NO, 9 MARINE INVERTEBRATES, ALASKA — MacGINITIE i6i 



lo to 15 feet deep. This species is gray above, with sometimes a 

 suggestion of tan, and light beneath, and the eyes are black. It is new 

 to Alaska and Arctic America. 



Seven specimens of Monoculodes horealis Boeck were washed 

 ashore on September 22, 1949. This species is whitish, and the large, 

 single, shining eye, situated toward the tip of the long rostrum, is a 

 pale-peach color. Three specimens of M. latimanus (Goes) were 

 dredged from no, 120, and 741 feet. This species varied from cream 

 to pinkish white. A few specimens of M. schneideri Sars were also 

 found. An ovigerous female M. packardi taken at 80 feet on March 

 29, 1950, was transparent pale orchid and the eggs were a transparent 

 greenish. The eye, similar to that of M. borealis but nearer the tip of 

 the rostrum, was much larger in proportion to the size of its body than 

 that of M. horealis. All four species are new to Alaska. 



Two specimens of Aceroides latipes (Sars) were taken at 80 feet 

 on March 29, 1950. They were translucent white except for the distal 

 ends of the appendages, which were lavender. 



Three specimens of Syrrhoc crcmdata (Goes) were taken at 216 

 feet. The body was transparent with a few splotches of orange red 

 and with large reddish-peach eyes shining like a headlight at the very 

 top of the head. This species is new to the western Arctic. 



Apherusa glacialis (Hansen) was one of the abundant species at 

 Point Barrow, where it was found chiefly under ice cakes (see intro- 

 ductory remarks on the "Amphipoda"). This pelagic arctic species 

 is circumpolar in distribution. Stephensen (1944) reports it from 

 east Greenland from the stomach of a seal, a young Phoca foetida, 

 and Dunbar (1942a) has reported it in plankton from east and south- 

 east Baffin Island, and from the stomach of Phoca hispida. The 

 amphipod is grayish white and the round, rather large eyes are dark. 



A female Pleustes panoplus (Kroyer) was dredged at 80 feet and 

 an ovigerous female was taken in a screen trap on March 10, 1950, 

 at 37 feet. The eggs, which were in the two-celled stage, were a 

 translucent yellow orange averaging 788 microns in diameter, includ- 

 ing the membrane. The dorsal portion of the body of the amphipod is 

 a splotched, mottled, and speckled effect of pale brown, reddish brown, 

 brown, red, and chalk white. The ostegites and rostrum are mainly 

 olive and gray with chalk-white spots and a little red. This is the first 

 record from Alaska. A few specimens of Pleustes medius (Goes), 

 also new to Alaska and the western Arctic, were taken at 217 to 420 

 feet. 



Sympleustes pulchellus (Sars), new to the western Arctic, was 

 taken sparingly at 125, 438, and 453 feet, and S. kariana Stappers,
