Contribution to the Knowledge of Indian Marine Molluscs with a Note on the National Zoological Collections from Other Countries: Family-Turritellidae

In this paper, we have made an attempt to update knowledge on marine molluscs of India of various individual families and to compile the collections present in NZC, both Indian and foreign specimens and presenting an account of the families with as much as details possible on them. This is the sixth in the series of our contributions, and the earlier five were done by Zoological Survey of Indian's malacologist on the families Mitridae (Subba Rao and Dey, 1984) and Donacidae (Subba Rao and Dey, 1986), Muricidae (Subba Rao and Surya Rao, 1993), Tellinidae (Dey, 2006), Terebridae (Venkitesan and Mukhopadhyay, 2011).
