You are admiring a longtime favorite of mine & Murex collectors worldwide, a Murex troscheli (Lischke, 1868), w/operculum, measuring 127.8mm (or 5") and graded F+++...an absolutely incredible & most elegant form with the most beautiful, super long spines & a spectacular color pattern is displayed on this deep H20 masterpiece. This beauty was collected in tangle nets at 150-250m off Balicasag Island, Philippines. Also known as Troschel's Murex, this member of the Muricidae family will be a treasured addition for your collection. Thank you for visiting our store this afternoon...and an excellent choice, too.
