Perdicella ornata is a species of tropical, tree-living, air-breathing, land snails in the family Achatinellidae.

Perdicella ornata has a shiny, acutely pyramidal shell with six margined whorls[2] that reaches a height of approximately 1.48 cm.

[6] Its national status is N1,[6] indicating that it is in grave danger of extinction due to a small population and number of occurrences, a limited range, severe threats, and other aspects.

Threats to Hawaii's rare species of snail, Perdicella ornata, include over-collection, invasive predators such as Euglandina, Oxychilus, and rats.

[6]In order to preserve populations, stop habitat loss, and lessen the effects of climate stress, advocacy for conservation and awareness-building and its importance are crucial.
