194 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY 64d) paired, yellow, most tapering distally to nearly straight, blunt tips, some very abruptly tapering with short, nearly nipple-shaped tips; cross-sections round. Separation between core and sheath indistinct in both aciculae and subacicular hooks. Subacicular hooks (Figure 64f) yellow, bidentate. Hooks first present from setiger 51, present in all setigers thereafter, always single (except for replacements). Proximal teeth much larger than distal teeth, very thick, short, triangular, directed laterally. Distal teeth short, blunt, erect. UNKNOWN MORPHOLOGICAL FEATURES.—Jaw structure; pygidium and anal cirri. EXPECTED STATES OF SELECTED UNKNOWN FEATURES.— None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 22, 56, 58, 59. Unknown Characters: 1, 2,4, 6, 13, 14, 36-40. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—37,1; 38,1. REMARKS.—Eunice leptocirris has not been reported since it was originally described by Grubc (1870b:55); the original description was so brief that the species has been considered indeterminable by most authors. The species belong to group A-2 and is listed with similar species in Tables 22 and 23. The only other species listed in Table 23 without articulated ceratostyles is E. schizobranchia. Among other differences, the latter has dark aciculae and yellow subacicular hooks; E. leptocirris has both the aciculae and subacicular hooks light-colored. Eunice leucodon Ehlers, 1901:261. Eunice leucodon Ehlers, 1901 REMARKS.—Examination of the type material demonstrated that this species has the jaw structure and setal complement of the genus Palola. It is included in a treatment of that genus currently in preparation. Eunice leuconuchalis Benham, 1900 Eunice leuconuchalis Benham, 1900:21-22.—Fauchald, 1986:252-253. Eunice australis.—Ehlers, 1907:12.—Fauchald, 1986:244-245, figs. 9-14. REMARKS.—Justification for considering this species a synonym of E. australis was reviewed by Fauchald (1986). 103. Eunice leucosticta Grube, 1878 Eunice leucosiicia Grube, 1878a:103. FIGURE 64g-i; TABLES 33,37 MATERIAL EXAMINED.—Slide of parapodium from holotype, Zool. Mus. Berlin, F-2044, East Africa, coll. v.d. Decken. DESCRIPTION.—Slide of a posterior parapodium, presumably near segment 120, without branchiae, but apparently not a segment immediately in front of the pygidium. Species described by Grube (1878a: 103) with 131 segments; total length 130 mm. Color dark red, densely studded with white spots. Three median antennae of same length, reaching segment 4 (including peristomium). Maxillary formula (rewritten from Grube) 1+1, 5+5, 10+0, 4+6, and 1+1. Branchiae from setiger 14 and 15 (presumably on either side of body) and continued to setiger 113, terminating well before end of specimen. Where best developed with 4 filaments, but 3 filaments by far most common number. Filaments short, no longer than short notopodial cirri. Neuropodia (Figure 64g) distally evenly rounded; aciculae emerging above midline. Pre- and postsctal lobes low folds. Posterior ventral cirri large, distally tapering, basally moderately inflated. Notopodial cirri short, digiliform in parapodium examined. Parapodium with a thick bundle of limbatc setae, a number of compound falcigcrs, and a few pectinate setae. Shafts of compound falcigcrs (Figure 64h) inflated, marginally smooth. Appendages short triangular, bidcnlatc. Tcelh similar in size. Proximal teeth tapering, curved, directed laterally. Distal teeth tapering, nearly erect. Guards symmetrically rounded; mucros absent. Pscudocompound falcigcrs and compound spinigers absent. Aciculae single, with dark brown cores and clear sheaths, tapering to straight lips; cross-sections round. Subacicular hooks (Figure 64i) with dark brown cores and clear sheaths. Hooks distally abruptly tapered. Proximal teeth larger than distal tcelh, tapering, directed laterally. Distal teeth abruptly tapering, directed obliquely distally. UNKNOWN MORPHOLOGICAL FEATURES.—All features associated with anterior and median parts of the body. EXPECTED STATES OF SELECTED UNKNOWN FEATURES.— None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: None known. Unknown Characters: 3-22, 24-29, 31-34, 38-40, 42, 45, 46, 48,49, 51-56, 60-62, 65-68, 80-82. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice leucosiicia was considered a synonym of E. afra by Hartman (1959). Eunice leucosticta appears to differ from E. afra in that the antennae are much longer than in that species and in that the two teeth on the subacicular hooks are directed laterally rather than distally as in E. afra. It is listed with similar species in Tables 33 and 37. It is too poorly known to be included in the key or to be discussed in detail in relation to similar species listed in Table 37. 104.
