80 CRETACEOUS FOSSILSthe outer volution; just below this ridge is a narrow, concave hand,outside of which, upon the shoulder of the volution, is a series of strongrounded nodes about three mm. apart from center to center on theouter volution, which continue longitudinally as strong, rounded ribsto the anterior extremity of the shell. Surface also marked by fine, verticallines of growth; revolving lines entirely absent. The internaleast is similar in general form, the suture is well defined, the volutionsare flattened above, or even slightly concave, towards the aperture,sloping downward to the line of maximum diameter beneath the rowof strong nodes on the exterior, helorv which the sides are nearly verticalto the suture below, or in the body volntion becoming concave towardsthe anterior extremity. The vertical ribs are shown on the internalcasts, but are much weaker than upon the exterior of the shell."(lTTeller)Remarks.-"This species is based upon a natural mould of the exteriorof the shell with the internal east of the same individual. It isone of the few individuaIs of this genus from the Cretaceous formationsof New Jersey whose external characters are known to any eonsiderabledegree."
