Bathytoma is a genus of deep-water sea snails, marine gastropod mollusks in the family Borsoniidae.

[2] This genus is known in the fossil records from the Paleocene to the Quaternary (age range: 55.8 to 0.781 million years ago).

[3] This marine species occurs in the Eastern Indian Ocean (Madagascar, Mozambique, South Africa); off Indonesia, New Caledonia, Panglao Island, Sulu Sea, Vanuatu, Wallis and Futuna, Bohol, Kerala, New Zealand, Philippines, Sea of Japan; off Australia (New South Wales, Queensland, Victoria, Western Australia).

They are all known from deep waters from 100 m to about 1500 m, but usually at 200–700 m. The lines of specific distinction appear to be drawn narrowly in this genus and to depend chiefly upon sculpture.

The novelty appears intimately related to Bathytoma engonia (Watson, 1881) [4] differing by the sharper keel, more elevated tubercles and generally coarser sculpture.
