The continuation of the list of long-lasting SXR flares (LDE-type) from May 1990 to October 1991 is given in a computer-file form. The LDE-type flare occurrence (of M and X-SXR classes) on the whole solar disk (D) and in the northern (N) and southern (S) hemispheres, is considered. The maximal monthly occurrence of LDE flares in January 1989 (N(D)=68, N(S)=55) and March 1991 (N(D)=67, N(S)=62) belongs to the southern solar hemisphere. In March 1989 (N(D)=60, N(N)=52) the maximal northern occurrence was observed.
