The brachiopod fauna of the East Coast of the United States at present numbers 17 genera (4 inarticulates and 13 articulates), of which 11 are discussed herein (asterisk): 2 linguilidids: Glottidia,* Discradisca; 2 craniidinids: Isocrania?* and Crania?*; 2 rhynchonellids: Probolarina* and Cryptopora, the former extinct; 2 cancellothyrids: Eucalathis* and Terebratulina*; 5 extinct terebratulids: Embolosia, Oleneothyris, Plicatoria,* Rhytisoria,* and Tanyoscapha; 2 terebratellids: Argyrotheca* and Platidia; and 2 thecideids: Lacazella* and Thecidellina.* Pliocene Glottidia inexpectans Olsson in adult form is described. New species of Probolarina, Terebratulina, Argyrotheca, Lacazella, and Thecidellina are described and illustrated. Specimens not identified as to species are described: Crania,?, Isocrania?, Eucalathis?, and Terebratulina. The remarkable variation of Plicatoria wilmingtonensis (Lyell and Sowerby) is described and illustrated.
