. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. FIGURE 2. Adult specimen of Aglaophamus ncotcnus, new species: A, right jaw lying on its anterior surface, B. postacicular spinous setae, C, preacicular barred capillary setae; D, aciculum. six to eight per fascicle and are replaced by smooth capillary setae at about setiger 20. Spinous setae are replaced by smooth capillaries over last few posterior setigers. Ornamentation of barred capillaries is on the outer one third of shaft (Fig. 2C). Spinous setae have blade-like edges subdistally, bearing fine spinets (). Pharyngeal region occupies setigers two through eight, is swollen due to re- tracted proboscis, and provides slightly upward-curving appearance to worm. Proboscis cylindrical, with distal row of 16 or 18 papillae with 14 to 16 longi- tudinal rows of fine subterminal papillae behind distal papillae; five to six fine, pointed papillae occupy each subterminal row. A single, long, mid-dorsal sub- terminal papilla is present. Proximal surface of proboscis is free of ornamentation (Fig. IB). Jaws very small, about 125 /xm on longest axis, color golden brown, base roughly triangular; an inner supportive ridge appears to be present, but jaw detail is difficult to determine due to small size (Fig. 2A). Body coloration in living worms varies from creamy white to pink or light orange; females more pink or orange than males. Dorsally, prostomium is yellow ; dark red, sometimes almost black pigment granules are scattered over its surface. A dark red pigment spot is located on the distal and slightly ventral end of the prostomium. Prostomial pigmentation can vary somewhat between individuals. Paired, dark red, pigment spots, located dorsally on the pygidium may be "pygidial eyespots". The distal end of the pygidium is yellow. Fading of pigmentation occurs to varying degrees with Please note that these images are extracted from scanned page images that may have been digita
