Amastra (Cyclamastra) morticina Hyatt & Pilsbry, 1911 alternative representation Amastra morticina is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Amastridae.

The body whorl is inflated at the periphery and base, with weak plications near the suture, giving it an irregular appearance.

The deep umbilicus is bordered by an obtuse angle and contains a distinct spiral gutter within.

The aperture is small, angular at the upper end, and subangular at the base of the columella.

A small, oblique columellar lamella completes the shell's delicate structure.
