218 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY FIGURE 72.—Eunice mexicana (lectotype, AHF Poly 1539): a, anterior end, lateral view; b, compound falciger, parapodium 3; c, pectinate seta, parapodium 3; d, parapodium 3, anterior view; e, parapodium 15, anterior view; f, pectinate seta, parapodium 15; g, compound falciger, parapodium 15; h, aciculae, parapodium 15; i, pectinate seta, parapodium 48; j, compound falciger, parapodium 48; k, aciculae and subacicular hooks, parapodium 48. (Scale bars in mm.)

Hooks first present from setiger 32, present in all setigers thereafter, usually 3 in a vertical row in posterior setigers. Hooks gently curved; necks and heads distinct. Proximal teeth larger than distal teeth, directed laterally. Distal teeth nearly erect, slender. UNKNOWN MORPHOLOGICAL FEATURES.—Pygidium anal cirri. EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA- TURES.—None. CHARACTERS USED IN PREPARATION OF KEY NOT SCORED.—Inappropriate Characters: 56, 58, 59. Unknown Characters: None. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Through a lapsus, type locality and type specimens were not designated when the species was first described; I take the opportunity to rectify the error at this time by designating lecto- and paralectotypes for the species. As indicated above, the species is separated from other species in the group by the same kinds of characters used to separate other species, thus subspecific status originally designated is unjustified. Eunice mexicana is listed with similar species in Tables 19 and 20. It is very similar to E. pennata in distributional features, but can be separated from it by having 18 rather than 12 branchial filaments and usually three subacicular hooks in a vertical row rather than having maximally paired subacicular hooks as in E. pennata. Eunice elegans (see Table 24) also resembles E. mexicana and closely, but can be separated as suggested in the discussion of the former. 122. Eunice microprion Marenzeller, 1879 FIGURE 73a-k; TABLES 27,29 Eunice microprion Marenzeller, 1879:135-136, pi 5: fig. 1, 1A-1D.—Imajima and Hartman, 1964:252. MATERIAL EXAMINED.—ZMW 1062, Jaqashima, Japan, don. DOderlein, 1 specimen; ZMW 1064, Eno Shima, Japan, don. Doderlein, 1 specimen. COMMENTS ON MATERIAL EXAMINED.—The specimens listed above are not the types, but specimens identified by v. Marenzeller from collections taken at or near the type area. DESCRIPTION.—Specimen from ZMW 1062 complete with 127 setigers; total length 82 mm; maximal width 5 mm; length through setiger 10, 10 mm. Other specimen incomplete with 124 setigers; length 85 mm; maximal length 5 mm; length through setiger 10,12 mm. Both specimens cylindrical, gently tapering. Anal cirri as long as last 10 setigers together. Prostomium (Figure 73a) distinctly shorter and narrower than peristomium, less than x li as deep as peristomium. Prostomial lobes frontally obliquely truncate, dorsally excavate with a thickened rim; median sulcus deep. Eyes near bases of A-II, dark. Antennae in a horseshoe; with A-III isolated by a gap, similar in thickness. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles tapering very slowly towards tips, with up to 10 poorly marked, cylindrical
