Thanks Paul.  I received your PDF file with the article.  It will take some
time to digest.  As you know I am a layperson* in this matter and my
presentations are intended to reflect my understanding and integration of
material into a format and grouping for my use and now to share with other
lay-collectors.  I know I make errors for lack of my scientific/technical
training, and that is why I request and appreciate comments from the Conch-L
membership that includes so many with such training.  The content on my
website is edited and updated as a result of these comments.

*Definition: non-expert; someone who is not a professional person; amateur.
The term layman originated from the use of the term laity, but over the
centuries, changed definition to mean "a person who is a non-expert in a
given field of knowledge."  The concept of describing something in layman's
terms has come into wide use. It means to describe a complex or technical
issue in terms that the average individual (someone without professional
training in the subject area) can understand.

Marlo,

In following this nomenclatural thread, although I'm well aware of your
website, I have just become aware of your listing of terms and definitions
of various "types." Your efforts at compilation of such terms is superceded
only by your efforts to make them available to all via your website.
Thanks!

That said, and in response to you welcoming comments, I suggest that you
mention (on your web page) a most important reference article which
published a whopping! 32 pages of definitions of various "type" terms as
well as discussions of their availability, use, and misuse.  This article is
well known to some, but also totally unknown to many.
