Unknown Characters: 4, 6,42, 65-68. ASSUMED STATES FOR PURPOSE OF PREPARING KEY.— None. REMARKS.—Eunice marovoi was described with bluntly rounded guards to compound hooks and with branchiae extended to setigers 23-25; as indicated above, guards are mucronate and branchiae are not found on any segment later than 22 in the specimens examined. The dentition of the jaws is remarkable and may represent a juvenile dentition. The shape of the subacicular hooks also resembles the condition found in juvenile specimens. None of the specimens are sexually mature. Eunice marovoi is listed with similar species in Tables 41 and 45. It is the only species known to combined nonarticulated ceratostyles with multiple subacicular hooks. 118. Eunice martensi Grube, 1878 Eunice martensi Grube, 1878a:102.

COMMENTS ON MATERIAL EXAMINED.—The specimen is very poorly preserved and no meaningful illustrations of soft parts are possible. DESCRIPTION.—Holotype complete with 168 setigers; total length 220 mm; maximal width 6 mm; length through setiger 10, 14 mm. Body apparently cylindrical, slowly tapering posteriorly. Prostomium distinctly shorter than peristomium. Median sulcus very shallow. Eyes between bases of A-I and A-II. Ceratophores ring-shaped in all antennae, without articulations. Ceratostyles digitiform, with up to 10 cylindrical articulations in A-II. Only right A-I and A-II complete. A-I to anterior peristomial ring; A-II to setiger 1. Peristomium cylindrical. Separation between rings distinct dorsally and ventrally; anterior ring 3 /4 of total peristomial length. Peristomial cirri to posterior end of prostomium, slender and digitiform, with 5 articulations. Maxillary formula 1+1, 6+6, 10+0, 9+10, and 1+1. Mx III long, located behind left Mx II. Mx VI absent. Branchiae present, pectinate, distinctly longer than notopodial cirri, not reduced in mid-body region, erect. Branchiae from setiger 6 to setiger 163. Branchiae present to near posterior end, present on more than 65% of total number of setigers. All branchiae pectinate with up to 16 filaments at setigers 15-20. Branchial stems very thick, tapering, erect. Filaments short, digitiform. Number of filaments decreasing posteriorly; 6 filaments in setiger 150. No increase in number of filaments, length of filaments, or of branchial stem towards posterior end. All neuropodial acicular lobes apparently truncate or rounded; aciculae emerging at midline. All pre- and postsetal lobes low, transverse folds. Anterior ventral cirri tapering, becoming moderately basally inflated in some median setigers. Inflated bases ovate; narrow tips tapering. Posterior ventral cirri without basal inflation, tapering. All notopodial cirri basally
