Palmadusta humphreyii, common name : Humphrey's cowrie, is a species of sea snail, a cowry, a marine gastropod mollusk in the family Cypraeidae, the cowries.

Spelling

The epithet humphreysii is an incorrect original spelling that was corrected by Gray himself in the errata page of the same volume of the Journal. See Petit (2012: 91):

"11. The species name humphreyii was on page 489, in error, as humphreysii. This was corrected by Gray on the Errata page [603] of the same volume of the Journal. This is a correct and valid emendation under I.C.Z.N. Article 32.5.1.1. The name with its original incorrect spelling is in current usage, the errata sheet evidently having been overlooked by Cypraea specialists. Iredale & McMichael (1962: 61) list “humphreyii (humphreysii errore)” but do not mention the errata page. Schilder & Schilder (1971: 122) attributed that usage to Iredale & McMichael and listed it as “published in a not valid way” in the synonymy of Palmadusta lutea humphreysii on page 52."

This action, therefore, restores the original correct spelling of humphreyii. (FM, 2015-02-27).

Description

These quite uncommon shells reach on average 10 - of length. The basic color and pattern of this species are quite variable.

The underside may be orange, pale yellow, pale brown or pale pink, with a narrow sinuous aperture and well-developed teeth. In the living cowries the mantle is bright red, the mantle and the foot are well developed, with short papillae and external antennae.
