They are very active in confinement and will crawl out ofuncovered dishes. The prostomium is broadlj^ rounded, with 3 tentacles and evertiblenuchal organs which appear when the animal is moving. There are two pairs of eyes,the outer ones larger than the inner. After preservation the body-pigment turns to abrownish purple which is darker in some indi\dduals than in others and in all cases isof a lighter tint ventrally than dorsally. In some cases in the preserved materialthis pigment completely obscures the eyes, whUe in others the smaller pair only areinvisible. It seems probable that this condition is responsible for confusion in theclassification of this and related species, some of which h
