Discussion. — A total of 67 species, 2 of which are new, are reported 

 herein from the Bering, Chukchi, and Beaufort Seas. The most 

 numerous species in the collection are: Pholoe minuta, Glycinde 

 wireni, Haploscolojdos elongatus, Cossura longocirrata, Tharyx multi- 

 Jilisf, Sternaspis scutata, Heteromastus Jiliformis, and Myriochele heeri. 

 The latter was the most frequently encountered species; it was particu- 

 larly common at some of the stations south and east of St. Lawrence 

 Island (see fig. 1). Principal associates with this tube-building 

 pol5'chaete were Pholoe minuta and Haploscoloplos elongatus, with 

 Glycinde wireni and Tharyx multifilis? present less frequently. 



In addition to the 2 new species encountered, new distributional 

 records were established for 12 species. The northern distribution 

 was extended for 8 species, namely, Arctonoe pulchra, Harmothoe 

 hartmanae, Typosyllis alternata, Micronephthys minuta, Haploscoloplos 

 elongatus, Spiophanes bombyx, Travisia breiris, and Rhodine bitorquata. 

 Four species are newly recorded from Alaskan waters: Naineris 

 quadricuspida, Skardaria jragmentata, Cossura longocirrata, and 

 Ophelia borealis. 



Data on the geographical and depth distribution have been included 

 for each species only when the information is new or not included in 

 Pettibone (1954).
