CRETACEOUS FOSSILSClass GastropodsCalliornphalus oceanicus Richards n. sp.Plate 94, Figures 1, 2, 3Shell small, nacreous, rather depressed, typically troehoid in shapeand umbilieate; spire low; whorls four or five, rounded, sutnres impressed,circular in cross section ancl gradually increasing in size;protoconeh relatively flat. Sculpture of about 19 spiral noduloseribs; tubercles arranged in parallel axial rows which are crossed b,vfaint spiral-shaped ridges, giving a somewhat cancellate appearance tothe shell ; suture slightly impressed ; subsutural rib strong ; aperturesubcircular; umbilicus broad, umbilical heel tuberculate.Calliomphalas oceanicus differs from C. americanus Wade from thr:Ripley formation of Tennessee (Coon Creek) in that it has a lowerspire, and more strongly cancellate sculpture. C. oceaniclcs lacks theconspicuous nodes surrounding the umbilicus as in C. antericanus.Dimensions: Height 6.9 mm. ; width 9.5 mm. (holotype).Locality: Boring 16 (1648 feet) RARITAN formation.Halotype: ANSP 30438; also 8 paratypes, badly crushed.Named from Ocean County, New Jersey, in which the well was located.Tuba ( ?) fontis Richards n. sp.Plate 94, Figures 5, 6Shell of medium size, spiral but broacl at base, spire acute, whorlsseven, convex and circular in cross section increasing in size towardthe aperture; apical whorl very small. Sculpture consists of beadedspiral threads of unequal size, with two very eonspieuous rows on spiralwhorls, but with five or more on the body whorl; beaded etiect of threadsproduced by numerous narrow sharply elevated axial lines across thecrests of the spiral ridges. Suture distinctly impressed; aperture apparentlycircular; lip not distinct.Tuba ( 9 ) fo?~t&s differs from T. parabella Wade from the Ripleyformat~on at Coon Creek, Tennessee, by its less eonspieuons oruamentation,its fewer spiral ribs, and by having one less whorl. It is alsoconsiderably smaller than T. parabella. It is placed in the genus Tubacluestionably because the aperture and eolnmella are not clearly visible.It is much larger than 7'. (?) retiel~l(cta Johnson from the IVoodbnryformation of New Jersey and lacks the radial sculpture. Nanled fromthe Latin fons = well.D~menswns: Height 11.9 mm.; width 7.9 mm. (holotype).Locality: Boring 1 (862 feet) WOODBURY formation.Rolotype: ANSP 30755.NEW JERSEY GEOLOGICAL SURVEY
