In the second part of the note a discussion is given dealing with the importance of different characters in the systematics of the genus Bathynella Vejdovsky and with species individualisation in the sub-genus Bathynella (Bathynella) Vejdovsky. We emphasize the differentiation of some elements of the VIIIth male pereiopodes, these appendages never having the same morphology in different species. Taking into account the structure of the apical end of the pennian anterior plates, we suggest to group separately boteai with vaducrisensis and plesai with ruffoi. The main conclusions of the recent studies on the European Bathynella are also given.
