COE: NEMERTEANS OF WEST AND NORTHWEST COASTS. Ill 



in the Albatross collections by a portion of one individual about 

 30 cm. in length from Beaver Harbor, B. C. The species has been 

 previously recorded from Puget Sound and from Sitka, Alaska 

 (Griffin, '98), and from Sitka, Prince William Sound, Dutch Harbor, 

 and Unalaska Island, Alaska (Coe, :01). Its known range is there- 

 fore fi'om Monterey Bay, California, to Puget Sound, along the 

 coast of Alaska to the Aleutian Islands — a distance of about 2600 

 miles. It occurs under stones, among sea- weeds, and in crevices of 

 rocks, but in none of the localities mentioned is it a common species.

The species is characterized by its deep brown color an<l number 

 and arrangement of its narrow, white transverse and longitudinal 

 hnes. There are five distinct, parallel longitudinal lines and an 

 indication of a sixth on the median ventral surface. Of the five dis- 

 tinct fines, one lies on the dorso-median surface, while the other 

 four are placed symmetrically on the lateral margins, the two on 

 each side being separated by an angle of about 45°. 



As illustrated by PI. 1, figs. 2, 3, the six longitudinal white lines 

 so characteristic of this species most commonly consist of rows of 

 minute isolated white dots, rather than continuous Hnes of color. 

 These dots may be so closely placed, hoMever, as to give the appear- 

 ance of continuous lines in one ])ortion of the body, and of rows of 

 dots in other portions. The distance separating the individual dots 

 is liable to the greatest variation, but the pattern is always constant. 

 Occasionally the median ventral line is quite conspicuous between 

 the second and fourth transverse rings, but is usually merely indi- 

 cated by a row of scattered white dots. 



A series of narrow white rings encircle the body at fairly regular 

 intervals throughout its whole length. There are often 150 or more
