Stromboidea
Original Description of the genus Drepanocheilus by Meek, 1864, p. 35:
- "Shell like Aporrhais, but without a posterior canal extending up the spire, and having the lip produced into a single, usually scythe-shaped projection. This type, as well as the including genus Anchura, differ from the Jurassic genus Alaria, in never having the labial appendage developed during the growth of the shell, so as to be left behind the aperture as projecting spines on the body whorl or spire. It, however, probably includes some of the so-called Alaria."
Type species: Rostellaria americana Evans and Shumard, 1857 (= Drepanocheilus evansi Cossmann, 1904); by original designation, Maastrichtian (Late Cretaceous), Sage Creek, Nebraska, United States.
