This primer was organized by Dr. Larry Spencer of the Natural Science Department, Boyd Hall, Plymouth State College, Plymouth, NH 03264. The information was gathered by the members of his Invertebrate Zoology Class, Fall 1994. The pages were updated by two independent study students in 1995 and have been modified since then by me. The classification is after the scheme used in Pechenik.
