Nassodonta insignis is a species of brackish water snail, with gills and an operculum,[2] a gastropod mollusk in the family Nassariidae.

Smith (1895) pointed out that the original locality indication of Nassodonta insignis was “Peiho river, China”, and stated that on the label accompanying the type is written “Peihoi, fresh water, Calvert, with genus Velorita”.

Smith further pointed out that the genus Velorita (Villorita cyprinoides, Gray, 1825) occurs only on the west side of the Indian Peninsula, in the neighbourhood of Cochin, and in the estuary of the river Kundapur, (where it is largely eaten by natives), and that it has never been found in China, and that “Peihoi” could be some small village on the Malabar coast.

Aperture moderately narrow, outerlip thickened but not strongly variced, interior with 4-5 denticles decreasing in size anteriorly.

Smith (1895) correctly transferred the species from the Buccinidae to the Nassariidae, based on the presence of multicuspidate rachidian tooth of radula.
