Holmquist, Ch. and Karling, T. G. (Section of Invertebrate Zoology, Swedish Museum of Natural History, Stockholm, Sweden.) Two new species of marine triclads from the North American Pacific coast, with comments on evolutionary trends and systematics in Tricladida (Turbellaria) . Zool. Scripta 1(3–4): 175–184, 1972.–Two marine triclads, Oregoniplana opisthopora gen. et sp.n. and Pacificides psammophilus gen. et sp.n. are described from the Pacific coast of USA. They are inhabitants of sand in the surf zone. They are provisionally included in the family Procerodidae but their anatomy is aberrant in several respects; they elucidate some evolutionary trends as well as some unsatisfactory points in the systematics of the aquatic triclads.
