EXPEDITION TO POINT HAIMMUV, ALASKA. 



143 



This species was rather abundant and of large size on the muddy bottom along the shore in 

 2i to l~i fathoms. Only a few females were obtained. It was very often found washed up on the 

 beach during the season of open water, and occurred in especially large numbers after the great 

 gales of October, 1.S.S1. 



It is circumpolar in its distribution.

This species occurred in very great abundance on the rich bottom 10 miles west of Point 

 Franklin, in 13^ fathoms, and was rather plenty also at the head of Norton Sound, on a pebbly 

 bottom, in about 5 fathoms. 



The color when alive is a whitey-brown, clouded with bright crimson, generally forming crimson 

 patches on the terga of the segments and on the edges of the epiuiera, which sometimes coalesce, 

 forming bars across the head, the middle, and the end of the thorax. The peduncles of the antenna- 

 and the middle third of the flagclla are bright crimson. 



The species was originally described by Owen (loc. cit.) from the ' ; Arctic seas." Packard 

 secured one specimen at Sloop Harbor, Labrador, and it has also been recorded from the Gulf of 

 Saint Lawrence. Two specimens (Lockington's Idothea pulchra) were brought by W. J. Fisher 

 from the " west coast of Alaska, north of Bering Strait," and two specimens have been obtained 

 on the Grand Bank of Newfoundland. The Swedish expeditions obtained this species at various 

 points aloug the northern coast of Siberia from Nova Zenibla nearly to Bering Strait.
