species they appear to constitute a very natural genus, distinguished by 

 their large tubercular growth and brilliant display of colours ; there is also 

 a character in the style of marking which obtains some importance from 

 the circumstance of its being generally accompanied by numerous transverse 

 lines in a manner pecuhar to the genus, whilst the aperture is usually 

 closely radiated with elevated hues. The columella of the shell is in this 

 genus distinguished by one or two plaits ranging obhquely at the base. 



The Fasciolaria are pretty generally distributed, being found in Ceylon 

 and the Philippine Islands, Australia, Western Africa, Panama, Mexico, 

 and West Columbia, Honduras and the West Indies, the Mediterranean, 

 Cape de Verd Islands, &c.
