Abstract :In [1] the main result insert ignore into journalissuearticles values(Teorem 2); which States that “a submanifold Mn of a RiemanSian maniforld Mn is an extrinsic sphere insert ignore into journalissuearticles values(i.e. the submanifold which is umbilic and has parallel mean curvature); iff every circle in Mn is a circle in Mm must have some additional hypothesis. We pointed out these hypothesis just the special case of Mm — IRm
