“As stated above, the method of ‘correcting’ an author’s 
measurements to force them to agree with what species we 
will is essentially unscientific. It savors of medizval theolog- 
ical procedure. If great dependence is placed upon these pro- 
portions in some cases, why throw them away when they do 
not suit our convenience? In the case of Unio teres, its adop- 
tion would mean the rejection of certainties for a name resting 
on a description requiring arbitrary alteration, and after that, 
practically arbitrary selection between two closely related 
forms. U. teres should be discarded as not identifiable.” (H.
