UNIVALVES STROMBUS. 



75 



Strombus, from the fens of Amboyna; and Strombus 

 Aculeatus or Black Hercules' Club, from the marshes of 

 Africa. 



It may be observed, that the three last are land species, 

 and are characterized by their elongated or turreted 

 shape, and having their whorls more or less beset with 

 sharp knobs or prickly spines. One species of Strombus 

 is remarkable for having its whorls turned contrary, it is 

 the Strombus Sinister, or Left-handed Strombus, and is 

 found fossil in Helvetia. 



The Strombus Spinosus is also found fossil. Tlie Strom- 

 bus Fissurella is sometimes to be met with in India, in a 

 recent state, but is more frequently found fossil in Cam- 

 pania and in England. 



The African, Indian, American, and European oceans, 

 alike furnish their supplies of this genus, and some few 

 are indebted to the Mediterranean, Red, and Arctic Seas 

 for their existence.
