    In the fourth paper from the author's series [ibid. 43, 347-363 (1984; Zbl 0546.54004) and 44, 279-297, 299-310 (1984; Zbl 0569.54001 and Zbl 0569.54002)] devoted to the study of preordered syntopogenous spaces regularly preordered, completely regularly preordered and normally preordered syntopogenous spaces are treated. The author also shows that one lemma (Lemma 3.1) from the paper by \textit{M. K. Singal} and \textit{S. Lal} concerning local proximity preordered spaces [Math. Stud. 41, 269- 275 (1973; Zbl 0339.54029)] is false.
