Chen and Lue (2007) initiated the study of spherical submanifolds with finite type spherical Gauss map. In this paper, we firstly prove that a submanifold M-n of the unit sphere Sm-1 has non-mass-symmetric 1-type spherical Gauss map if and only if M-n is an open part of a small n-sphere of a totally geodesic (n+1)-sphere Sn+1 subset of Sm-1. Then we show that a non-totally umbilical hypersurface M of Sn+1 with nonzero constant mean curvature in Sn+1 has mass-symmetric 2-type spherical Gauss map if and only if the scalar curvature curvature of M is constant. Finally, we classify constant mean curvature surfaces in S-3 with mass-symmetric 2-type spherical Gauss map.
