Pelicaria Rugosa

Stromboidea


Original Description of Struthiolaria rugosa by Marwick, 1924, p. 189:

  • "Shell ovate, spire about same height as aperture; whorls 6, convex; sculpture, spire-whorls with 56 strong cords with narrow interstices, lowest cord being wide and having secondary spirals on it and on wide interspace below it, body-whorl with 15 equal cords, with interstices of almost same width and generally containing fine secondary spiral, growth-lines very strong over whole shell, giving spiral cords a moniliform appearance; aperture ovate, channelled above, with very short wide canal below; outer lip thickened, reflexed, bisinuous; inner lip with strong regular callus equal in width to outer lip; columella concave, strongly bent to right below."

Locus typicus: Patea, South Taranaki District, North Island, New Zealand

Comment Marwick, 1924, p. 189:

  • "As stated on page 179, this shell was Hutton's plesiotype of S. cingulata Zittel. This mistake arose from Zittel's figure representing a specimen with unusually convex whorls; but the characteristics features, obsolete bicarination of the body-whorl, and the disposition of the inner lip-callus show that S. cingulata belongs to the papulosa group, whereas there can be no doubt that this specimen falls under the vermis group. In outline it is very near S. convexa, but is easily distinguished by the strong spiral cords, which are rendered moniliform by the prominent growth-lines."
