complex existing codes, the matter is less simple. I believe 
it is best to follow the code wherever we can do it without 
confusion ; but to anticipate the likelihood of a conservanda 
decision in many cases where a strict interpretation of the 
code would seem to overturn a well-known name, and con- 
tinue to use the current name in the interim, till the prepa- 
ration and decision of a case before the Commission is pos- 
sible. But when a definite decision leads to a definite name, to 
accept the decision as promptly as possible. A decision which 
leaves a residual ambiguity, as in a recent notable case, I 
should not interpret as a final decision. 
We end, then, much as we began under Linnaeus; with 
Authority, qualified by Judgment, especially where authority 
does not lead to an unambiguous result; following Priority 
as far as practicable, but not making it the final arbiter.
