Description

''Neripteron cornucopia'' was originally described under the name ''Neritina cornucopia'' by William Henry Benson in 1836. Benson' original text (the type description) in Latin and English reads as follows: The color of the live snail is black or dark grayish with black outline. The color of the shell is dark brown. The coloration has also purplish and greenish spiral bands. Algae or silt are on

usually. The width of the shell is 10–13 mm in India, 7.2-12.9 mm in Hong Kong, and 6–17 mm in Singapore. The height of the shell is 4.5-9.2 mm in Hong Kong. The length of the shell is 13-19.6 mm in India, up to 17.4 mm in Hong Kong, and 9–24 mm in Singapore. The operculum has paucispiral nucleus with a small initial region.Kano Y. (2006). "Usefulness of the opercular nucleus for inferring early development in neritimorph gastropods". ''

Ecology

''Neripteron cornucopia'' lives in intertidal mangroves. For example, Blanford collected them on stems of nipa palm '' Nypa fruticans''. It lives in water on various substrates: on mud, on fallen leaves, on stones and under stones, on concrete.
