Catalog entries: Liriospyris ovalis
type image: L. ovalisOriginal description: Diagnosis: A species of Liriospyris characterized by a smooth lattice shell that surrounds the front and back of the sagittal ring and two broad lattice bars that are joined to the apex of the sagittal ring and parallel to the lateral axis.
Description: Sagittal ring D-shaped; 37 to 57μ high; 37 to 53μ thick; joined directly to apex and base of lattice shell. Except for short vertical spine arising from midpoint of sagittal ring, sagittal-ring spines are lacking. Single pair of connector bars project from proximal end of vertical spine. Lattice shell smooth; 56 to 105μ wide; 84 to 116μ thick; surrounds front and back of sagittal ring; not constricted sagittally and does not extend below base of sagittal ring; appears as thin sheet perforated by circular, densely spaced latticepores 1 to 5μ in diameter. Lattice bars are of two widths. Narrow lattice bars are arranged without apparent uniformity, whereas five broad lattice bars are joined to sagittal ring at regular positions. Four broad lattice bars are oriented parallel to the lateral axis; two are joined to front and back of apex of sagittal ring, and two to front and back of base of sagittal ring. One broad lattice bar is parallel to horizontal axis and joined to front-apex of sagittal ring. Primary-lateral processes joined to middle of base of sagittal ring and taper distally to simple points. Two broad-lattice bars, joined to the front and back of the base of the sagittal ring, converge laterally and are joined to form a ring. In some specimens, the apical broad-lattice bars are joined laterally; in other skeletons, the outlines of these broad-lattice bars becomes diffuse distally. No frontal, sternal, or vertical pores.
