This paper is a continuation of the study of subvarieties of the variety of Birkhoff systems originated in the first paper by the authors with the same title [ibid. 34, No. 1, 45--68 (2017; Zbl 1362.08002)]. It contains a description of 4-element subdirectly irreducible Birkhoff systems and a description of of the poset of varieties generated by finite splitting bichains. A structure theorem for one of the five covers of the variety of distributive Birkhoff systems is given.
