None. Begins: "This study was made during the summer of 1940 with the facilities and permission of the U. S. Fisheries Laboratory at Beaufort, North Carolina. Work was limited largely to the intertidal areas in the vicinity of Pivers Island, near Beaufort; some dredging and trawling were done in a few feet of water in Bogue Sound and in 45 to 75 feet outside of Beaufort Inlet. In many instances data are given regarding unusual associations and commensalism, habits of tube-building, stage of maturity of individual species, colors in life or other phenomena that might aid in the ready identification in the field or with the aid of ·low magnifications. One hundred and four species of polyehaetous annelids are reported from eastern United States, largely from the vicinity of Beaufort, some new for this region, others for the first time from eastern North America, and a few unique to Beaufort. All except two species were collected during the preparation of this report. Two new genera, six new species or subspecies, and seven new combinations are proposed; another species is revised, based on type material. Some species that have remained unknown except through an early brief account have been reidentified, and some have had their ranges extended. A considerable number of species are now believed to be common to an area extending from New England south through the West Indies; others range from North Carolina south through the West Indies or even Brazil; some are common to North Carolina and the subtropical eastern Pacific; comparatively few species are cosmopolitan, and a few are known only from the Carolinas.
