over k. Then the genus of C(r,s) is (q―l)j2 and C(r,s) has an automorphism o order q. In §1, we shallgive a basis of the space 01 differentialsof the firstkinc on C(r,s),in forms suitable to our later use. In §2, we shall give a conditioi under which C(r,s)fsare isomorphic in terms of r and s. This is our main result In particular,we see that the cardinalityof the set of isomorphy classes is,(#+5)/i if q=\ mod 3, and (#+l)/6 if q=2 mod 3. In §3, we determine the order of tin group of automorphisms of C(r,s) in the case of characteristiczero. The auther should like to express his sincere thanks to Dr. T. Sekiguchi an< Dr. M. Homma for their encouragement during the preparation of this paper.
