This work continues the study of the subgroups of totally imprimitive groups of finitary permutations which was started in [1]. Here some characterizations of non-FC-subgroups and subnormal subgroups of stabilizers of these groups are obtained, and the nontriviality of the core of G in the normalizers of blocks is shown.
