PUGET SOUND NEMERTEANS. 209 



This species very strikingly resembles E. gracilc Johnston. It 

 may be distinguished by its narrower head with sharply defined 

 color patterns and general darker hue of body. 



Habitat and Distribution. Taken on piles, on and under 

 stones at Port Townsend, Washington ; Fort Wrangle and Sitka, 

 Alaska. The type locality (Stimpson) is the bay of San Fran- 

 cisco. Its range, as so far determined, is then from San Fran- 

 cisco to Sitka. 



8. Emplectonema violaceum Burger, 1896. 



Eiuiemertes violacce Burger. 



In life this form secretes an enormous amount of slime in which 

 it lies coiled up in tangled knots. It was found next to impossi- 

 ble to straighten it out sufficiently for accurate measurement, 

 but its length was estimated to be at least 50 cms. Broken 

 fragments in alcohol measure over 30 cms. Shape extremely 

 flattened, ribbon-like. Head rounded in front, directly contin- 

 uous with body. Color varies somewhat, though a fairly con- 

 stant pattern is presented on dorsum, which is densely flecked 

 with purple or brown upon a pale yellowish brown ground color. 

 Ventral portion yellowish white. Eyes numerous. 



The Internal Anatomy agrees more or less closely with 

 Burger's ('96) description. It ''does not possess a powerfully 

 developed head gland. The cerebral organs are very small and 

 lie very far in front of the brain. Many small eyes are present. 

 The oesophagus opens into the rhynchodeum." Powerfully 

 developed integumentary glands are present throughout the 

 body. 



Habitat and Distribution. On piles about Port Townsend, 

 coiled in a tangled mass, and enveloped in its mucus. The 

 type specimens of Burger were obtained near Calbuco, on the 

 coast of Chile. Its range is thus quite extensive. 



The great amount and tenacity of the slime proves an 

 obstacle to its proper preservation, as a coagulation of the 

 slime apparently hinders the thorough penetration of the al- 

 cohol.
