* The genus Paterina, representing, according to our present knowledge, the fundamental 
stock or radicle of all the Brachiopods, might be embraced by some of the primitire families, 
both of the Inarticulata aud the Articulata. By placing it, inthis arrangement, outside both of 
the great sub-classes, it is the pu: pose to express the fact that the genus belongs as much to 
one as to the other, and that it is actually beyond the pale of both asit has not assumed the 
differential characters of either.
