---CRETACEOUS FOSSILSDescription.-"Shell <strong>of</strong> medium size, short-fusiform, nearly twiceas long below as above the periphery <strong>of</strong> the last volution when viewedfrom in front, and almost regularly sloping from that point to thepointed anterior extremity, as seen in the cast; apical angle about 50'or 55' ; volutions about four; subangular on the periphery and markedby moderately distant hut distinct vertical folds, which are obsoleteon the lower third <strong>of</strong> the volution, but increase in strength and distancewith the increased growth <strong>of</strong> the shell. Twelve <strong>of</strong> these folds can becounted on the body whorl <strong>of</strong> the best preserved cast. Umbilical cavityin the cast, as left by the removal <strong>of</strong> the columella, large and destitute<strong>of</strong> markings or folds <strong>of</strong> any kind; aperture cuneate-elliptical, sharplypointed below and angular above; surface characters <strong>of</strong> the shell unknown."(Whitfield)Remarks.-Weller erred in believing that the specimens describedby Whitfield as P. cuneus were young individuals <strong>of</strong> P. mullicaensk.Ranoe "~ in <strong>New</strong>t .7arseu-MT.

Volutions four and a half to five in number,ventricose, the upper ones rounded on the exposed parts, even in thecast, with distinct, deeply marked sutures; body volution somewhatshouldered on the top, but not flattened ; belolxr it is short and very rapidlydiminishing, so as to produce nearly a straight line from just belowthe point <strong>of</strong> greatest diameter to the margin <strong>of</strong> the cavity left by theremoval <strong>of</strong> the columella or axis <strong>of</strong> the shell; aperture imperfect inform, but as seen by the section <strong>of</strong> the cast must have been acutelyovate, sharply pointed below and gradually widened upward for abouttwo-thirds <strong>of</strong> its length, and rounded at the upper end; columella, asshown by the axial cavity, large and smooth, without folds or ridges;surface marked by numerous vertical folds, about eight <strong>of</strong> which maybe counted on the outer half <strong>of</strong> the body whorl ; these not seen on thecast below the point <strong>of</strong> greatest diameter, indicating their absence onthe lower part <strong>of</strong> the volution in the living shell; no remains <strong>of</strong> spirallines preserved on the specimen."
