This is one of our most common marine productions, so that, on 
many parts of the coast, scarce 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 up 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 
Cow s-paps : other polypidoms are more or less divided into finger- 
like lobes, and assume figures that have suggested the names of Bead 
Mans toes or Bead Mans hands The outer skin is tough and 
coriaceous, studded all over with stellate figures which, if attentively
