Abstract: Let $M^n$

be a closed hypersurface of constant mean curvature immersed in the unit sphere $S^{n+1}$ . Denote by $S$

the square of the length of its second fundamental form. If $S<2\sqrt {n-1}$ , $M$

is a small hypersphere in $S^{n+1}$ . We also characterize all $M^n$

with $S=2\sqrt {n-1}$ .
