184 feet; M. propinqua Sars, i specimen from no to 125 feet; 

 M. rohusta Sars, 3 specimens from 175 to 216 feet. 



Also forming first records for Alaska were Metopella nasuta 

 (Boeck), with i specimen from 341 feet and i from 741 feet, and 

 M. longimana (Boeck), with i specimen from Eluitkak Pass and 

 40 from depths of 100 to 341 feet. 



Ten specimens of Mesometopa neglecta (Hansen), also new to 

 Alaska, were collected from 80 to 216 feet, and 19 specimens of 

 M. gibbosa Shoemaker, n. sp., were taken from 80 to 420 feet. 



Two specimens of Stenothoe barrowensis Shoemaker, n. sp,, were 

 collected at 341 feet, and 19 specimens of Stenothoides angusta Shoe- 

 maker, n. sp., were dredged from 100 to 216 feet. 6". barrowensis is 

 a translucent white species with a translucent grayish-tan dorsum and 

 almost transparent appendages and shining orange-red eyes. 



Ten specimens of Proboloides nordmanni (Stephensen) were col- 

 lected from 80 to 217 feet. This species formerly was known only 

 from a single female taken from the southwest coast of Greenland. 



Two species of Metopelloides, both new to Alaska and the Arctic, 

 and each forming the second record of its occurrence, were collected : 

 I specimen of M. tattersalli Gurjanova came from 341 feet ; 5 specimens 

 of M. stephenseni Gurjanova from 5 to 5.5 mm. in length came from 

 120 to 217 feet. Even though it is small, the latter is a beautiful and 

 conspicuous species. The main portion of the body and the append- 

 ages are either transparent or else translucent white. Just posterior to 

 the head there is a broad transverse band of bright reddish orange 

 that extends to the tips of the ostegites, and another broad band of 

 the same color extends across the posterior portion of the thorax. 

 The small round eyes are of the same bright color, but have a more 

 shining and metallic appearance. This species is new to America and 

 the western Arctic. 



About 25 specimens of Acanthonotozoma serratum (Fabricius) 

 were dredged from 125 to 216 feet. This species is beautifully colored 

 with almost round, white eyes. The body in some specimens is irregu- 

 larly striped transversely with orange red and white or with pinkish 

 red and white ; in others it is almost a solid pink or peach color with 

 the tail portion white. No two color patterns are exactly alike. The 

 color fades out completely in preservative. This species is new to 

 Alaska and the western Arctic. 



A few specimens of Acanthostepheia malmgreni (Goes), new to 

 Arctic Alaska, were washed ashore. Acanthostepheia behringiensis 

 (Lockington) was obtained chiefly from specimens washed ashore, but 

 it was dredged also at Eluitkak Pass and alongshore in water from
