The vertical ribs upon the volutions ofthis species arc somelvhat different than is usual in the genus, they heingrounded, thickened ribs and not simply varieal lips, the rariz havingbeen filled to a solid rib before the growth of the shell had progressedbeyond it. The number of rarices varies somewhat in the differentvolutions. The finer markings of the shell are not ell prl:serveclin the specimens, but on one specimen they seen1 to consist of ~:loselgarrangedspiral lines."Range in Xew Jersey-MAGOTIIY: GNEW JERSEY GEOLOGICAL SURVEY
