Probably something that will go away when we quit using Bio::Species  
altogether (in favor of Bio::Taxon) after 1.6.   I'm not sure whether  
it will be worth the trouble, but it's worth discussing.

Anyway, I'm still a bit unfamiliar with some aspects of Bio::Species  
(and I'm pretty busy ATM) so it make take a few days.
