Stromboidea

• Rimellidae
  • Ectinochilus
    • Ectinochilus gaudichaudi (d'Orbigny, 1842)

Types: A thorough search through the collections in Paris did not reveal any possible type material. The type material must therefore be considered lost. (Griffin & Nielsen, 2008)

Ectinochilus cf. gaudichaudi (d'Orbigny, 1842); late Eocene; Southern Peru; Coll. Tom DeVries; Copyright Tom DeVries

Comments

• This species is known from late Eocene sediments of northern Peru (Olsson, 1928) and southern Peru (DeVries, 2004).
• Since the siphonal canal has never been observed completely preserved, the generic assignment remains tentative (DeVries, 2004).
