Thyreus Snail (Ariophanta thyreus)
The Thyreus Snail was described in 1852; it was known from several places in the Nilgiri Mountains in southern India.
The shells on average reach sizes of about 3,5 cm in diameter; they are of a horny brown color and often have a narrow dark rufous band below the subangulate periphery.
The species is now considered possibly extinct. [1]
