 This well known shell generally rather exceeds three inches in 

 length, and is about an inch and three quarters broad ; the 

 whole of the external surface is white without any markings 

 and the inside is brown, and it differs from the Cypra£e & in 

 little besides the teeth being wanting in the inner lip. Its 

 common name is the Poached Egg.
