Species / Xenophora Tatei


Original Description of Xenophora (Tugurium) tatei by Harris, 1897, p. 254

  • "Shell trochiform, with moderately elevated spire ; whorls broad, seven in number, very small to commence with, but rapidly increasing in size; the surface of the whorls, as seen between the foreign fragments adhering (mostly in the vicinity of the suture), is irregularly, obliquely undulating and ornamented by closely-set wavy, roughly spiral lineations, which are crossed by more or less conspicuous growth-lines; the keel at the periphery of the last whorl is sharp and undulating; the under surface is concave, the depression being most marked near the keel, curved lines of growth are conspicuous; aperture subquadrate; outer margin thin, strongly curved, deeply concave, and much produced at the margin owing to the prolongation of the last whorl in that region; inner margin slightly thickened, the thin callosity spreading over as a plate or lining on the inner posterior surface of the aperture; umbilicus funnel-shaped, small."
