Collection was realized dredging sea bottoms along the coasts of Apulia and through specimens exchange activities with other famous malacologists. The present work represents a first contribution to the restitution of the historical and documentary heritage named "Ecological Malacology Collection" by the Prof. P. Parenzan to the scientific community. Such a purpose has been pursued through photographic documentation, ordering and conservation renewal activities, but also through the realization of a digital catalogue and by a modernization of the taxonomical positioning of specimens which, by now, is limited to 1241 mono specific shell groups (on a total of 6794).
