Drepanocheilus Herberti

Stromboidea


Original description of Drepanocheilus herberti by Kiel & Bandel, 2002:

  • "The shell comprises nine whorls and has an upward turned, dagger-like wing. The early teleoconch whorls show axial and spiral lines. The last three whorls bear a strong keel in the lower third, have straight sides, and appear angular. The keel continues onto the wing where it corresponds with a groove on the inner side of the wing. There are two more keels present on the body whorl which terminate at the wing. The aperture has lenticular shape and is slightly convex. The posterior spur of the outer lip is attached to the spire and may continue for a distance of up to four whorls. The holotype is 11 mm high, 11 mm wide and has an apical angle of 30."
