The present catalogue includes all the known species of marine mollusks from India of the classes Cephalopoda, Bivalvia and Scaphopoda; systematically placing them under appropriate genera and family. Due to lack of recent reversionary work on taxonomy of many of these groups, the placement of many species under different genera in some of the families is rather provisional. This work was mainly based on the literature records of the Indian Marine Molluscs, specimens present in the National Zoological Collections of Zoological Survey of India and the materials received in Mollusca section for identification from different part of the country. Classification in this work followed the classification of Vaught (1989). All the genera are placed as per the arrangement made by the author i.e. the type genus first and then all other genera by alphabetical order. The synonyms, the first reference followed by almost all the Indian references as much as possible along with the distribution and remarks of each species.

This annotated checklist will stimulate interest in understanding the diversity of Indian marine mollusks, and hope that the future workers will be benefited in enriching the knowledge of marine molluscan diversity.
