Cryptogemma is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids. [1]
These are deep-sea species with a wide geographic distribution.
According to Zaccharias et al. (2020) this genus should only include:
The others should be excluded from this genus because the lack key characters such as the narrow fusiform shell and the well-marked peripheral anal sinus. They show closer resemblances to other conoidean families (such as Horaiclavidae) than to Turridae. [2]
