Remarks

Rolán & Fernández-Garcés (2008) suspected that Triphora dealbata (C.B. Adams, 1850) could be related to C. melanura (C.B. Adams, 1850) , both described from Jamaica. The lectotype of T. dealbata is broken, without apex (Clench & Turner 1950: pl. 38 fig. 3), but its teleoconch is equal to that of C. melanura . Because C. melanura has priority over T. dealbata , appearing at the top of the same page on which T. dealbata was described, T. dealbata is regarded as a junior synonym.
