Dear James, here is a list of rare or at least very uncommon Naticidae you might include in your compilation. Most Naticids are rather abundant, and even for the "rare" ones it might just be a question of stumbling across their exact habitat before they become "common" as well. Of course, there are plenty of Naticids known only from the Holotype, but many of those taxa are disputed as to their validity. The ones listed below at least are undisputed good species: Aloconatica kushime Shikama, 1971 [Japan] Natica inexpectans Olsson, 1971 [Panamic] Sigaretotrema inflata (Tesch, 1920) [Western Pacific] Euspira fringilla (Dall, 1881) [Caribbean] Euspira nubila (Dall, 1889) [Caribbean] Haliotinella patinaria Guppy, 1876 [Caribbean] Sinum noyesi Dall, 1903 [Panamic] Natica perlineata Dall, 1889 [Caribbean] Regards, Michael Hollmann ****************************************** Prof. Dr. Michael Hollmann Goerdelerweg 17 D-37075 Goettingen GERMANY Tel.: (home) (49)-551-58468 Tel.: (work) (49)-551-3899-437 FAX: (work) (49)-551-3899-644 e-mail: [log in to unmask]
