ODP Site 1050-264.JPGTaxonomy
holotype: T. primulaOriginal description: Test low trochospiral, built of about 16 nearly spherical chambers arranged in 2.5 to 3 whorls. Umbilicus is wide. Six to eight chambers in the last whorl, which enlarge relatively slowly and gradually in size. Sutures are radial and depressed on spiral and umbilical sides. Test surface slightly rugose. Cardinal aperture relatively large, in umbilical-extraumbilical position, and with strongly developed lip, which extends as a lobe into the umbilicus, covering a large part of it. Secondary apertures of the older chambers umbilical, in the last two or three sutural; they too possess more or less strongly developed lips, which may extend into the umbilicus.
Entries in the Catalog of original descriptions: Ticinella primula, Ticinella caronae, Ticinella floresae, Ticinella petalloidea

Rob, the character matrix and taxonomic discussion have been updated for this and other ticinellids, thank you for notifying us of this discrepancy.
The character matrix describes the wall texture as "smooth". Both the original description, and most of the illustrated specimens, show an ornamented (?pustule) wall texture.
