[3][4][2] Cominella is a genus of medium-sized buccinoid marine snails.

[7][8] Many extant species are endemic to coastal waters off of New Zealand[4][5][6] and Australia (including Norfolk Island).

[3][4][5][6][8] Ancestors of Cominella species in Australia likely migrated from New Zealand via long-distance egg rafting, despite taxa exhibiting direct development.
