Dear Gary and all,

What is the status of the "Addition material studied"? Is this considered type
material.?

When revisers of a type lot find that there are more than one species, is it
permitted to change any of the original labels in a collection?
Should any new labels or notes, signed by the revisers be added to the original
collection?
I cannot ever imagine that the originals should be substituted  or even
re-copied.

If the additional material includes anatomical parts of the mollusc, eg.
Radula, stylet etc. is it compulsory to deposit samples of this material with
the new types?

Are there any new regulations concerning electrophorensic results of material
studied when published as evidence with a new species description or as
distinction between two very similar species? In the latter case what should
the type material consist of?

Regards,
