We examine the canonical forms of Painlevé equations and argue that the equation for PIII in which one parameter is taken to be equal to zero should be considered as a canonical form different from the standard PIII . Our argument is based on the fact that the value of this parameter cannot be modified through auto-Bäcklund transformations. We investigate the possible discrete forms of this equation and produce two of them. One is of a difference type, where the independent variable enters linearly, while the second one is of q type where the independent variable enters in a multiplicative way. The properties of these discrete equations are also studied.
