>
> Please send your votes to the listserv on the following questions:
> 1) Should Note 13.2.2 be deleted?
> 2) Should the proposed changes in Rec. 21.3A Example 1 and Note
> 21.3A.1 be adopted?
>
> Please vote by the end of the day on Friday (April 12).

> Art. 13.2 and Note 13.2.2 currently read:
>
> 13.2. Phylogenetic definitions are considered to be different if
> either: 1) they are of the same kind (e.g., node-based,
> branch-based, etc.) but cite different specifiers and/or have
> different restrictions specified in their qualifying clauses (if
> any), or 2) they are of a different kind.
>
> Note 13.2.2. A species and its type specimen are considered to be
> the same specifier (see Note 11.1.1).
>
> 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
> the CPN revised Art. 11. With the changes that have been approved
> in Art. 11, a definition that uses a species name as a specifier and
> another definition that uses the type specimen of that species would
> be considered different under Art. 13.2 because they have different
> specifiers. An indication that they are truly different is that the
> consequences of their use differ under certain situations discussed
> in new Arts. 11.4 and 11.6. Kevin and I are therefore recommending
> that Note 13.2.2 be deleted.
>
> Let's give ourselves until Monday to discuss this. If the
> discussion appears to have ended by then, I will call for a vote
> next Tuesday.
