Outer volutionregularly rounding from the suture to the base of the anteriorcanal, marl;e(l by eight or nine spiral ribs, one of which on the upperside, about half way bet\'cen the periphery and the suture, is slightlynodose, the strongest costae are those upon and just below the periphery;on the upper side, bctrvecn the nodose rib and the suture, is asingle faint rib. On the internal cast the revolving ribs are much fainterthan upon the sllcll itself; and the nodes of the uppermost costa arenot shown."

The volutions distinctly flattened above in a spiral bandjust below the suture, the outer margin of the flattened band beingelevated in a moderately strong revolving rib, below this rib the outerrolution is nearly regularly conves to the base of the anterior canalwhich is rather elongate and slender; surface of the outer volutionmarked by about six or seven strong, relrolving ribs bet,ween the outermargin of the flattened band above and t.he base of the anterior beak,the outer half of the volution being also marked by several, ratherstrong, vertical rarices which are about twice as far apart as the revolvingribs, these varices do not cross the flattened band above, and attheir junction with the revolving ribs they are elevated into roundedNEW JERSEY GEOLOGICAL SURVEY
