known only from the Kara Sea, was dredged at no and 175 feet. 

 The more abundant S. uncigerus Gurjanova was taken from 60 to 

 477 feet. The highest yields (a total of 107 specimens) came from 

 125, 175, 184, and 216 feet (September 15, 1948) by breaking apart 

 such bryozoans as Bidenkapia spitzhergensis and Myriozoum sub- 

 gracile. The body of this amphipod is white and the large oval eyes 

 are dusty rose. The eye color is retained in preservative for a few 

 months but it may change to reddish brown or pink. This species has 

 been reported previously only from the tidal zone in the Sea of Japan. 



About 12 specimens of Paramphithoe polyacantha (Murdoch) were 

 taken from Eluitkak Pass, from the beach, and from depths of 130 

 to 420 feet. This is a large, bright red-and-white species, with dorsal 

 and lateral spines. The males averaged smaller than the females : the 

 largest male was 22 mm. long, the largest female, 35 mm. 



Atyliis carinatus (Fabricius) was collected sparingly at Eluitkak 

 Pass and at about 10 feet along shore. This species, new to Alaska 

 and the western Arctic, occurs in Greenland mainly with Laminaria 

 and other algae (Stephensen, 1944). Except at certain areas of Elson 

 Lagoon, such algal growths are lacking at Point Barrow. Careful 

 collecting at Elson Lagoon might yield more of this species. 



Ensirus cuspidatus Kroyer, new to Alaska, was a colorful and com- 

 mon species in all hauls from 125 to 741 feet. It is reddish brown to 

 dull orange on a cream background, with dull orange-brown bands on 

 the antennae, and with crimson, bean-shaped eyes. Males from 25 to 

 38 mm. and females from 23.5 to 47 mm. were collected. Juveniles 

 from 2 to 8 mm. were taken at 125, 246, and 175 feet. 



Rhachotropis aculeata (Lepechin), new to Alaska and the western 

 Arctic, was taken at 80 to 328 feet. It is a colorful red-and-white 

 species with no two color patterns alike. Males were from 22 to 24 

 mm. and females from 23 to 39 mm. in length. 



Four specimens of Rocinante fragilis (Goes), new to Alaska and 

 the western Arctic, were taken from the stomach of an Arctic cod 

 (Boreogadus saida) that was caught in a fish trap on February 3, 

 1950, at 21 feet. 



A few Weyprechtia pinguis (Kroyer) were dredged at Eluitkak 

 Pass and at 80 feet. Several W. heuglini (Buchholz) were dredged 

 from the mud zone at 80 feet on July 21 and September 9, 1948. Sev- 

 eral were washed ashore, and 3 females were taken through the ice on 

 June 23, 1950, at 37 feet. Two of these females, measuring 43 mm. 

 in length, were developing marsupiums and were filled with oil. Both 

 these species are new to Alaska and the western Arctic, and the latter 

 to Arctic America.
