This uniformly rich-brown species is remarkable for the six 
ribs which are continuous up the spire, and the three lirations 
which traverse each whorl. They are very prominent on the 
ribs, standing out like little transverse nodules, and are almost 
obsolete in the interspaces.

Under a simple lens the two apical whorls appear almost 
smooth; but by the aid of a more powerful microscope they 
are seen to be covered with numerous close spiral series of 
minute granules.

VI. The Genus Pemphix compared with the Genus Glyphea. 
In the preceding pages we have glanced at the organization 
of Pemphix Sueurt, Meyer, we have given a short historical 
sketch of the genus Glyphea, followed by a description of the
