The second part of this series on the Bulimulidae deals with the genera Plekocheilus Guilding and Naesiotus Albers, two and six species of which are recognized respectively. The following new synonymy is proposed: Bulimulus chrysaloides Pilsbry = Naesiotus chrysalis (Pfeiffer). Bulimulus (Protoglyptus) sanctaeluciae var. luciae Pilsbry is considered to be a valid species.
