Fanulena perrugosa Iredale

Rugose Fanulena Snail (Fanulena perrugosa)

This species was described in 1945, apparently based on two subfossil shells; it was restricted to Norfolk Island.

Shell small, tall, elevated, recalling imitatrix [Fanulena imitatrix (Sykes)], with the apical whorls apparently smooth; the other whorls rounded, prominently ribbed, about twenty ribs seen on face, base rounded, periphery subkeeled, columella slightly thickened, not toothed. Breath, 3.75.; height, 4 mm.

The species was apparently never found alive and is clearly extinct.
