The color is olive or of a brown fawn-color and ash, sprinkled 

 with spots or clearer undulated lines ; sometimes one or two 

 transverse brown bands surround the lowest whirl. The edge 

 of the callosity is always of a more or less deep orange color. 



Length 8 lines. Width 6 lines. 



Inhabits the Mediterranean, upon the shores of Corsica, and 

 the Asiatic seas. 



This shell varies in its form, which is more or less rounded, 

 and in its coloring, which is often uniform, although those are 

 found from the Mediterranean, which are of an ash-gray color ; 

 at other times deeper, and marked with numerous spots, such 

 as in shells brought from the Indian Ocean. It is very common, 

 but in collections is almost always found discolored, and en- 

 tirely white. The EIONE gibbosula of Risso, Europe merid., 

 p. 171, No. 438, fig. 50, is the same as the BUCCINUM gib- 

 bosulum.
