Marine Leeches of the Eastern United States and the Gulf of Mexico with a Key to the Species
Unlike the Eurasian marine leeches (Johansson, 1896; Selensky, 1915; Herter, 1935; Vasileyev, 1939; Knight-Jones, 1961; Sawyer, 1970; Soós, 1965), those from North America comprise an unusually neglected group, due primarily to the bewildering taxonomy of the members. Most early descriptions were br...
