NATIONAL MUSEUM Vol. 86 Washington : 1938 No. 3046 THE TYPES OF THE POLYCHAETE WORMS OF THE FAM-ILIES POLYNOIDAE AND POLYODONTIDAE IN THE UNITED STATES NATIONAL MUSEUM AND THE DE-SCRIPTION OF A NEW GENUS By Olga Hartman A SURVEY of the types of annelids of the families Polynoidae and Polyodontidae in the United States National Museum indicates the necessity of several nomenclatorial changes. The first part of this paper is a discussion of some of these types and a revision of some of the genera concerned. The second part lists all the types in the Museum, with changes of names and new combinations indicated. For convenience, type locality, place of publication, and museum catalog number are given. Family POLYNOIDAE Genus IPHIONE Kinberg IPHIONE FUSTIS Hoagland Figure 35, a Iphione ftistis Hoagland, 1920, p. 605 (U.S.N.M. no. 18941 ; Philippine Islands). The type may be an immature individual, as already stated by Hoagland. The paired prostomial antennae have their cirrophores and cirrostyles subequal. The place of articulation was not indicated by the describer, but the total length is about as shown. Neuropodia are considerably more oblique that Hoagland has shown, and the neuropodial aciculum projects beyond the Darapodial lobe ; neurocirri are long, digitiform (fig. 35, a). 87105—38 1 107
