APPENDIX C 205Sca~~tbula w~dnlcri diRers from S. perplana Conrad from the Cretaceousof Nen. Jersey mainly by its much coarser sculpture, and by itssmaller size.Dimensions: Lengtli 4 mm.; width 5 mm.; thickness 0.5 mm. (holotype).Locality: Boring 8 (694 feet) \\'OODBURIr formation.Holotypc: ANSP 30750.Named in honor of Kcmble Widmer, State Geologist of Nem Jersey.Cyclorisma jerseyensis Richards n. sp.Plate 93, Figures 21, 22Shell small, subtriangular, posterior end slightly attenuate; tectllnot well preserved, bnt similar to those of Cyclorisnra alta (Conrad)Surface ornamented with fairly prominent irregularly spaced ribs wit11wider interspaces; faint concentric lines between the ribs, and finerradial striations.Cyclori.snaa jerseyensis differs from C. nlta (Conrad) of the BlsekCreek formation of Korth Carolina by its coarser sculpture, and bybeing more elongate than C. dta ml~ich is almost circular.Dinlonsions: Length 4.5 mm. ; width 5.3 mm. ; thickness I .2 mm.Locality: Boring 16 (1648 feet) RtlRITAN formation.Holotype: ANSI' 30749.Linearia transcontinentalis Eichards n. sp.Plate 93, Figure 6Shell small, subelliptical in outline, depressed convex. Anterior andposterior margins both rounded ; basal post,erior margin convex. Bealznot clearly shown, but apparently small. Surface of the shell markedby fine concentric ribs and separated by depressed furrows about twoto three times the width of the ridges, also by radiating furrows whichcut through the eoneent,ric ridges. These are more conspicuous on t,hcmargins of the shell than in the ccnt,er, but are not nearly as prominent.as in L. mctastriata Conrad. The fnrrolr-s on the anterior part arefarther apart than upon the posterior portion of the shell and areslightly more conspic~~ons.Linenria transcontinentalis differs from I,. ntetastviata Conrad inthat its concentric ribs are coarser, the radiating lateral ridges are lessconspicuons, and the shell is less convex.Dimensions: Length 3.8 mm. ; width 5.5 mm. (holotype).Localit!/: Core 16 (1648 feet,) RARITAN formation.Ilolotype: ANSP 30456. - -.NEW JERSEY GEOLOGICAL SURVEY
