External Appearance

(from Coe, W. R. (1905). Nemerteans of the west and northwest coasts of America.. Bull. Mus. comp. Zool. Harv.. 1-318)
Dark brown, with very numerous fine white rings encircling the body at irregular intervals throughout its whole length. Some of the rings are very much finer than others, and many are more or less broken and incomplete. A large specimen has several hundred of these rings, which remain sharp and conspicuous after the worms have been kept in alcohol for many years. Snout bordered laterally and anteriorly by narrow horizontal white band, which passes through or immediately above terminal proboscis pore and joins the first white ring, which occurs at junction of snout to posterior portion of head. White rings commonly 1 mm or less in breadth, while alternating brown bands arc about 3 mm wide in moderate extension, but are considerably narrower than diameter of body.
