An albino shell of Nautilus is described. The shell is 174.5 mm in diameter with a whorl width at the aperture of 81.9 mm. It bears a black band at the aperture indicating that it is a mature animal. The morphology of the shell conforms to the general species description of Nautilus pompilius Linnaeus, 1758, in respects, except that it lacks any reddish-brown color strips. The lack of color stripes on the shell is interpreted as a case of albinism, although it is unknown if the soft parts also lacked color. This is the first reported case of an albino Nautilus although such shells have periodically cropped up over the years for sale on the internet.
