A partial revision of the bipalpate cirratulid genera is proposed based upon an examination of type material and new collections from the U.S. Atlantic continental shelf, slope, and rise. Syn types of the type species of Tharyx, T acutus Webster & Benedict, 1887, have been found to possess neuropodial knob-tipped spines; the species thus does not agree with the concept of Tharyx as usually understood, i.e., where species have only capillary setae. Based upon this observation, Tharyx is redefined to include species having capillaries and irregular knobtipped spines. Those species having only capillaries with a sawtooth edge are referred to Monticellina Laubier, 1961, while those having capillaries with smooth edges are referred to a new genus, Aphelochaeta. Tharyx acutus is redescribed and a new species, T kirkegaardi, is described. Tharyx dorsobranchialis (Kirkegaard, 1959) is redescribed and referred to the genus Monticellina. Tharyx annulosus Hartman, 1965 and Monticellina heterochaeta Lau bier, 1961 are referred to synonymy with M. dorsobranchialis. A new species, M. baptisteae, is described.
