Yes, very interesting, but I don't know what is "against" describing from
one species. I just described with Brulet a Morum from one specimen, and
Dance and Emerson (redescribed) watsoni from a single juvenile. If they are
different enough from all others.
Also, Petuch is apparently specialised in describring species, but all by
all he described more valid things than not valid things. So, even if there
is a 30 % loss and overcharge of literature, his contribution is all right.
About the turbinum: I had one and it went to Saito, Japan, about 5 years ago.
And about the scalariformis Strombus: does it exist or not ? It is
apparently close to haemastoma. So, about 10 years ago, this was just
before I got the small Dutch book on Strombus where there is a black and
white drawing, I dived a small Strombus south of Santa Rosa Island (you
know, Olango they sometimes call it), in 1 m of water. Cleaning out the
material in Belgium, I trew it in the ashtray, because "looks like a dead
haemastoma". When the book arrived, I could tear my hairs out, and a
hundred dives later on the same spot I couldn't find another one.
