Conus magus

Conus magus (syn.:Conus fulvobullatus) shows the variability in pattern and color of this species

The size of an adult shell varies between 16 mm and 94 mm. This common species is very variable in pattern and shade of coloring and embraces a large synonymy. The moderate spire is striate. The body whorl is long and rather cylindrical, closely striate below. The color of the shell is white, clouded with bluish ash, orange-brown, chestnut or chocolate, everywhere encircled by narrow chocolate interrupted lines, often separated into somewhat distant dots The middle of the body whorl is usually irregularly fasciate with white. The spire is tessellated with chestnut or chocolate.[3]

This marine species occurs in the Red Sea and in the Indian Ocean off Madagascar and the Mascarene Basin. It is also found over a wide area of the Pacific Ocean from Indonesia to Japan and to the Marshall Islands, Wallis and Futuna and Fiji, but mainly centered on the Philippines; off Australia (Queensland).
