We study some K3 surfaces obtained as minimal resolutions of quotients of subgroups of special reection groups. Some of these were already studied in a previous paper by W. Barth and the second author. We give here an easy proof that these are K3 surfaces, give equations in weighted projective space and describe their geometry.
