GAYTIIOI'ODA 25Il'arritell~~ cf. jerseye?isis Richards, 1943, p. 30.Descriptioi~.-The dimensions of the type specimen, a nearly eompleteinternal cast, are: height, 38 inm.; rnasirnr~tn diameter, 9 mm.;apical angle about 16'; number of volutions present, 9. In the cast thesides of the sl~ell from the apex to the largest volut,ion are slight,ly eonyes,the divergence of the sides decreasing as the shell increases inlength. The suture in the east is close between the apical volutions, becomingbroader and more open as it approaches the aperture; the snrfaceof the \.olntions is smooth, flattenctl or slightly convex in the centralportion, ant1 curving more abruptly into the sntnre. Estcmally, assl~olvn by a east from the natural mould, the suture is slightly impressedin a narrow angular groove, the surface of the rolutions is flat andmarked by about five rt~ther broad, low, revolving rihs, of \vl~iall thelo\vest one is t.l~c st,ronger, two faint revolving ribs can also be clctcctcclnl:al. the periphery on the lolver surface of the last volution. (\\'cllcr)Rel,~nrks.-"\Veller referred some specimens of Tlrrritelln from aslab obtained from Sayre t~nd Fisher I'its qnestionahly to I?. jerseyensis\\'cller xvhich l~e 11ad clcscribed from the Cliffv.ood cli~j. of Xelv ,Tersey.hI;~terial collected more recently rcse~nhles the Tioritella of Weller'sslab and can also he rcfcrred q~~cstional~ly to T. ,ier.scgensis.
