A previously unknown character state of the highly polymorphic shell of Archachatina churchilliana (Melvill & Ponsonby, 1895) is recorded, possibly indicating that all uniform yellow shells of this species, hitherto discussed, are not fully grown. The previously unknown genital anatomy of Achatina natalensis Pfeiffer, 1854, is described, indicating that it should be transferred to a different genus and subgenus.
