No specimen of this animal was preserved, but Captain King observes, that the animal he caught, of which he made a drawing, differed from Lesueur's figure of P.megalista, in being of smaller size, and with fewer tints; the colour of the tentacula was a brighter purple tipped with yellow globules, and the crest of a greenish hue, but the general colour of the animal was purple.

It measured from three-quarters to one inch in length.
Captain King considered it to be a variety of P.megalista.
Porpita gigantea.
