MATERIAL EXAMINED.—Challenger station 33, off Bermuda, 32° 21′ N, 64° 35′ W, 796 meters, coral mud, 4 April 1873—holotype Eulepis wyvillei (BMNH 1885: 12: 1: 105a).

Mayaguez Harbor, Puerto Rico: Fish Hawk station 6062, 46-55 meters, sand, mud, shells, 20 January 1899—holotype E. splendida (USNM 15916); Fish Hawk station 6065, 7-11 meters, 20 January 1899—paratype E. splendida (USNM 15917).

Grenada, Caribbean Sea, Blake station 247, 311 meters—1 specimen (MCZ 2235).

DESCRIPTION.—Length 18-37 mm, width 4-5 mm, including setae, segments 35-38. Elytra 12 pairs, becoming more elongate posteriorly, with lateral notch (Figure 4g-i); first pair elytra (missing on types of E. wyvillei and E. splendida; present on MCZ 2235) with margin entire except for a notch on inner anterior border; without papillae. Branchiae elongate, inflated, ciliated on underside; distal branchial cirrus oval, tapering distally (Figure 5b). Dorsal cirri, on segments 3 and 6, subulate (Figure 4e). Posterior lamellae, beginning on segment 28, subcordiform to lanceolate (Figure 4c).

Posterior half of prostomium covered by segment II, attached along midline; median antenna short, conical, inserted anterodorsally on prostomium; lateral antennae slightly longer, inserted more ventrally; ventral palps elongate-tapered, extending beyond tentacular cirri; eyes not visible; nuchal organs oval, lateral to prostomium (Figure 4b). Tentacular parapodia (I) with short subulate tentacular cirri, subequal in length or with ventral pair slightly longer than dorsal pair; 2 acicula; 2 tufts capillary setae (Figure 4a, b). Ventral buccal cirri segment II thicker than following ventral cirri (Figure 4d).

Biramous parapodia supported by dark reddish amber-colored acicula and neuropodial hammer-shaped distal plate (Figures 4d-f; 5a). Notopodial acicula with hooked tips. Notopodial capillary setae smooth and spinous, forming long, spreading bundles on posterior parts of notopodia; stout reddish amber-colored notopodial hooks, beginning on segment III, smooth, with tips finely tapered or flattened spoon-shaped (Figure 5c). Neuropodial acicula with conspicuous hammer-shaped plates; thin-walled inflated areas on dorso-anterior parts of neuropodial bases (Figures 5a). Neurosetae of several kinds: 1-2 upper pectinate setae (Figure 5d); limbate capillaries with tips elongate, curled (Figure 5e); lower non-limbate capillaries (Figures 5f); neurosetae of posterior region similar to anterior region (without some stouter upper neurosetae, as in some species of eulepethids). Ventral cirri of anterior few segments slender, tapered (Figure 4e, f); rest globular, with short slender tips (Figure 5a, b). Pygidium with single long anal cirrus on right side; cirrus finely papillate along one side (Figure 4c). Pharynx not extended.

DISTRIBUTION.—North Atlantic off Bermuda, Caribbean region. In 7 to 796 meters.
