?Eunice afra.—Hartman 1956:282 [in part, not Peters, 1854].

COMMENTS ON MATERIAL EXAMINED.—The type material has been lost. The description by Treadwell, although somewhat incomplete, is sufficient to characterize the species.

DESCRIPTION.—Complete specimen with 95 setigers; total length 40 mm; width about 1 mm.

No antennae outreaching peristomium, without articulations. Peristomial cirri short, without articulations.

Maxillary formula 1+1, 4+4, 5+0, 3+6, and 1+1; Mx III illustrated as short; part of distal arc with left Mx IV.

Branchiae present, not reduced in mid-body region. Branchiae from setiger 14 to setiger 70. Branchiae terminating well before posterior end, present on more than 65% of total number of setigers. Small specimens with single, strap-like filaments only; larger specimens with up to 3 filaments.

Ventral cirri basally inflated from about setiger 10; distribution of inflated bases otherwise unknown. Notopodial cirri short, tapering, supported by internal aciculae in all setigers. Notopodial cirri without articulations.

Limbate setae marginally smooth. Pectinate setae tapering, furled. Both marginal teeth longer than other teeth; ~20 teeth present. Shafts of compound falcigers inflated, marginally serrated. Appendages with nearly parallel sides, bidentate. Proximal teeth larger than distal teeth, triangular, directed slightly basally. Distal teeth distinctly curved. Guards symmetrically bluntly pointed, marginally serrated; mucros absent. Pseudocompound falcigers and compound spinigers absent. Aciculae tapering, distally slightly bent. Aciculae and subacicular hooks with light- to dark-brown cores and clear sheaths. Subacicular hooks bidentate. Both teeth directed distally; proximal teeth somewhat larger than distal teeth.

UNKNOWN MORPHOLOGICAL FEATURES.—Many features from all parts of the body.

EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEATURES.—None.
