Grygier Abstract. —An inventory is given of the echinoderm-parasitizing dendrogas-trid Ascothoracida studied by V. L. Wagin that are housed in the Zoological Institute, U.S.S.R. Academy of Sciences, and the Department of Invertebrate Zoology, Leningrad University. Complete locality data for most of these Arctic and boreal Pacific species are given for the first time. Lectotypes are designated for one species of Ulophysema and eight species of Dendrogaster, and the asteroid hosts of D. astericola, D. dogieli, and D. beringensis are reidentified as Henricia skorikovi, Pteraster octaster, and Eremicaster crassus, respectively.

The Dendrogastridae include three gen-era of crustacean endoparasites of echino-derms (Grygier 1987). Wagin (1950b, 1957, 1976) conducted taxonomic studies of 13 species of Dendrogaster infesting Asteroi-dea, mostly from the vicinity of Sakhalin and the western Bering Sea, and he pub-lished one record (Wagin 1964) of echinoid-infesting, Arctic Ulophysema. The Pacific specimens were collected by A. V. Ivanov in 1931 and 1932 and by Wagin himself in 1947 and 1950. Wagin's publications were usually unspecific about collection data and deposition of specimens, often mentioning only the year, station number, and host, and he never designated any primary types. Two partial compilations of Wagin's findings (Lindberg 1959, Barel «fe Kramers 1977) did little to clarify matters. The following is an inventory of the extant material of each spe-cies in Leningrad and its condition, with full locality data and lectotype designations in most cases. Materials.— In 1985 I examined the type lot of Ulophysema pourtalesiae Brattstrom in the Zoologisk Museum in Copenhagen and borrowed specimens of Dendrogaster astericola Knipowitsch and D. murmanen-sis Wagin from the Zoological Institute (ZIN) in Leningrad. During a visit to the ZIN in 1989 I was able to examine abundant cat-alogued material of Dendrogaster, as well as uncatalogued specimens that had been transferred from Kazan University after Wagin's death in 1984. All of the pertinent species of Dendrogaster were represented and I could match many specimens with Wagin's illustrations; the glass-plate nega-tives of Wagin's (1950b) photographs were also present. However, some specimens and almost all of Wagin's microscopical prep-arations were missing. At Leningrad Uni-
