Zoological Illustrations Series II/Plate 123



The figures on this plate complete the illustration of our monograph of this pretty and interesting group of shells. At present, we feel undecided whether this is a species, or a variety of A. bulimoïdes, from which it differs in being reversed, in having the marginal groove very distinct, instead of scarcely perceptible, and in colour. We possess only two specimens which came, with all the others, from the Pacific Islands.

This species is the most lengthened in form, and the most beautiful in colour of all those we have yet seen: some individuals, however, are more ventricose than others and the colours are no less variable. The ground colour is usually of a rich and deep chesnut, with from one to three bands of orange yellow, fulvous, or white; we have figured a further variety of a rich golden yellow with a chesnut line only at its suture: but in all these the marginal groove is very close and distinct.
