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:[1]
Greatest transverse breadth 0.7 inch. At the first glance this shell would probably be mistaken for the last described species, from which it differs more especially in the greater proportionate size of
the aperture, in the perfect parallelism of the inner lip with the axis of the shell, its denticulation nearly throughout its whole length, instead of merely in the centre ; in the compression of the whorl at the back of the callus, and its subcentrical position, thereby occasioning the approach of the shell to a symmetrical configuration, and finally in its suite of colours. It is much less frequent than N. depressa. I have met with only two specimens, in the Hugli at Fort William, and in Tolly's Nullah, adhering to piles and bricks. The aperture is livid white, with blackish shades. The operculum, following the form
of the aperture, is broader than in N. depressa, and its two costate teeth are more developed.
The color of the live snail is black or dark grayish with black outline.[8]
The color of the shell is dark brown.[8] The coloration has also purplish and greenish spiral bands.[8] Algae or silt are on periostracum usually.[8]
The width of the shell is 10–13 mm in India,[8] 7.2-12.9 mm in Hong Kong,[6] and 6–17 mm in Singapore.[7] The height of the shell is 4.5-9.2 mm in Hong Kong.[6] The length of the shell is 13-19.6 mm in India,[8] up to 17.4 mm in Hong Kong,[6] and 9–24 mm in Singapore.[7]
The operculum has paucispiral nucleus with a small initial region.[11]
The Radula was described and depicted by Huang in 1997.[6]
Neripteron cornucopia lives in intertidalmangroves.[8] For example, Blanford collected them on stems of nipa palm Nypa fruticans.[10] It lives in water on various substrates: on mud, on fallen leaves, on stones and under stones, on concrete.[7]
