| Abstract: | Paraustrorhynchus gen.n., P. pacificus sp.n. (California), Antiboreorhynchus novzelae sp.n. (New Zealand) and Gyratrix proaviformis sp.n. (Oregon) are described as new taxa. Additional notes are given on Gyratrix hermaphroditus Ehrbg. (new localities on the N. American Pacific coast), Scanorhynchus forcipatus Karling (new locality in California), Paraustrorhynchus elixus (Marcus) comb.n. and Alcha evelinae Marcus (new localities in California). The taxonomy of the genera and species is discussed. Viewpoints are presented on evolutionary trends and homologous atrial organs in the family Polycystididae. |
