> Note 11.1.1, which is referred to in Note 13.2.2, was changed by CPN  
> vote in January (see the attached changes in Art. 11 that were  
> approved by the CPN).  Before these changes were approved, Note  
> 11.1.1 read as follows  (i.e., in version 4c, currently still  
> online): "When a species is cited as a specifier, the implicit  
> specifier is the type of that species name (if a type has been  
> designated) under the appropriate rank-based code."

> The concept of an implicit specifier was removed from the code when

> another definition that uses the type specimen of that species would
