Excerpt: ... The uncini of the anterior region have a large, sharp, rostrate hook, directed somewhat upward, and three (sometimes four) small appressed apical hooks. Color, in life, is light red in the smaller specimens, and with no definite red bands. The large ones were yellowish brown. The tubes are made of fine shell-sand, and stand upright in the sand at low-tide. In life the smaller specimens were about 50mm long and 0.5mm in diameter, the larger ones about 150""n long and 4-5mm in diameter. In consequence of the modern revisions of the Maldanidae by St. Joseph and others, it will be necessary to establish additional generic groups. The common, large New England species described by me (1873) as Maldane elongata cannot be placed in any of the recognized genera, and I therefore propose to establish a new genus for it. Maldanopsis, gen. nov. Type M. elongata V., 1873. Head with a well formed limbate cephalic plate, as in Maldane. Caudal segment with a wide, prominent foliaceous spatulate lobe on the dorsal side, and on the ventral side a deep, funnel-like, anal opening, surrounded by a distinct semi-circular rim, without denticulations, so that the anal opening is inside the margin of the anal plate, and not outside, as in Maldane. This plate is, therefore, more like that of Petaloproctus. The anterior setigerous segment has no uncini; the 2d and 3d have short rows of rostrate uncini. All preanal segments bear setae. Lumbriclymene filifera Ver. The Maldane filifera V., 1879, Proc. TJ. S. Nat. Mus., p. 119, does not belong to Petaloproctus, as St. Joseph supposed, but rather to Zntmbriclymene Sars, 1871, but it differs from the type, so that the generic characters should be altered somewhat. Its anal region consists of a somewhat flattened cone, turned up dorsally and nea...
