often submit to the usual anesthetization and preservation without 

 shedding more than a few scales, but an apparently beautifully pre- 

 served specimen would subsequently be found without a single ad- 

 herent scale. 



Eunoe oerstedi Malmgren was taken at Eluitkak Pass and at no, 

 175, 216, and 453 feet. Gattyana ciliata Moore was taken at 522, 453, 

 118, and 138 feet. The abundant tan to brownish Gattyana cirrosa 

 (Pallas) was taken at Eluitkak Pass and at depths of no to 741 feet, 

 with from i to 18 individuals per haul. Two were taken through the 

 ice on February 18, 1950, at 162 feet. Three specimens were para- 

 sitized by HerpyUohins arcticus. G. cirrosa is new to Arctic Alaska. 



One of the most abundant polychaetes in the dredge hauls was 

 Harmothoe extenuata (Grube), which was taken at Eluitkak Pass 

 and at depths of 125 to 741 feet. Specimens up to 70 mm. in length 

 were taken, sometimes more than 50 per haul, but not all the speci- 

 mens could be saved. They were found among bryozoans and hy- 

 droids, on rocks, and among masses of worm tubes, and were fre- 

 quently hidden among the laminate growths of such bryozoans as 

 Bidenkapia spitshergensis. Each of two specimens from 217 and 

 125 feet had a female Herpyllohins arcticus on its head and one from 

 130 feet (September 15, 1948) had two. This species is new to 

 Arctic Alaska. 



Probably the most abundant polychaete in the dredge hauls was 

 Harmothoe imbricata (Linnaeus), which was taken from Eluitkak 

 Pass and in hauls from 70 to 741 feet. It seemed to be everywhere — 

 among barnacles, bryozoans, old holdfasts of hydroids and tunicates, 

 and around the bases of the octocoral Eimephthya rubiformis. There 

 is great color variation in this species, the general effect being gray, 

 but tan specimens and almost black ones are not uncommon. The 

 scales were usually mottled with brown, black, or red, but the most 

 distinctive pattern was one in which the black pigment was concen- 

 trated toward the inner half of the scales, producing the effect of a 

 black stripe down the center of the back. Five specimens from Eluit- 

 kak Pass on August 6, 1948, were parasitized by 3 to 9 specimens of 

 Herpyllobius arcticus. The one with the 9 copepods was only 38 mm. 

 in length. This species is new to Arctic Alaska. 



Most striking in appearance among the polynoids was Melaenis 

 loveni Malmgren with its small elytra which leave the center one- 

 third of the back bare. About three elytra on one side and two on 

 the other are black, the remainder of the scales and the body of the 

 worm being pale gray. Only two specimens were dredged (from 

 gravel bottom at a depth of about 10 feet) but they were common on
