I/O SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I28 



On August 12, 1948, a female king crab Paralithodes camtschatica 

 (Tilesius), with a carapace lOO mm. long and the longest leg 185 mm. 

 in length, was picked up near shore at Point Barrow base. Men work- 

 ing along the shore about half a mile from the base reported seeing a 

 few others during the morning but an immediate search as soon as the 

 information reached the laboratory failed to yield any other specimens. 

 The crabs apparently had moved on. This female, which still had 

 empty egg cases clinging to her pleopods, was cream with markings of 

 brownish red. On September 4, 1948, an ovigerous female of this 

 species was picked up near shore at the native village — and, needless 

 to say, was summarily eaten. Although the beach at the base was 

 patrolled more frequently in the summer of 1949 than in 1948, no 

 more specimens were seen. 



Chionocetes opilio (O. Fabricius) was taken at five stations from 

 30 to 1 10 feet and one male was taken at 438 feet. Those from the 

 30-foot depth were a muddy brown but those from deeper water were 

 a reddish brown, the pigment extending onto the upper surface of 

 the legs. The dactyls and the entire lower surface were white. No 

 ovigerous females were found. With the exception of the one from 

 438 feet, all the specimens were taken in 1948, suggesting that they 

 stay closer to the shore when ice floes are present than when the ice 

 is completely absent. 



Class ARACHNOIDEA 

 Order PYCNOGONIDA 



About 10 species of pycnogonids, 6 of which have been identified, 

 were collected. For these names the writer is indebted to Dr. Joel 

 Hedgpeth, who is still working on about 30 lots belonging mostly to 

 the genus Achelia, a difficult genus with more than its quota of taxo- 

 nomic problems. 



NympJion hrevirostre Hodge was taken at 150, 80, 125, and no 

 feet (September 16, 1948). One of the specimens from 125 feet was 

 a male bearing eggs. Known largely from the Arctic north of Nor- 

 way and Russia and with a record from Kamchatka, this species is 

 new to the western Arctic. 



Nymphon grossipes (Fabricius) was the most abundant of the three 

 species of Nymphon. An ovigerous male was taken at 125 feet and 

 one at 120 feet (August 8, 1949), one specimen at 420 feet and one 

 at 217 feet, and an adult and two immature specimens at 175 feet. 

 The following were found on the beach in 1949: 2 on July 23 ; 28 (i 

 immature) between September 9 and 12 ; 9 (including 2 ovigerous
