Thick Partulina Snail (Partulina crassa)
The Thick Partulina Snail was described in 1853, it was apparently restricted to a place named Kohele on the Hawaiian island of Lana’i, a place that now is so to say completely overgrown with foreign, invasive vegetation.
The shells of this rather large species reached sizes of 1,8 to 2,2 cm in heigth. [1]
