Pliyllodoce duplex McIntosh, 1885, p. 1G7, pi. 27, fig. 8; pi. 32, fig. 9; pi. 15o, fig. 1. Collected at station D5113, Sombrero Island, Balayan Bay, 159 fathoms, dark green mud bottom. Genus MYSTA Malmgren. MYSTA MACULATA, new species. A single specimen, with a length «of approximately 60 mm. Width of head between tentacles, mm.; width at somite 20, mm. There were about 146 somites present, the posterior end having been lost. Anteriorly the propor- tion of length of somite to breadth is as 1 to 8, and the dorsal cirri are inconspicuous. Beginning with approximately the fortieth somite there is a gradual change in the proportion of length to breadth, and toward the posterior end this proportion is about as 1 to 2. An- teriorly the dorsal cirri are very inconspicuous, and while they overlap one another to a certain extent they cover no part of the somite surface. Posteriorly these cirri become much more promi- nent, but still do not overlap the body. Each dorsal cirrus is marked with a median dark spot, rather faint anteriorly but very prominent posteriorly. The gen- eral body color (in alcohol) is a very light brown, marked on the dorsal surface with dark spots, which in the anterior somites show a tendency to arrange themselves in a transverse row near the anterior border of the somite. Ventrally the body has a broad median dark band, spotted with white. The prostomium (fig. 1) is, roughly speaking, lens-shaped, with the long diameter transverse, this long diameter being about one- fourth longer than the antero-posterior one. About one-quarter of.
