86 The {Williams Collection of Shells 



supplemented by a small series of recent Brachiopods 

 representing about a dozen genera and twenty species. 



Magnificent and almost numberless as are the 

 Ocean treasures in this collection there are in almost 

 every family of the thousands of Land shells exhibited 

 many of the rarest specimens known, as well as many 

 of those which are most beautiful. The same may be 

 said of the Bivalves and Fresh- water shells.
