External Appearance

(from Coe, W. R. (1901). Papers from the Harriman Alaska Expedition. XX. The nemerteans.. Proc. Wash. Acad. Sci.. 1-110.)

The dorsal surface is deep ochre yellow, sometimes inclining to orange, and sometimes to brownish, and thickly strewn with minute irregular dark red spots. The reddish markings are most conspicuous near the anterior end of the body, and in the dorsal, median line. In many places a large number of the reddish dots become confluent, and form an irregular patch of deeper color. These patches communal occur as broken longitudinal lines. Such lines are most abundant in the middle of the dorsal surface where they form a median longitudinal band of reddish-brown. The ventral surface is paler and the reddish markings are wanting. Along the median line the color is brighter yellow than elsewhere on the ventral surface. This is apparently due to the absence in this potion of the opaque intestinal lobes. The ventral surface often exhibits a greenish tinge to the yellow ground color. The posterior extremity is pointed and much paler than the rest of the body.
