NEMERTEANS 20I 



dredged at several localities off San Pedro in 2 to 20 fms. In these 

 individuals the coloring of the body, and the extent of the white ter- 

 minal border on head were somewhat different from that described for 

 the specimen from Alaska. The rather small mouth with its grayish 

 lips was situated some little distance posterior to the white terminal 

 border of head, and as far back as the posterior ends of the cephalic 

 furrows. 



Color of body was usually very dark, smoky brown, with a tinge of 

 purple, but was sometimes almost black. A more reddish median 

 line was indicated only when body was much extended. Lateral 

 margins were not pale. Both dorsal and ventral surface of head pure 

 white for about three-fourths the distance to posterior ends of cephalic 

 furrows. Proboscis pinkish in color. 



A single specimen belonging to this species was dredged in 50 fms. 

 between San Pedro and Santa Catalina Island, Calif. This specimen 

 was jet black in color except on the head, which had the characteristic 

 white cephalic border exactly as here described. 



The species has previously been recorded only from Sitka, Alaska 

 (p. 85 of previous article), where a single specimen was found under 

 a stone at low water. It is not uncommon in mud between tides in 

 San Pedro Harbor, Calif.
