UNIVALVES. CYPRJSA. 85 



zigzag lines, undulations, streaks, &c. ; which are beauti- 

 fully exemplified in the C. mappa, the C. argus, and the C. 

 testudinaria. To these may be added the C. vitellus, the 

 C. carneola, the C. talpa, and others of the like description. 

 Some of the species, however, have but little colouring, 

 and have their surfaces covered with small globular tuber- 

 culations or warts, as the C. pustulata. 



One of the largest and most valuable Cowries is the C. 

 aurora, or orange cowry, which is found, though very 

 rarely, at the Friendly Isles. Of the smaller cowries > the 

 C. stolida and the C. pustulata are considered rare. 



The greater proportion of the Cypraese are found in the 

 Indian ocean; many, however, come from the American, 

 African, and Mediterranean shores; some also from the 

 South seas.
