BuLiMUs ELOBATUS. Testa solidula, elongato-ovata, longitu- 

 dinaliter plicoso-striata et lineolis volventibus interruptis corrosa, 

 epidermide sordide luteo et viridi marmorata induta, arete um- 

 bilicata : spira anfr. 5 convexis, ultimo magno : apertura angus- 

 ta, sub-elliptica ; labro simplici, obtuso, aurantio; plica columel-

Belongs to the same group as B. fulguratus and B. malleatus., 

 characterized by the large fold on the columella. It is the 

 largest of the three, resembling the former in its sculpture and 

 the coloring of the aperture, and the latter in coloring. It is 

 distinguished by its unreflected lip, its narrow aperture, less con- 

 spicuous and more oblique columellar fold, more ventricose and 

 less oblique whorls. 



BuLiMus MOROSus. Tcsta crassa, rudis, ovata, albido-cinerea, 

 longitudinaliter striata, arete umbilicata ; spira anfr. 5 convexis : 

 apertura subauriculata ; peristomate latissime revoluto, albo, 

 postice angulato ; plica columellari ampla.Long. If, lat. 1 poll. 

 Hah. Feejee Islands. 



Of the same group as the preceding, but is smaller, more solid 

 and less elegant than its associates. Its want of epidermis and 

 colors, its angular outline and very broad, revolute lip, character- 

 ize it.
