* ''
Cryptogemma periscelida''
(Dall, 1889)
* ''
Cryptogemma phymatias''

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.
