Query: The Structure Theorem for The cut locus of a Certain Class of Cylinders
  of Revolution II   In the previous paper, the structure of the cut locus was determined for a
class of surfaces of revolution homeomorphic to a cylinder. In this paper, we
prove the structure theorem of the cut locus for a wider class of surfaces of
revolution homeomorphic to a cylinder.
