[In translation] Collections of polychaetes from the eulittoral and upper sublittoral zones of the Galapagos Islands (1972–73) yielded 41 identified species belonging to four families of the Errantia. Of these, two belong to the Pisionidae, four to the Hesionidae, and one to the Pilargidae; the remaining 34 are Syllidae. Almost all are representatives of the meiofauna. However, fewer than half are true mesopsammic forms; a large proportion belongs to the epilithon, endolithon, and phytal zones, while the rest live on the surface of sublittoral sediments. Thirteen species and five subspecies are new to science, and five species were identified only to the genus level. Nineteen species were already known—one of which was reassigned—and three had been reported previously from the Galapagos Islands. The known species consist predominantly of polychaetes with a broad, circumtropical, or cosmopolitan distribution; this applies particularly to some of the interstitial forms.
