Distribution

This species occurs in New Zealand.^[1] The opercula of species of Bolma are oval, circular or intermediate in shape. Almost nothing is known of the biology of species of Bolma although it is assumed that they have at least a short planktonic larval life and probably do not graze on attached algae because most species live well below the limits of algal growth.^[3]
