The author discusses the relationship between the following two types of fuzzy Hausdorffness: one given by \textit{R. Srivastava}, \textit{S. N. Lal} and \textit{A. K. Srivastava} [ibid. 81, 497-506 (1981; Zbl 0491.54004)] and another introduced by \textit{P. M. Pu} and the reviewer [ibid. 76, 571-599 (1980; Zbl 0447.54006)]. Some counterexamples are also given.
