Siphonochelus (Laevityphis)
Taxonomy
Laevityphis was named by Cossmann (1903) [Sepkoski's age data: T Eo-l T Plio-u Sepkoski's reference number: 899]. Its type is Typhis muticus.
It was reranked as Typhis (Laevityphis) by Woodring (1959) and Dey (1961); it was reranked as Siphonochelus (Laevityphis) by Gertman (1969), Perrilliat (1992) and Todd (2001).
It was assigned to Typhis by Woodring (1959) and Dey (1961); to Muricinae by Squires (1984); to Siphonochelus by Gertman (1969), Perrilliat (1992) and Todd (2001); to Neogastropoda by Sepkoski (2002); and to Muricidae by Darragh (2017).
