Some species new to the area or new to science are treated here. FAMILY PHYLLODOCIDAE Eteonides coineaui dif ficilis, new subspecies Several anterior and posterior fragments, with up to 65 setigers 4.6 mm long were dredged in July 1961 at about 20 m south of Cattle Point, San Juan Island (appr. 48° 25.0' N; 122° 59.0' W) from coarse, not too clean sand. Other specimens were dredged in August 1962 between Reid Rock and Turn Island, near San Juan Island (appr. 48° 32.5' N; 122° 58.5' W), at about 100 m from a coarse, fairly clean sediment mostly made up of broken shells. Description: The living animal (Fig. 1A) has a very elongated, pseudoannulated prostomium with four antennae of equal length and, on its posterior margin, two eyes. The proboscis is about three times as long as the prostomium and is covered with fairly large, round papillae which are not arranged in rows. The first two segments carry three tentacular cirri and are apparently free from each other, although a separation could not be clearly seen mid-dorsally. The cirrus on the first segment, and the dorsal one on the second segment, are long and slender, whereas the ventral cirrus on the second segment is ovoid and hardly larger than the ventral cirri on the setigers. All tentacular cirri are placed on cirrophores. There are no bristles or aciculae on the second 1 Contribution No. 290 from the Department of Oceanography, University of Washington, Seattle 5.
