External Appearance

(from 1943 Coe, W.R. Biology of the nemerteans of the Atlantic coast of North America.)

Usually pale olive green, greenish brown or reddish brown, darker on dorsal surface, particularly on head: frontal margin and lateral borders of head white or pale gray; brain region deep red: body sometimes encircled by several to 20 or more very narrow and inconspicuous rings of lighter color; also a fine longitudinal line of lighter color may be present on each lateral margin of body and in the mid-dorsal line. In some individuals (variety capistratus) the lighter rings may be represented on dorsal surface by distinct transverse bands of lighter color and the 3 longitudinal lines may be sharply demarcated.

Young worms and small regenerating individuals white to grayish, with rosy brain and a few small brown ocelli.
