Eunice equibranchiata McIntosh, 1885:291–292. pl. 39; fig. 11, pl. 20A: figs. 23, 24.
MATERIAL EXAMINED.—Holotype, BM(NH) ZK. 1885.12.1.202. Brazil, 9°5′–9°10′S, 34°49′–34°53′W, 640, 219, 59, and 732 m, mud, 10 Sep 1873, Challenger sta 202.
DESCRIPTION.—Holotype and only known specimen is a middle piece of about 300 segments; length 250 mm.
Prostomium, peristomium and jaws unknown.
Branchiae long, slender; up to 3 filaments of similar lengths; all segments present branchiated.
Neuropodial acicular lobes (Figure 42d) conical. Pre- and postsetal lobes follow outline of acicular lobes closely. Ventral cirri digitiform with distinct, but low basal inflations on adjoining body wall. Notopodial cirri tapering, slender, without articulations, at least twice as long as ventral cirri.
Most setae broken. Shafts of compound hooks distally inflated. Appendages (Figure 42a) short. Both teeth very well developed, directed laterally. Guards symmetrically rounded, marginally serrated. Aciculae (Figure 42b) single, with dark cores and clear sheaths, distally asymmetrically hammer-headed. Subacicular hooks (Figure 42c) with dark cores and clear, translucent heads. Hooks strongly curved, with large heads. Both teeth curved, directed laterally.
