Scott,
 
In Hawaiian Shell News, November 1979, page 3 is an explanation of why
you can't find the name "Conus pramparti" in reference books.  To quote
the article..."A very attractive golden yellow cone made its appearance
about 1975...it was thought at first to be a variety of Conus barthelemyi
Bernari, 1861.  Subsequently, however, it was referred to as Prampart's
Cone.  Georges Richard, of the National Museum of Natural History, Paris,
was informally credited with having described it, or was said to be about
to do so.  the name appeared in some dealer's lists, sometimes as a
provisional species and more often without qualification."
 
The article then refers the reader to another article on the same page by
Bob da Motta reporting that this cone had not been described by Mr.
Richard, or anyone else for that matter.  The shell in question was named
Conus leehmani da Motta and Rockel, 1979 in the May/June issue of La
Conchiglia.  Rockel and his co authors now consider Conus leehmani a form
of Conus gubernator in the Manual of the living Conidae.
 
Hope this explanation helps clear up the mystery.
