with single filaments. Branchial stem as thick as filaments, short, flexible, tapering. Filaments digitiform, longer than notopodial cirri. Anterior acicular lobes (Figure 24c) broadly, asymmetrically truncate with aciculae emerging above midline. Median and posterior neuropodial acicular lobes narrowly, asymmetrically rounded with aciculae emerging above midline. All presetal lobes low truncate folds. Anterior postsetal lobes free, truncate, longer than acicular lobe, becoming rounded in posterior setigers, but remaining longer than acicular lobes in all setigers. Four first ventral cirri thick, tapering. Ventral cirri basally inflated from about setiger 5. Inflated bases thick, transverse welts in all remaining setigers; narrow tips of ventral cirri small, nearly button-shaped. All notopodial cirri basally inflated with distinct rounded basal tubercular protuberance, without articulations. Limbate setae longer than other setae, slender, nearly straight, limbations narrow, marginally smooth. Pectinate setae (Figure 24g) short; shafts slender, cylindrical; blades flaring, fiat. One marginal tooth longer than other teeth; total of -15 teeth. Shafts of compound falcigcrs (Figure 24e) distally inflated, marginally smooth, with distinct distal beak. Appendages short, thick, barely tapering; heads large, bidentate. Proximal teeth tapering, directed laterally; distal teeth about as long as proximal teeth, but thicker, tapering, directed laterally. Guards asymmetrically bluntly pointed, marginally smooth, without mucros. Pscudocompound falcigcrs and compound spinigers absent. Aciculae paired anteriorly; 3 aciculae from about setiger 50, black, tapering, with narrowly blunt tips (Figure 24d), gently curved or straight; cross-section round. Subacicular hooks black (Figure 241), bidentate. Hooks first present from sctigcr 30-35, present in all setigers thereafter, single in most setigers, up to 3 in a few sctigcrs. Both teeth directed distally; proximal teeth slightly larger than distal teeth. UKNOWN MORPHOLOGICAL FEATURES.—Relation between Mx III and left Mx IV; pygidium and anal cirri. EXPECTED STATE OF UNKNOWN MORPHOLOGICAL FEA- TURES.—Mx III short, located in front of left Mx IV; forming part of distal arc. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 56, 60. Unknown Characters: 13,14,74,78. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice borneensis is listed with similar species in Tables 27 and 31. It appears to differ from other species listed in Table 31 especially in the presence of well-developed postsetal lobes, in the shape of the notopodial cirri, and in having the ventral cirri basally inflated to the posterior end. 32. Eunice bottae Quatrefages, 1866 FIGURE 25; TABLES 46,47 Eunice bottae Quatrefages, 1866:320.—Grube, 1870a:292. MATERIAL EXAMINED.—Holotype, MNHN, Paris, A.1(R.)- 1868-no. 55b, Red Sea, coll. Botta. DESCRIPTION.—Holotype incomplete with 60 setigers; length 28 mm; maximum width 2 mm at about setiger 40. Length through setiger 10,7 mm; width at setiger 10,1.75 mm. Body slender, cylindrical, becoming somewhat dorsally flattened towards posterior end. Prostomium (Figure 25a) distinctly shorter and narrower than peristomium, as deep as '/2 of the peristomium. Prostomial lobes irregularly rounded, dorsally flattened; median sulcus shallow; frontal groove marking off palpal region present. Eyes not seen. All antennae incomplete, except left A-I, in a shallow horseshoe, evenly spaced, similar in thickness. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles digitiform with maximum 15 moniliform articulations in A-I 11.
