Conus aulicus, common name the princely cone, is a species of a predatory sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones.[1]
The size of an adult shell varies between 65 mm and 163 mm. The shell is rather narrow and has an elevated spire. The color of the shell is chocolate-brown, covered by elevated close revolving lines of darker color. The surface is irregularly overlaid by subtriangular white spots, some of which are very large. The operculum is a very minute square on the dorsal surface of the hinder part of the foot.
The proboscis of Conus aulicus is varied with red and white.[2]
This marine species occurs in the Indian Ocean off Chagos[1] and Mauritius;[1] in the Indo-Pacific Region (excl. Hawaii).
