Two specimens cannot be cate- gorized, a single larger spent individual ( mm) whose sex is indeterminate and a specimen ( mm) whose shell is too opaque to discern the soft parts within. Genus Prelametilo new genus Type species: Prelaiuctila claikci Allen and San- ders new species Hinge teeth composed of both elongate and taxodont types; adductor muscles un- equal in size; body occupying much of the mantle cavity; hindgut forming 4 loops on the right side of the body; the posterior end of the foot rounded. This genus differs from Lametila in the possession of taxodont teeth, more than two hindgut loops on the right side of the body, and by its hetero- myarian condition.
