Trochus (Ziziphinus) Coppingeri.

Shell thin, shortly conical, rather shining, and somewhat iridescent, owing to the thinness of the calcareous layer above the pearl, very pale olive on the body-whorl, becoming darker on the upper volutions and reddish at the apex, ornamented with a series of minute red dots at the upper part of the whorls, just beneath the suture, and a second series on an angle at the middle of them, with a third series around the periphery of the last volution, and some rather larger spots around the umbilical region. Whorls seven; the first three or four some­what convex, with three coarse spiral liræ. Antepenultimate whorl flat, sloping above, with an acute angle a little above the base, spirally lirated; liræ little raised, with the exception of that at the angle and one immediately beneath the suture, which is very prettily beaded. Penultimate like the preceding, but with the sculpture less pronounced and the angle nearer the middle. Last whorl still more feebly sculptured, the beading having become obsolete. It is biangulated at the middle, and the space between the two angles is flat, giving the shell a very angular aspect. Base a little convex, concentrically striated, white at the middle, with a conspicuous depression at the umbilical region, which is surrounded by three or four strong liræ. Lines of growth fine. Aperture oblique, irregu­larly pentagonal, smooth, and beautifully pearly. Columella arcuate above, obliquely straightish inferiorly. Height 13 millims., diam. max. 14, min. 12.

Hab. 36° 47' S. lat., 55° 17' W. long., 28 fms. Off the mouth of the Rio de la Plata.

This beautiful shell is very distinct in form and character from any other in the genus.”
