Cassis cornuta (Linnaeus 1758), the Horned Helmut. One of four species found in Hawai'i. Common in shallow sandy environments. Found buried in sand with only whorls in evidence. Largest Hawaiian Helmut (to 15"); used as a "blow horn" by natives in shows. Some authors believe specimens with fewer, higher horns are males, shorter, more numerous females. Kona pix.
