36 CRETACEOUS FOSSILSlength. The outer lip of the aperture is produced and terminates in t\vounequal pointed proeesses--one directed forward and the otlier baekward.Surface of the shell marked by a rather strong, nodose, subangular,revolving keel at a little above the mid-height of the outer volution.Upon the expanded portion of the outer lip this keel curves upward tothe posterior process of the lip. Above and below the median keel thesurface is marked hy moderately broad, rather depressed revolving ribs,and by less conspicuous vertical markings. On the internal casts, inwhich condition only the species has been seen in New Jersey, the surfaceis marked in the younger individuals by more or less indistinct revolvingand vertical ribs, which evidently were obliterated by the internalthickening of the shell, since the larger individuals are all smooth.The aperture in the casts is narrowly subelliptical in outline, the outerside being a little more strongly curved than the inner. l'hc eolumellarcavity left in the casts is rather broad and is not marked by revolvingfolds. (Weller)Remarks.-New Jersey specimens have been observed only as internalcasts in which the apex and the outer lip of the aperture havebeen imperfectly preserved.Range in New Jersey-MERCHANTVILLE : 13, 15WOODBURY: 20MT.
