The nuclear genes of ciliates also have a non-standard genetic 
code where two stop codons encode glutamine if I remember correctly.
There is a very recent paper by Baroin Tourancheau et al (1995) 
EMBO J. 14 (13): 3262-3267 where the authors show that there were
multiple independent origins of this usage in ciliates.
