Some of these are as follows (from G. G. Simpson, 1961, Principles of Animal Taxonomy, Columbia Univ. Press): Kingdom Phylum (often Division in plants) Subphylum Superclass Class Subclass Infraclass Cohort Superorder Order Suborder Infraorder Superfamily Family Subfamily Tribe Subtribe Genus Subgenus Species Subspecies To these, biologists now often add superspecies, and increasingly semispecies (as between Species & Subspecies), though originally semispecies were just species that were members of a superspecies complex. Allospecies are members of s superspecies complex. I'm sure there are others. --Jim Rising -- Name: Jim Rising Mail: Dept. Zoology, Univ.
