Crommium

Gastropoda - Naticidae

Taxonomy

Crommium was named by Cossmann (1888) [Sepkoski's age data: K u T Mi Sepkoski's reference number: 614]. Its type is Ampullaria willemettii.

It was reranked as Ampullina (Crommium) by Nagao (1928), Traub (1938) and Turner (1938); it was reranked as Amaurellina (Crommium) by Pacaud and Le Renard (1995).

It was assigned to Ampullina by Nagao (1928), Traub (1938) and Turner (1938); to Globulariinae by Givens and Kennedy (1976); to Ampullospiridae by Iqbal (1973) and Adegoke (1977); to Amaurellina by Pacaud and Le Renard (1995); to Naticidae by Squires (1999); to Neotaenioglossa by Sepkoski (2002); and to Ampullospirinae by Harris and Palmer (1947), Marincovich (1977), Squires (1987), Majima (1989) and Perrilliat et al. (2006).
