Art Weil wrote, "Dear James;- "Interestingly, Dr. Zeigler in his 'Olive Shells of the World' leaves a space vacant for a photo of O. aniomina when '---ones comes available.' How many examples was that described from----and where are they? "The Q. Man" This is yet another questionable practice in taxonomy. O. aniomina is a "conditional name"--one that is proposed on condition that specimens or information about them are found later. Article 15 of the International Code of Zoological Nomenclature (1985) says, in part, "A scientific name or nomenclatural act proposed conditionally after 1960 is not thereby made available [i.e., valid]; conditional proposal before 1961 does not prevent availability..." But aside from that, the author of any new species name has to follow several other rules as well, so this name probably is unavailable for taxonomic use. Andrew K.
