Variety. With the margin raised higher than the back, and 

 not nodulous. 

 Cyprgea obvelata. Lamarck Ann. du Mas. xvi. p. 102. 



Inhabits the Mediterranean, Atlantic, JEthiopic, and Indian 

 Seas. Gmelin. The Variety comes from the coasts of New 

 Holland. Lamarck. 



Shells varying from half an inch to an inch in length, and two 

 thirds as broad ; white or yellowish, without any coloured 

 markings except sometimes a yellow ring similar to that of 

 C. Annulus, from which species this Variety may be known 

 by the protuberant knobs on its margin. Worn shells are 

 blue on the back, as is represented in Martini's fig. 

 339. Linnaeus says, that in the Maldives these shells are 

 fished up by the Negro Women three days before or after 

 the full moon, and sent into Bengal, Siam, and other coun- 

 tries to be used as money. Vast quantities are imported 

 into this country for the purposes of traffic, and it is said 

 that as much as one hundred tons of them are sent annually 

 to Guinea alone. The Variety is intermediate between C. 

 Moneta and C. Annulus. 



annulus. 46. Shell ovate, gibbous, with the back 

 surrounded by a yellow ring, and the margin 

 smooth.

 Inhabits the coasts of Amboyna. Rumphius. Alexandria. Lin- 



naus. East Indies. Humphreys. 

 Shell generally near an inch long, and rather more than two 

 thirds as broad, white or greyish yellow, and marked round 

 the back by a yellow ring. The back when decorticated be- 

 comes blue as in C. Moneta, but the margin is less flattened, 

 and the knotty protuberances, which distinguish that species, 

 are wanting:.
