Section 8 says:

   The resulting filling of N1 and N2 is added in the CM5 modulo 2 with
   the third block Tp(3), etc., the last block Tp(M) = (t1(M), t2(M),
   ..., t64(M)), padded if necessary to a complete 64-bit block by
   zeros, is added in CM5 modulo 2 with the filling N1, N2 (a1(M-1)[16],
   a2(M-1)[16], ..., a32(M-1)[16], b1(M-1)[16], b2(M-1)[16], ...,
   b32(M-1)[16]).

It should say:

   The resulting filling of N1 and N2 is added in the CM5 modulo 2 with
   the third block Tp(3), etc., the last block Tp(M) = (t1(M), t2(M),
   ..., t64(M)), padded if necessary to a complete 64-bit block by
   zeros, is added in CM5 modulo 2 with the filling N1, N2 
   (a1(M-1)[16], a2(M-1)[16], ..., a32(M-1)[16], b1(M-1)[16], 
   b2(M-1)[16], ..., b32(M-1)[16]).
