ABSTRACT
A comparative study of juvenile shells of Rapana thomassiana Crosse, 1861 from the coasts of Bulgaria (42 specimens) and Georgia (5 specimens) has shown their morphologic and biometrical distinctness. The young specimens from Bulgaria were markedly different from the adults (10 specimens). The studied shells are described considering their colour variability, regeneration, eplzoites, and anomalies (3 anomalous shells).
