308 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 56, 60. Unknown Characters: 4,6. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice sonorae belongs to the small group of species with dark, simple spine-like subacicular hooks and was compared to other species in group D4 by Fauchald (1970). It is listed with similar species in Tables 33,35, 50, and 51. It has multiple aciculae in anterior setigers and subacicular hooks first present from setiger 54; other species in Table 35 have single aciculae and the subacicular hooks are present much farther forward; in addition, the subacicular hooks are simple and spine-like in E. sonorae and are bidentate in the other species in this table. Eunice splendida Grube, 1856:58. Eunice splendida Grube, 1856 REMARKS.—No material is available of this species. The original description indicates that A-III should reach sctigcr 5 and have 26 moniliform articulations. The peristomial cirri have cylindrical articulations and reach the prostomium. The notopodial cirri lack articulations. Branchiae from setiger 5 to posterior end of the complete specimen; maximum 15 filaments; number of filaments decrease posteriorly. The specimen, which was collected at Valparaiso, Chile, resembles E. lucei according to Grube. The features mentioned are consistent with species in group C-2, but without information about setal structures the species cannot be assigned to a group. The information is inadequate to characterize the species and it is here considered indeterminable. 182. Eunice spongicola (Treadwell, 1921) FIGURE 105a-f; TABLES 33,39 Leodice spongicola Treadwell, 1921:25-27, figs. 53a-j. Eunice filamentosa.—Hartman, 1956:283 [in part, not Eunice filamentosa Grube, 1856]. MATERIAL EXAMINED.—Holotype, AMNH 1383, Montego Bay, Jamaica, Jul 1921. DESCRIPTION.—Holotype complete with 152 setigers; total length 68 mm; maximal width 1.75 mm at setiger 10; length through setiger 10, 6.0 mm. Body tapering evenly towards posterior end from widest point at about setiger 10. Prostomium (Figure 105a) distinctly shorter and narrower than peristomium, less than l /2 as deep as peristomium. Prostomial lobes frontally truncate, dorsoventrally flattened; median sulcus deep. Eyes behind bases of A-I, black. Antennae in a horseshoe, evenly spaced, similar in thickness. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles tapering, without articulations. All antennae outreaching tip of prostomium, none outrcaching peristomium. Peristomium nearly twice as long as prostomium, nearly twice as wide, cylindrical. Separation between rings distinct only ventrally; anterior ring 5 /6 of total peristomial length. Peristomial cirri to posterior edge of anterior peristomial ring, digitiform, without articulations. Jaws half everted. Maxillary formula 1+1, +, 7+0,3+5, and 1+1; dentition of Mx II not dcterminable without destroying specimen. Branchiae (Figure 105b) present, palmate, distinctly longer than notopodial cirri, not reduced in mid-body region. Branchiae from setiger 24 to setiger 150. Branchiae present to near posterior end, present on more than 65% of tolal number of setigers. First 5 branchiae with single filaments; maximum filaments 3 reached at midbody and maintained to near posterior end. Branchial stems very short, tapering. AH filaments very long, digiliform, longer than notopodial cirri in most setigers. Anterior ncuropodial acicular lobes distally truncate; posterior acicular lobes conical; aciculae emerging at midlinc. All prcsctal lobes low, transverse folds. Anterior postscial lobes distinct free lobes, about as high as acicular lobes; posterior postsetal lobes low, transverse folds. First 3 ventral cirri digitiform. Ventral cirri basally inflated between sciigcrs 4 and 50. Inflated bases large, ovate; narrow tips digitiform. Inflated bases rapidly reduced from setiger 50; posterior ventral cirri digitiform. Anterior notopodial cirri digitiform, about twice as long as ventral cirri, increasing in length posteriorly, nearly as long as branchial filaments in last setigers. Notopodial cirri without articulations. Limbate setae long, slender, marginally finely dentate. Pectinate setae (Figure 105c) flat, widely flaring. Both marginal teeth slightly longer than other teeth; -15 teeth present. Shafts of compound falcigers (Figure 105e) distally inflated, marginally serrated, without distinct beak. Appendages with distinct heads, slightly tapering, bidentate. Proximal and distal teeth similar in size. Proximal teeth tapering, directed slightly basally. Distal teeth strongly tapered, directed laterally. Guards symmetrically rounded, marginally smooth; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae (Figure 1050 single, amber-colored, darker near base than at tip, darker in posterior than in anterior setigers, distally expanded dorsoventrally into hammer-headed structures; shafts straight; cross-sections round. Subacicular hooks (Figure 105d) amber colored, darker near base than at tip, darker in posterior than in anterior setigers, bidentate. Hooks first present from setiger 26, present in all setigers thereafter, always single (except for replacements). Hooks with narrow necks; large heads. Proximal teeth larger than distal teeth, parrot-beaked, directed basally. Distal teeth nearly digitiform, distally blunt.
