Two new species of nudibranch mollusks from the Gulf of the Farallones and Cordell Bank national marine sanctuaries, central California

Two new species of nudibranchs are described from the central coast of California. Armina cordellensis is unique among described taxa in having low tubercles not arranged in distinct longitudinal rows. The radular teeth are elongate and minutely denticulate. Aeolidia farallonensis is unique among described species in possessing a lateral anus and irregularly rugose rhinophores. The jaws are proportionately larger than in other described species. The anal position is situated ventral to the notum, a feature that is unique among described members of the Aeolidiidae.
