This paper is a continuation of the paper described in the preceeding review. The main result is that a pseudovariety of semigroups is permutative if and only if it does not contain any semigroups from a certain list of eight types. The pseudovarieties generated by each of the semigroups S in the list are minimal non-permutative and admit the corresponding S as a generator of minimum size.
