Dear Carol Saw your note, what a fascinating species! Epitonium pourtalesii is quite a rare species. I have one specimen (29mm) dredged off Key West in about 90 fms. It is indeed similiar to E. krebsii but different, the best discription of it is in Johnsonia vol. 2. It was lumped by Bouchet but like E. lamellosum the shells have fairly different shapes from each area. Our species from the Western Atlantic in my opinion appears to be much more sculptured, with highly developed costae. Regards, Kevan Sunderland
