secreted mucous bags about themselves. This species has been known 

 only from the type specimen from Bering Strait and later from Japan. 

 These Point Barrow nemerteans have added to the knowledge of 

 circumpolar distribution. Coe (1952) states: "Even at the present 

 time no nemerteans are known from the Polar seas between the 

 Point Barrow area and northwest Greenland on the east and Novaya 

 Zemlya and Franz Josef Land on the west." 



Phylum SIPUNCULOIDEA 



Two or three species of sipunculids were collected, the most abun- 

 dant being Golfingia margaritacea (Sars), which occurred at Eluitkak 

 Pass and at nearly every station from 120 feet to 741 feet. From i 

 to II specimens were taken in each haul. They were found among 

 masses of barnacles, in the interstices among pebbles and gravel that 

 covered the tunicate Molgula, and among debris gathered around old 

 holdfasts of tunicates and hydroids. The Point Barrow specimens 

 extend the range of this species from the 54th parallel of latitude into 

 the western Arctic to the 71st parallel. 



A single individual of a species of PhascoHon was dredged from 

 741 feet, and although it may well be new it was too small and con- 

 tracted for anatomical study. 



The sipunculids were identified by the late Dr. W. K. Fisher. 



Phylum PRIAPULOIDEA 



Two species of this phylum were found ; the better known of the 

 two was taken less frequently than the rare one. One specimen of 

 Priapulus caudatus Lamarck was dredged from 741 feet and another 

 was taken through the ice on February 18, 1950, from 162 feet. Four 

 other individuals, ranging in length from 70 to no mm. were washed 

 ashore. These specimens extended the range of this species into the 

 western Arctic. 



A single small specimen of Halicryptus spinulosus von Siebold was 

 dredged at Eluitkak Pass on August i, 1950, and 17 specimens, rang- 

 ing in length from 70 to 170 mm., that washed ashore were collected. 

 Only small examples of this species had been taken previously, the 

 largest, recorded by Theel from Spitsbergen, being 27 mm. in length. 

 This species has been recorded from West Greenland on the east and 

 from the Kara Sea on the west but had never before been taken from 

 the North American Continent. 



The writer is indebted to the late Dr. W. K. Fisher for identifying 

 these species and for furnishing other data.
