tracked approximately the same parcel of water. The 

 surface salinity ranged from 33.1 1 to 33.I5"/oo and the 

 surface temperature ranged from 4.1 to 4.5°C, as 

 measured by a constantly recording salino- 

 thermograph. 



ANNOTATED SPECIES LIST 



Below are notes on each species, including total 

 numbers collected, lengths when available, relative 

 abundance, and taxonomic notes. Where pertinent, 

 remarks on diurnal variation in numbers or occurrence 

 are made, as well as comments on the species' occur- 

 rences in relation to previously known depth and geo- 

 graphic distributions. 



Abbreviations used are: P = pereopod; S = seg- 

 ment; A = antennae. 



Cyphocaris anonyx Boeck 



One specimen in one haul. Length: 3.4 mm. 



Guryanova (1962) stated that Cyphocaris anonyx 

 ". . . inhabits a depth of no less than 500 m," and 

 Birstein and Vinogradov ( 1958) consider it a species of 

 the "upper deep-water subzone," ahhough they did 

 take it in one haul of 0-600 m. The occurrence of the 

 present specimen in a 0-212 m haul is thus somewhat 

 unusual. 



The present specimen is a first record for the Bering 

 Sea and represents a northward range extension from 

 lat. 43°N in the North Pacific (Guryanova, 1962). 



Cyphocaris challengeri Stebbing 



One hundred and six (106) specimens in seven 

 hauls. Length: up to 16.7 mm. 



This species is the most common epipelagic gam- 

 maridean amphipod in the subarctic Pacific (Bowman 

 and McCain, 1967). Its occurrence was limited to 

 hauls between about 2015 on 8 June and 0200 on 9 

 June, suggesting a diurnal vertical migration. Bow- 

 man and McCain reported that it was caught mainly 

 at night off Oregon and California, and attributed this 

 to a diurnal vertical migration. Maximum numbers of 

 our specimens occurred at night, when they comprised 

 13% of the total catch during haul 12 and when an 

 estimated concentration of 48/1,000 m^ was encoun- 

 tered during haul 13. 



Birstein and Vinogradov (1955) reported the species 

 from the western Bering Sea near the Commander Is- 

 lands at about lat. 58°N, and Thorsteinson (1941) re- 

 ported it from about lat. 57°30'N in the Gulf of Alaska. 



Lanceola sayana Bovallius 



One specimen in one haul. Length: 9.7 mm; female. 



Vinogradov (1957) noted that this species is usually 

 taken at depths over 1,000 m, although it frequently 

 occurs in surface catches at night. Bulycheva (1955)

 Phronimidae 



Phronima sedentaria (Forskal, 1775) 



reported the species from the western Bering Sea, but 

 stated that it was absent from the western North 

 Pacific Ocean off the Kurile Islands. Thorsteinson 

 (1941) did not report it in catches from the eastern 

 North Pacific Ocean. 



The telson of this specimen is relatively short, but it 

 fits Vinogradov's (1957) description of L. sayana in 

 other respects. 



Scina borealis (Sars) 



Four specimens in three hauls. Length: 1.6-7.5 mm. 



The species is reported as common in the Arctic 

 (Vinogradov, 1957) and off California (Hurley, 1956). 

 Thorsteinson (1941) reported it from the Gulf of 

 Alaska and coastal British Columbia, Canada. 



Scina stebbingi Chevreux 



Three specimens in one haul. Lengths: 1.6, 4.5, and 

 4.8 mm; latter two males. 



Vinogradov (1957) reported only one specimen, but 

 stated "It is known only from the southwestern Bering 

 Sea to latitude 58°08'N." 



Scina rattrayi Wagler 



Two specimens in two hauls. Length: 4.4 and 5.9 

 mm; males. Another male from a 0.505-mm net sam- 

 ple.
