Dear Bill, I saw this species in Abbot and Sanstroms Seashells of North America, page 45. It is an illustration of a typical shell label, and on it, clear as day, it says Conus sonnei. It may be a mistake, but I don't know why they would write it twice, on the sample label and in the notebook picture, unless they just made it up, which I doubt. Anyway, I thank you for your help! Kind Regards, James
