Macellicephala (Macellicephala) remigata.—Hartmann-Schröder, 1974:76, 80. 84.

MATERIAL EXAMINED.—Southern California, off Santa Catalina Island, 611–1097 m, gray sand and rocks, Albatross sta. 4407, 9 April 1904, holotype (USNM 17220).

DESCRIPTION.—Length of holotype 15 mm, width including parapodia 7 mm, segments 18 (not incomplete, as indicated by Moore, 1910). Dorsal tubercles on cirrigerous segments large, bulbous (Figure 5c; Moore, 1910, pl. 31: fig. 48). Narrower anterior lobes of prostomium with minute frontal filaments (Figure 5a; overlooked by Moore, 1910; observed by Hartman, 1938). Median antenna with style missing. Palps rather short and tapered. Remaining left dorsal tentacular cirrus longer than palps. Small trilobed facial tubercle medial to bases of palps.

Parapodia typical (Figure 5a–c). Notosetae relatively few in number (3–6; mostly missing), slightly stouter than neurosetute, pale yellow, with blunt tips; shorter ones appearing smooth; longer ones with distinct spinous rows (Figure 5d Moore, 1910, pl. 31: fig. 49). Neurosetae delicate, flattened, appearing smooth or with faint serrations along margins, with pointed tips (Figure 5e; Moore, 1910, pl. 31: figs. 50, 51). Styles of dorsal cirri missing (Figure 5c; Moore, 1910, pl. 31: fig. 48; Moore evidently mistook dorsal tubercles for dorsal cirrophores).

Reduced parapodia of segment 18, lateral to pygidium, consisting of notopodia and dorsal cirrophores only. Nephridial papillae larger on segments 9, 10 and 11. Body smooth, not papillate.

DISTRIBUTION.—Northeastern Pacific (off southern California), in 611 to 1097 meters.
