Appendix rv 189 



characters with Case IV and V distributions, I have changed the polarity assessment to 

 undeterminable, since the new outgroup evidence is compatible with either polarity 

 inference. For characters with Case VI distributions, I have reversed the polarity, because 

 the new outgroups suggest that either the old polarity is incorrect for the less inclusive 

 ingroup or the situation is equivocal.
