110 AMERICAN JOURNAL 



The Chairman addressed the Section upon the faculty alleged 

 to be possessed by the animal of Oyprcea, of dissolving its shell 

 and forming a new one to meet the necessities of its growth ; 

 illustrating his remarks by specimens from the Museum. He 

 also showed that the spots upon the exterior surface of the shells 

 of some species of Cowries, which indicate the bases of the fila- 

 mentous growths upon the mantle, do not exist upon young 

 shells, and therefore it is probable that these growths do not 

 commence until the animal approaches maturity.
