Cryptogemma is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids.
Distribution
These are deep-sea species with a wide geographic distribution.
Species
According to Zaccharias et al. (2020) this genus should only include:
- Cryptogemma aethiopica <small>(Thiele, 1925)</small>
- Cryptogemma periscelida <small>(Dall, 1889)</small>
- Cryptogemma phymatias <small>(Watson, 1886)</small>
- Cryptogemma powelli <small>Zaharias, Kantor, Fedosov, Criscione, Hallan, Kano, Bardin & Puillandre, 2020</small>
- Cryptogemma praesignis <small>(Smith, 1895)</small>
- Cryptogemma tessellata <small>(Powell, 1964)</small>
- Cryptogemma timorensis <small>(Tesch, 1915)</small>
- Cryptogemma unilineata <small>(Powell, 1964)</small>.
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.
Species within the genus Cryptogemma include (according to WoRMS):
- Cryptogemma aethiopica <small>(Thiele, 1925)</small>

- Cryptogemma chrysothemis <small>Dall, 1919</small>
- Cryptogemma cornea <small>(Okutani, 1966)</small>
