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

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 ;

as in shells brought from the Indian Ocean. It is very common, 
but in collections is almost always found discolored, and en-

p. 171, No. 488, fig. 50, is the same as the Buccinum gib- 
bosulum.
