Dear friends As far as I know, recent genetic studies have shown that the conus genus is monophyletic, so I believe that genus or subgenus have no taxonomic value, although the mentioned "genus" (i.e asprella, cucullus, cylinder, etc) migh be useful for organising a collection. A different story is the occurence of different genus within Conidae (i.e. Conorbis). Very recently, according to Bouchet and Rocroi 2005, a number of genus previously included in turridae are now in Conidae. Please correct me if I am wrong Warmest regards to all Manuel Jimenez Tenorio ---------------------------------------------------------------------- [log in to unmask] - a forum for informal discussions on molluscs To leave this list, click on the following web link: http://listserv.uga.edu/cgi-bin/wa?SUBED1=conch-l&A=1 Type your email address and name in the appropriate box and click leave the list. ----------------------------------------------------------------------
