in xl and x2, non-zero elements of a finite field F(p') of order pn, p an odd prime with C1, C2, C3 given elements of F(p'), c1c2c3 $ 0, in certain special cases. Secondly, we shall find limits (Theorem II) for the number of solutions of (1) which are better than those given in C for the solutions of this particular equation, and which have the unusual property that they agree with the exact values found for the number of solutions in the special cases treated in Theorem I. We shall employ the notation used in H (defined in (9b) just below relation (14) of that paper). Let a be a primitive (dsls2)-th root of unity, m = ds1s2 where ds, = k12 ds2 = k2 where (k1, k2) = d, whence (sl, s2) = 1. Let X-1 be a special kicharacter and xt, a special k2-character in F(p') and write, if K stands for F(p'),
