FIGURE 2 in First record of genus Orbiniella Day, 1954 (Polychaeta: Orbiniidae) in North Atlantic Ocean with the description of a new species
FIGURE 2. Illustrations of described species of Orbiniella sorted by date of original description (redrawn from Day 1954; Hartman 1967; Hobson 1974; Blake 1985; Blake & Hilbig 1990; Buzhinskaja 1993; Branch 1998; Gillet 1999; Narayawasmany & Blake 2005).
