SUMMARY
The original description: "Color whitish, but appearing deep green, due to dense chloroplasts in disgestive diverticua; cerata and body covered with scatterend large black round chromatophores; faint orange rings surround cerata near distal tip; bluish-green iridescent spots and small whitish glands scattered on cerata; a green iridescent spot, surrounded by a yellow ring, is located between the large eyes and the paricardium. Rhinophores long, cylindrical, tapering, with auriculate base; cerata pyriform (fusiform in relaxed animals), arranged in five to six diagonal rows on each side, four cerata per row; cerata separated from the foot by a shallow furrow. Posterior foot divided by transverse groove and containing digestive diverticula, appearing much like a ceras. Radular teeth uniform in size, about nine teeth in the ascending arc and 10-12 in the descending; ascus absent." (Clark, 1984, The Nautilus, 98(2), p. 92).
