AbstractIn order to study the functorial composition of species, we introduce the auxiliary concepts of cyclic type and fixed points enumerator of a species. Basic formulas are established and applications are given to the computation of the cycle index series of classes of graphs, pure m-complexes, coverings and m-ary relations that are structured in various ways
