Some species of Xerocrassa are instead considered to belong to the subgenus Xerocrassa, within the genus Trochoidea; in those cases the species are listed under the generic name Trochoidea. However, for other authors both taxa are not closely related being different genera.[3][4][5]

Taxonomy

The genus Xerocrassa is divided in 3 subgenera:[5]

  • Xerocrassa (Amandana) Fagot, 1891
  • Xerocrassa (Xeroclausa) Monterosato, 1892
  • Xerocrassa (Xerocrassa) Monterosato, 1892

Species
Xerocrassa cretica shell
Xerocrassa montserratensis shell
Xerocrassa penchinati shell
Xerocrassa prietoi shell

There are 53 or more species in the genus Xerocrassa:[6][7]

gollark: I have! I just didn't know `pcall` did this. It's so weird.
gollark: The hard part is making it *mostly* like an actual environment but denying access to some stuff.
gollark: There are still all kinds of side channel attacks, but eh.
gollark: Oh, if I just wanted to deny access to basically everything it would be *fairly* easy.
gollark: This is even crazier. If I return the whole environment table from `pcall` it's out-of-sandbox, but if I check the return value *in* the function it somehow breaks?
