 This is one of our most common marine productions, so that, on 

 many parts of the coast, scai'ce a shell or stone can be dredged from 

 the deep that does not serve as a support to one or more specimens. 

 It appears often in the form of a mere crust about the eighth of an 

 inch in thickness when removed from the sea and in a state of con- 

 striction, but more commonly it rises \ip in conoid masses of vari- 

 ous sizes and lobed in a very irregular manner. Sometimes the 

 polypidom is a simple obtuse process, very much resembling the 

 teat of a cow's udder, whence our fishermen have happily named it
