Part II - State of New Jersey

GASTROPODAnumber not determined, very gradually cspanding with additionalgro\vth; apes and aperture unkno\rsn. T'olotion slightly convex het~r.centhe sutures, and ornamented by a band of small oblique nodes immediatelyhelow the suture; also by a series of largcr vertical folds whichextend across the esposed part of the volution, belo~rr the upper bandof nodes, and numbering something more than half as many to the volutionas the nodes above. There are also very tine spiral striae almosttoo fine to be seen without magnifying. The lincs of gro\vth are fine butdistinct, and take a broad s\\,ceping backxvard curve below the sutures."The dimensions of one of the most completc individuals observed, aspecimen not complete to the aperture and 1sit11 the apex of the shellmissing, are: height, 27 mm.; maximum diameter, 11 mm.; number ofvolutions showing 9, apical angle 23'. A specimen 18 mm. in length,with the apex nearly complete has nine volutions. (\TThitfield)1Zernnrk.s.-The internal casts are rather loose-coile~l, with low,somewhat indistinct vertical nodes, but not retaining any indication ofthe narrow, nodose, revolving band seen at the upper margin of thevolution on the external surface of the shell. Good impressions of thcesterior of the shell are sometimes met with, and it is upon casts takenfrom such natural moulds that the external characters of the shell arebest shown. The form of the aperture of the shell has not been observed,so that the generic relations of the shell cannot he deter~nined with certainty; it seems likely, holvever, that it is not a true Cerifhiio~~.

(USGS19014). Sl~ell sn~all with turreted spire of medium height, spiral angleabout 26'. l'rotoconch not preserved. \Vhorls 5 or 6, closely appressed,suture deeply impressed. Body whorl with three strong, narro\r7 spiralribs above the periphery, a weak spiral at the periphery, follo~~~c~l belowon the base by a strong bifid spiral, a simple spiral of medium strength,and a \peak spiral at the lowest part shown in the cast. The peripheryis rounded and the base steep. The three strong ribs on the body whorlabove the periphery continue well developed rearvard on the flanks ofthe earlier whorls; the lower one is the largest, the middle one is ofmedium strength, and the upper one is the weakest.
